For August smart lock batteries, I’d start with the Duracell CR123A 6-pack as the best overall choice: it pairs a familiar battery brand with a practical pack size and a stated 10-year storage life. The Amazon Basics 6-pack is a straightforward alternative for shoppers who want a similar quantity, while the Energizer 123 12-pack suits households that prefer to keep a larger reserve on hand. The main tradeoffs are pack size, storage claims, and how much brand familiarity matters to you—not a promise that one battery will last a set amount of time in every lock. Check your August lock’s manual for the required battery type before ordering, since compatibility varies by model. Read on for the full comparison and a guide to choosing the right pack for your setup.

More Details on Our Top Picks
Duracell CR123A 3V Lithium Battery, 6 Count, 10-Year Storage, High Power
For an August lock that takes CR123A cells, I’d choose the Duracell six-pack when familiar branding and stored spares matter more than rechargeable use. Its listed 1,500mAh capacity and 3-volt output suit devices that need lithium cells, while the 10-year storage guarantee makes it practical to keep replacements on hand. Compared with the Amazon Basics six-pack, Duracell’s supplied data does not claim higher capacity; its distinction is the specific storage guarantee and stated performance across extreme temperatures. The tradeoff is that these are single-use batteries, so frequent replacements create ongoing waste and require buying another pack. Check your August lock’s manual before ordering: this is a CR123A option, not a universal August battery, and compatibility depends on the lock model.
Pros:- Six CR123A cells provide a ready set of replacement batteries.
- 3-volt lithium output and listed 1,500mAh capacity.
- 10-year storage guarantee supports keeping spares for later.
- Described as suitable for a wide temperature range.
Cons:- Single-use cells cannot be recharged.
- The product data does not establish compatibility with every August lock model.
- Its listed capacity is lower than NINMAX’s stated 1,700mAh.
Best for: August lock owners whose specific model calls for CR123A batteries and who want a familiar-brand six-pack for replacement stock.
Not ideal for: Owners of August models that use AA batteries, rechargeable cells, or another battery format; also a poor fit for buyers seeking reusable cells.
- Brand:Duracell
- Model number:5008630
- Battery format:CR123A lithium
- Quantity:6
- Voltage:3 volts
- Capacity:1,500mAh
- Storage guarantee:10 years
- Reusability:Single use
Our verdict“Pick Duracell for stored CR123A spares and brand familiarity, but only after confirming your August lock uses this battery format.”
Amazon Basics 6-Pack Non-Rechargeable CR123A Lithium Batteries, 3 Volt, Up to 10-Year Shelf Life
The Amazon Basics six-pack is a straightforward choice if your August lock specifically uses CR123A batteries and you want clearly stated capacity and shelf life. Each cell is listed at 1,550mAh and 3 volts, with up to 10 years of storage—useful for keeping replacements in a drawer without planning to use them soon. That capacity is slightly above the Duracell pack’s listed 1,500mAh, though the supplied information does not establish a meaningful difference in lock runtime. Unlike the NINMAX 12-pack, this pack avoids stocking a larger quantity than many households need. Its drawbacks are clear: the cells are not rechargeable, and the listing warns they are not suitable for Arlo cameras. Most importantly for this roundup, neither the pack name nor its data confirms compatibility with every August lock, so verify the required battery type first.
Pros:- Six CR123A lithium batteries in one pack.
- Listed capacity of 1,550mAh per cell.
- Up to 10-year shelf life for keeping spares.
- Non-rechargeable design is clearly specified.
Cons:- Single-use batteries cannot be recharged.
- The supplied data specifically excludes Arlo security cameras.
- August model compatibility is not confirmed by the product details.
Best for: August lock owners with a confirmed CR123A requirement who want a six-cell pack with stated capacity and long storage life.
Not ideal for: Buyers whose August model takes a different battery size, or households looking for rechargeable batteries or cells for Arlo cameras.
- Battery format:CR123A lithium
- Quantity:6
- Voltage:3 volts
- Capacity:1,550mAh
- Shelf life:Up to 10 years
- Rechargeable:No
Our verdict“Choose this pack for clearly specified CR123A replacements, provided your August lock manual calls for that format.”
