When it’s time to replace a battery, the right choice depends less on a universal “best” and more on the device that needs power. My strongest fit for barcode scanner owners is the Artisan Power 730 mAh NiMH, which matches several Zebra, Symbol, and Motorola models and can use compatible existing chargers. For Black & Decker 20V tool owners, the two-pack of 4.0Ah lithium-ion batteries offers spare capacity for longer work sessions. The Rayovac D-cell 12-pack is the straightforward choice for household devices that take disposable D batteries.

These picks serve very different jobs, so capacity numbers are not directly comparable: a scanner’s 3.6V NiMH pack, a 20V tool battery, and a 1.5V alkaline D cell are not interchangeable. I rank them by how clearly each option matches its intended equipment and solves a replacement need. The tradeoffs are model compatibility, rechargeability, and how much battery capacity or supply you actually need.
Key Takeaways
- For compatible LS4276, LI4278, DS6878, and LS4270 scanners, Artisan Power provides a 3.6V, 730 mAh NiMH replacement and supports use with compatible existing chargers.
- The Black & Decker option is a two-pack of 20V lithium-ion batteries rated at 4.0Ah each; confirm tool compatibility and treat the listing’s inconsistent capacity wording cautiously.
- Rayovac’s 12 alkaline D cells suit devices designed for D batteries, but they are single-use and should not be mistaken for a rechargeable replacement.
- Battery chemistry, voltage, connector, and physical fit must match the device; a higher capacity figure alone does not make a battery suitable.
- Choose the pack size to match actual use: two tool batteries help maintain a spare, while a 12-pack of D cells may be excessive for occasional use.

Artisan Power Replacement Battery for Zebra/Symbol LS4278, LI4278, DS6878 Barcode Scanners (BTRY-LS42RAA0E-01, 82-67705-01)
For a scanner owner trying to get a familiar handheld back into service, the Artisan Power replacement is the most directly specified option in this group. It is a 3.6V NiMH pack rated at 730 mAh, with listed compatibility for the Zebra, Symbol, and Motorola LS4276, LI4278, DS6878, and LS4270. The named replacement part numbers—82-67705-01 and BTRY-LS42RAA0E-01—give buyers another way to check the old battery before ordering.
Its strongest practical advantage is that it is described as working with existing compatible chargers. That may spare a buyer from replacing the charging setup along with the battery, although the charger still needs to be appropriate for the scanner and battery. The stated Japanese cells and Taiwan assembly provide sourcing details, but do not establish how long the pack will last in a particular scanner. Compared with the Black & Decker option, this is a narrower, equipment-specific replacement rather than a general-purpose tool battery; compared with Rayovac’s D cells, it is rechargeable and designed for a particular device family.
The limitation is fit: this is not a generic scanner battery, and similar-looking models may use different packs. It is also an aftermarket part, so buyers should not assume it carries the same warranty or support as an original manufacturer battery. I’d choose it when the scanner model and battery number match, but skip it if either detail is uncertain or if an OEM-only warranty matters more than a direct replacement.
Pros:- 730 mAh capacity in a rechargeable NiMH format
- Lists several Zebra, Symbol, and Motorola scanner models
- Identifies two replacement part numbers for fit checks
- Designed to work with compatible existing chargers
Cons:- Aftermarket warranty and support may differ from OEM coverage
- Compatibility is limited to the specified scanner models
- The stated capacity alone does not establish real-world scanner runtime
Best for: Owners of a listed Zebra, Symbol, or Motorola scanner who have verified the model or replacement part number and want a rechargeable battery compatible with their existing suitable charger.
Not ideal for: Anyone with an unlisted scanner model, an uncertain charger match, or a requirement for an original-manufacturer battery and warranty.