POWEROWL CR123A 3V Lithium Battery – Pack of 6
POWEROWL’s six-pack makes the most sense when CR123A batteries serve several household devices, not just an August lock. The product description names cameras, flashlights, and smoke detectors, and it claims up to 10 years of shelf life plus performance in extreme temperatures. That broad-use positioning gives it an advantage over a pack chosen only for a single replacement job. However, the supplied specs do not state a capacity or exact dimensions, so I can’t compare its expected runtime as directly with Amazon Basics’ 1,550mAh cells or NINMAX’s 1,700mAh listing. It is also single-use. For August buyers, the missing capacity data matters less than the missing model-specific compatibility: confirm the lock calls for CR123A cells, and treat POWEROWL as general-purpose spare stock rather than a guaranteed lock match.
Pros:- Six lithium manganese dioxide CR123A cells.
- Described as having up to 10 years of shelf life.
- Product description covers cameras, flashlights, and smoke detectors.
- Designed to perform in extreme temperatures.
Cons:- Capacity is not specified in the supplied product data.
- Dimensions are not provided, making direct fit checks harder.
- Single-use cells cannot be recharged.
Best for: Households that already use CR123A batteries in multiple devices and want a six-cell pack with stated long-term storage suitability.
Not ideal for: Buyers who need a documented capacity, exact dimensions, or confirmation that the cells fit a particular August lock model.
- Battery format:CR123A
- Chemistry:Lithium manganese dioxide
- Quantity:6
- Voltage:3 volts
- Reusability:Single use
- Stated shelf life:Up to 10 years
- Dimensions:Not specified
Our verdict“Consider POWEROWL for shared CR123A household spares, but choose a better-documented option if capacity or exact fit is your priority.”
NINMAX CR123A 3V Lithium Battery 12 Pack
If your home uses CR123A cells across several devices, NINMAX’s 12-pack offers the largest quantity in this group and the highest stated capacity: 1,700mAh per cell. That makes it the clearest choice here for buyers who want a larger reserve, rather than the six-cell stock offered by Duracell, Amazon Basics, POWEROWL, and Voniko. Its listed 10-year shelf life and operating range of -40°F to 160°F also suit long-term storage and demanding environments. The main tradeoff is quantity: a buyer replacing batteries only occasionally in one lock may have more cells than needed. These batteries are single-use, and the product data does not confirm fit for any particular August model. I’d only choose them after checking the lock manual’s battery requirements.
Pros:- 12 batteries provide the largest pack quantity in this group.
- Listed 1,700mAh capacity is higher than the stated capacities of the other specified packs here.
- 10-year shelf life supports keeping reserve cells.
- Specified operating range of -40°F to 160°F.
Cons:- A 12-pack may leave infrequent users with unused cells.
- Single-use batteries cannot be recharged.
- The supplied data does not confirm compatibility with specific August lock models.
Best for: Households or property managers with multiple CR123A-powered devices who want a larger supply and a stated 1,700mAh capacity.
Not ideal for: Someone replacing one August lock’s batteries who wants a small pack, rechargeable cells, or confirmed model-specific compatibility.
- Battery format:CR123A
- Quantity:12
- Voltage:3 volts
- Capacity:1,700mAh
- Chemistry:Lithium manganese dioxide
- Shelf life:10 years
- Temperature range:-40°F to 160°F
- Reusability:Single use
Our verdict“Choose NINMAX for a large CR123A reserve across several devices, not for a one-off August battery replacement.”
Voniko CR123A 3V Lithium Battery (6 Pack), High Capacity for Smoke Alarms, Flashlights, Home Automation
Voniko’s six-pack is aimed at buyers who want CR123A spares for security sensors and home automation, with a leak-proof design claim and up to 10 years of shelf life. Its listed 1,500mAh capacity matches Duracell’s stated capacity, while Amazon Basics lists 1,550mAh; those figures alone do not establish how either will perform in a specific August lock. Voniko’s fit here is its stated use across home-automation devices, not a confirmed August endorsement. The pack is single-use, and the listing says it is not recommended for Arlo cameras, narrowing its usefulness if you share batteries across devices. As with every CR123A option in this roundup, I’d check the lock’s manual before buying; August models may call for a different format.
Pros:- Six CR123A lithium-metal batteries.
- Listed 1,500mAh capacity and 3-volt output.
- Up to 10-year shelf life for stored replacements.
- Leak-proof design claim and stated extreme-temperature performance.
Cons:- Single-use cells need replacement after depletion.
- Not recommended for Arlo security cameras.
- The product data does not confirm compatibility with specific August lock models.
Best for: August lock owners with a confirmed CR123A requirement who also want spare cells for sensors or other home-automation devices.
Not ideal for: Buyers seeking rechargeable cells, batteries for Arlo cameras, or a model-specific guarantee of August lock compatibility.
- Battery format:CR123A
- Chemistry:Lithium metal
- Quantity:6
- Voltage:3 volts
- Capacity:1,500mAh
- Shelf life:Up to 10 years
- Reusability:Single use
- Battery weight:96 g
Our verdict“Pick Voniko for stored CR123A spares across compatible home devices, after confirming your August lock uses this battery type.”
Enegitech CR123A 3V Lithium Battery, 2 Pack
The Enegitech two-pack suits August lock owners who need a small reserve rather than batteries for several devices. Its listed 1600mAh capacity is higher than the 1200mAh listed for the Energizer 12-pack, though capacity figures alone don’t establish how long either battery will run in a particular lock. Enegitech also specifies built-in PTC protection, a useful safety feature for household security equipment. Like the Energizer options and the six-count Duracell CR123A, these are single-use lithium batteries, so they can’t be recharged after depletion. The main tradeoff is quantity: two cells are convenient for a targeted replacement but leave little backup for multiple locks or sensors. Check your August lock’s battery requirements before buying; compatibility varies by lock model.
Pros:- Two batteries suit a single replacement need without a large surplus.
- Listed 1600mAh capacity.
- Built-in PTC protection is specified.
- Up to 10 years of standby power is claimed.
Cons:- Single-use cells must be replaced after depletion.
- Only two batteries are included, limiting household backup supply.
- CR123A compatibility must be confirmed for the specific August lock model.
Best for: August lock owners who have confirmed their model uses CR123A cells and want just two batteries for a replacement or modest backup.
Not ideal for: Households maintaining several August locks, sensors, or alarms, since a two-pack provides less spare capacity than the Energizer 6- or 12-pack.
- Battery type:Lithium, non-rechargeable
- Voltage:3V
- Capacity:1600mAh
- Pack quantity:2 batteries
- Weight:31g
- Standby power claim:Up to 10 years
- Protection:Built-in PTC protection
Our verdict“Choose this small pack for a confirmed CR123A-compatible August lock when you don’t need a larger household reserve.”
Energizer 123 Lithium Batteries (12 Pack), 3V Photo Batteries
The 12-pack Energizer 123 is the strongest fit here for buyers stocking several compatible devices, not someone replacing one lock battery and stopping there. Its 10-year shelf-life claim supports keeping spares on hand, while the larger pack gives more reserve than Enegitech’s two-pack or Energizer’s own six-pack. The listed 1200mAh capacity is lower than Enegitech’s stated 1600mAh, but capacity numbers from different product listings don’t by themselves predict runtime in an August lock. These are single-use cells, and the listing describes them for cameras, flashlights, and smart home sensors rather than naming August locks specifically. I’d check the lock’s manual for battery type before choosing this option; the larger quantity is useful only if you have compatible devices to use them in.
Pros:- Twelve batteries provide the largest reserve among these three picks.
- Up to 10 years of shelf life is claimed.
- Described for use in smart home sensors and other high-tech devices.
- Useful for maintaining backup stock across several compatible devices.
Cons:- Single-use cells cannot be recharged.
- The 1200mAh listed capacity is lower than Enegitech’s stated 1600mAh.
- The product description does not specifically confirm compatibility with August locks.
Best for: Owners of multiple confirmed CR123A-compatible locks or smart-home devices who want a substantial supply of stored replacement batteries.
Not ideal for: Someone replacing batteries in one lock who has no other compatible devices, since most of this 12-pack may sit unused.
- Battery type:Lithium 123
- Voltage:3V
- Quantity:12 batteries
- Model number:EL123BP12
- Capacity:1200mAh
- Reusability:Single use
- Shelf-life claim:Up to 10 years
Our verdict“Pick this pack when several of your devices are confirmed to use 3V lithium 123 batteries and you want a long-term reserve.”