- Battery type:NiMH rechargeable
- Voltage:3.6 V DC
- Capacity:730 mAh
- Energy:2.6 Wh
- Compatible models:LS4276, LI4278, DS6878, LS4270
- Replaces:82-67705-01; BTRY-LS42RAA0E-01
- Cell origin:Japan
- Assembly:Taiwan
Our verdict“I rank this first for its clear scanner-specific fit and rechargeable design, provided the buyer verifies the model and part number.”
Upgraded 2 Pack 4.0Ah 20V Max LBXR20 Replacement Battery for Black and Decker
For someone replacing a battery in a compatible Black & Decker 20V cordless tool, this two-battery lithium-ion pack is the choice that puts spare capacity at the center. Each battery is described as 20V and 4.0Ah, and the two-pack means one can be charging while the other is in use. That setup can matter more during a long task than carrying a single replacement with a larger advertised capacity.
Compared with Artisan Power’s scanner pack, this battery serves a broader household tool platform but still depends on exact system compatibility. It is not a substitute for the 3.6V scanner battery, and its 20V label does not make it suitable for other brands or voltage platforms. Unlike Rayovac’s D cells, these are rechargeable tool batteries with built-in electronics described as guarding against overcharging and malfunctions.
There is a meaningful listing caveat: one specification says 4000mAh, while the description calls the batteries 4.0Ah. Those values are equivalent when correctly stated, but the supplied product information also includes a separate, apparent “4000Ah” typo. I would confirm the label and compatibility before relying on the capacity claim. The stated one-year warranty is another limit, and the supplied notes flag concerns about longevity without giving enough detail to predict the life of any individual pack. This pick makes sense when two batteries are useful and the tool is confirmed compatible; skip it if you need a clearly documented OEM replacement or cannot verify fit.
Pros:- Two lithium-ion batteries provide a ready spare
- Listed at 20V and 4.0Ah per battery
- Designed for Black & Decker 20V cordless tools
- Built-in microchip is described as protecting against overcharging and malfunctions
Cons:- Capacity wording is inconsistent, including an apparent 4000Ah typo
- The stated warranty period is one year
- Long-term battery life is not established by the supplied specifications
Best for: Black & Decker 20V cordless tool owners who want two rechargeable batteries to keep a spare available during extended work.
Not ideal for: Owners of other tool brands or voltage platforms, buyers who need a longer warranty, or anyone unwilling to verify the listing’s capacity and compatibility details.
- Battery type:Lithium-ion
- Voltage:20V
- Stated capacity:4.0Ah (also listed as 4000mAh; verify product labeling)
- Stated energy:54Wh
- Package:2 batteries
- Compatibility:Black & Decker 20V cordless tools
- Weight:1.6 pounds
- Warranty stated:1 year
Our verdict“I recommend this as a spare-ready replacement for verified Black & Decker 20V tools, with the capacity notation checked before purchase.”
Rayovac High Energy D Batteries (12 Pack), Alkaline D Cell Batteries
Rayovac’s 12-pack of alkaline D batteries is the simplest replacement here, but only if the device is designed for D cells. These single-use 1.5V batteries suit items such as compatible flashlights, toys, and stereos. A stated shelf life of up to 10 years can also make a multipack useful for keeping spares in storage rather than running out when a battery-operated device is needed.
That convenience differs sharply from the first two picks. Artisan Power is a rechargeable pack made for a short list of scanners, while the Black & Decker batteries are rechargeable parts for a specific cordless-tool platform. Rayovac is the option for a device with a D-cell compartment, without a charger or tool-platform fit question. Its leak-prevention feature is intended to help protect devices, but it does not remove the need to check and replace batteries according to the device maker’s guidance.
The main tradeoff is single-use power: once depleted, these cells need replacing rather than recharging, creating more waste and ongoing battery consumption. The 12-count pack may also be more than a light user needs. I would pick it for several D-cell devices or a household that wants stored spares, not for a device with a rechargeable pack or a different battery size. D cells are physically larger than common AA or C cells, and adapters are not a substitute for checking the device’s instructions.