Energizer 123 Lithium Batteries (6 Pack), 3V Photo Batteries
The Energizer six-pack lands between Enegitech’s two-cell pack and Energizer’s 12-pack: enough spares for a modest group of compatible devices without committing to a dozen. Its listing gives a 1500mAh capacity, between Enegitech’s 1600mAh and the 12-pack’s 1200mAh figures, although those listing values aren’t a direct measure of August lock runtime. Like the larger Energizer pack, this one claims up to 10 years of shelf life and is single-use. That makes it a practical reserve for a lock plus other compatible household electronics, but not a rechargeable solution. The description mentions smart-home gadgets without naming August models, so I would verify the required battery type in the lock’s manual before buying. Compared with the 12-pack, the smaller quantity leaves less surplus for a multi-device setup.
Pros:- Six batteries offer a middle ground between a two-pack and a 12-pack.
- Listed capacity is 1500mAh.
- Up to 10 years of shelf life is claimed.
- Described as compatible with smart-home gadgets and other common devices.
Cons:- Single-use batteries must be replaced rather than recharged.
- The listing does not name August locks as a confirmed compatible device.
- Provides fewer spares than Energizer’s 12-pack for multi-device households.
Best for: August lock owners with confirmed CR123A requirements who want a moderate supply for one lock and a few other compatible devices.
Not ideal for: Buyers seeking rechargeable batteries or a large reserve for many locks and sensors; this pack is single-use and smaller than Energizer’s 12-pack.
- Battery type:Lithium 123
- Voltage:3V
- Capacity:1500mAh
- Pack quantity:6 batteries
- Reusability:Single use
- Weight:40g
- Dimensions:0.7 x 3.76 x 4.51 inches
- Shelf-life claim:Up to 10 years
Our verdict“Choose the six-pack for a moderate stock of confirmed compatible batteries without the larger reserve of the Energizer 12-pack.”
How We Picked
I compared the eight listings on factors that matter when buying batteries for an August smart lock: CR123A type and voltage, pack size, stated storage-life information, and how clearly each option fits a buyer’s likely replacement routine. Since the products here are non-rechargeable lithium batteries, I also treated easy-to-store spares and buying only the quantity a household can reasonably use as practical decision points. I did not assume a particular runtime in an August lock; usage, lock model, and conditions can affect battery life.
The ranking favors options with a useful balance of stated information, recognizable product positioning, and practical pack size. Duracell takes the overall spot for its six-count format and stated 10-year storage life. Amazon Basics follows as a direct six-pack alternative, while larger packs rank better for reserve-building than for every household. The smaller Enegitech pack has a clear role for buyers who need only a couple of batteries, but it offers less backup quantity. Before buying any pick, I’d verify the battery specification in the lock’s manual.

Factors to Consider When Choosing August Smart Lock Batteries
Choosing August smart lock batteries is less about chasing a single brand and more about matching the battery specification and pack size to your lock and replacement habits. These factors help avoid compatibility mistakes, excess stored batteries, and last-minute gaps when a replacement is needed.
Confirm the Exact Battery Type in Your Lock Manual
Start with the manual or support page for your specific August lock model rather than relying on a general search result. This roundup focuses on 3V CR123A batteries, but lock generations can differ in their requirements. Do not substitute a visually similar cell unless the manufacturer lists it as compatible. Check whether the instructions specify a quantity as well as a battery type. A correct pack in the wrong format is still the wrong purchase, so verification should come before brand or pack-size comparisons.
Choose Pack Size Around Your Replacement Routine
A small pack can make sense if you are replacing a limited number of cells or want to avoid storing extras for years. Larger packs, such as the 12-count options here, suit homes with several compatible devices or buyers who prefer to keep spares available. More batteries are not automatically better: unused cells take up space and may sit in storage for a long time. Think about how many your lock takes per replacement and whether other household devices use the same type. That simple count helps balance readiness against overbuying.
Treat Shelf Life as a Storage Claim, Not a Runtime Promise
A stated shelf life describes storage under specified conditions; it does not predict how long a battery will run your lock. Lock activity, connectivity, temperature, and usage patterns can all affect service life. If you keep spares, follow the package’s storage guidance and check the date or condition before installation. Avoid mixing old and new cells in a device unless the lock maker’s instructions say otherwise. This distinction helps prevent a common mistake: choosing a battery based on a storage claim as if it guaranteed longer operation in the lock.
Decide How Much Brand Familiarity Matters
This selection includes familiar names such as Duracell and Energizer alongside Amazon Basics and smaller-label options. A recognizable brand may be reassuring if you value established product naming and clear packaging, while a lesser-known label may suit buyers whose priority is simply finding the specified battery type in the needed quantity. Brand alone cannot establish compatibility or runtime. Compare the actual product details and packaging claims rather than assuming every CR123A listing is identical. If you cannot confirm the cell type or key specifications from a listing, choose one that states them clearly.
Plan for Spares Without Mixing Battery Sets
Keeping replacement batteries at home can be useful, especially when the lock signals that power is running low. Store spares together in their original packaging so the type and handling guidance stay easy to identify. When replacing multiple batteries, use a matched set of the same type and avoid combining partly used cells with fresh ones. Keep batteries away from heat and moisture, and follow the manufacturer’s disposal instructions for used cells. A modest, well-stored reserve is often more practical than buying the largest pack by default.
Frequently Asked Questions
Will every CR123A battery in this roundup work with my August smart lock?
These listings are for 3V CR123A batteries, but that does not prove compatibility with every August lock model. Check your model’s manual or official support information for the exact battery type and required quantity. If the manual names a different format, do not rely on a retailer title or a battery that looks similar. Also check that the package identifies the cell as CR123A and 3V. Confirming those details before ordering is the best way to avoid a mismatched pack.
Should I buy a 6-pack or a 12-pack for one lock?
Base the choice on the number of batteries your lock takes, how often you expect to replace them, and whether you have other devices that use the same type. A six-pack gives many households a useful reserve without committing to a large stock. A 12-pack makes more sense if you maintain several compatible devices or want replacements readily available for a longer period. If you are buying for one lock and have no other use for CR123A cells, a larger pack may leave batteries stored for a long time. Follow the package’s storage guidance whichever quantity you choose.
Does a 10-year shelf-life claim mean the battery will last 10 years in my lock?
No. A shelf-life claim refers to storage under stated conditions, not the operating time you should expect after installing a battery. Runtime in a smart lock can vary with model, usage, connectivity, and environment. Treat storage-life information as useful when deciding how practical it is to keep unopened spares, not as a guarantee of service life. For a more dependable replacement schedule, follow the lock’s battery alerts and manufacturer guidance. Replace the batteries when the lock indicates it needs them rather than relying on a calendar guess.
Is it safe to mix different CR123A brands in the same lock?
I would use a matched set of the same type and brand rather than mixing brands or combining new and partly used batteries. Different cells can have different histories and performance, which makes the set less predictable. Check the August lock instructions for any battery replacement guidance specific to your model. If the lock uses more than one cell, replace the set together when the manufacturer advises it. Keep the removed batteries separate for disposal or recycling according to local rules.
Which option makes the most sense if I only want a small backup supply?
The Enegitech 2-pack is the smallest option in this roundup, so it suits buyers who want only a limited backup quantity. It offers less reserve than the six-count Duracell, Amazon Basics, POWEROWL, and Voniko packs, or the 12-count NINMAX and Energizer options. Before choosing it, check how many cells your lock needs per replacement; a two-pack may be enough for one change only, depending on the model. If you want a spare set after replacing the current batteries, a larger pack may be more convenient. Match the quantity to your lock’s requirement rather than buying by pack size alone.
Conclusion
Best overall: I recommend the Duracell CR123A 6-pack for buyers who want a familiar brand, a practical quantity, and a stated 10-year storage life. Best value-minded alternative: Amazon Basics offers another six-count format with a stated long shelf-life claim. Best for beginners: the Duracell six-pack is a simple starting point, provided your lock manual confirms CR123A compatibility. Best premium-style brand pick: Energizer suits buyers who prefer a familiar battery name and want a choice between six- and 12-count packs. Best for a larger reserve: compare the 12-count Energizer and NINMAX options; choose based on your preference for brand familiarity and how many compatible devices you maintain. For a minimal backup, Enegitech’s two-pack keeps the purchase small. My final advice is to confirm your lock’s exact battery requirements first, then choose the pack size that fits your replacement plan.