Pros:- Twelve cells provide multiple replacements or stored spares
- Up to 10-year shelf life is stated
- Leak prevention is intended to help protect devices
- Suitable for compatible high-use household devices
Cons:- Single-use cells cannot be recharged
- A 12-pack may exceed the needs of occasional users
- Disposable batteries create recurring waste
Best for: Households with flashlights, toys, stereos, or other devices specifically designed for alkaline D cells, especially when keeping spare cells on hand is useful.
Not ideal for: People seeking a rechargeable battery, buyers with only occasional D-cell use, or anyone whose device takes a different battery size or chemistry.
- Battery type:Alkaline
- Cell size:D
- Voltage:1.5V per cell
- Pack size:12 batteries
- Reusability:Single use
- Stated shelf life:Up to 10 years
- Stated battery weight:133.6 g
- Stated item dimensions:6.2 x 4.8 x 2.45 inches
Our verdict“I’d choose Rayovac for a supply of D cells for compatible household devices, but not as a rechargeable alternative to the scanner or tool batteries.”
How We Picked
I organized these recommendations around the moment a buyer realizes a device battery needs replacing: the old battery no longer holds charge, runtime is falling short, or a household device needs fresh cells. Since the three products serve unrelated equipment, I did not treat them as competing batteries for one device. Instead, I compared each with the need it claims to solve and gave each a distinct role.
My ranking prioritizes clear device fit and useful replacement details. The Artisan battery leads because its listed scanner models, replacement part numbers, chemistry, voltage, and capacity give scanner owners a concrete compatibility check. The Black & Decker pack comes next for users of the brand’s 20V tool platform, with the advantage of two batteries and lithium-ion chemistry balanced against a listing inconsistency and limited stated warranty. Rayovac fills a different, simple need: replacement D cells for devices that take alkaline batteries, with a long stated shelf life but no recharging.
I also considered the practical cost of getting the match wrong. Voltage, chemistry, connector style, battery dimensions, and the manufacturer’s compatibility guidance matter more than a broad claim of “long life.” I cannot infer independent performance or device-specific runtime from the supplied specifications, so I avoid treating promotional claims as guaranteed results. Before ordering, compare the old battery’s label and your device manual with the replacement details.

Factors to Consider When Choosing Time To Replace A Battery
When a battery starts failing, I begin with the device’s original battery label and manual—not with the biggest capacity figure in a listing. These three products belong to separate battery systems, so the right comparison is about a correct replacement, not which number looks largest.
Match the device and replacement number
Check the manufacturer, model number, and original battery part number. The Artisan pack lists LS4276, LI4278, DS6878, and LS4270 scanners plus two replacement part numbers, giving scanner owners specific checks to make. The tool pack is described for Black & Decker 20V cordless tools, while Rayovac is for devices with a D-cell compartment. A product that looks close is not necessarily a fit: connector shape, locking tabs, and battery dimensions can differ even when two batteries share a voltage.
Treat voltage and chemistry as compatibility details
Voltage and chemistry need to match the device’s requirements. The scanner replacement is 3.6V NiMH, the tool pack is a 20V lithium-ion battery, and each D cell is 1.5V alkaline. Those figures describe different applications and cannot be ranked on one scale. Do not replace a rechargeable pack with disposable cells, or the reverse, unless the device maker explicitly allows it. Check the manual for approved battery chemistry and charger guidance.
Read capacity in context
Capacity can help compare compatible batteries of the same kind, but it does not promise a particular runtime in every device. The scanner battery lists 730 mAh and 2.6 Wh; the tool pack lists 4.0Ah and 54Wh; the Rayovac product lists cell voltage but no capacity figure in the supplied specifications. These numbers are not directly comparable across chemistries and devices. For the Black & Decker listing, note the inconsistent “4000Ah” wording and confirm the battery label rather than assuming the typo is a reliable specification.
Choose rechargeable or disposable based on use
A rechargeable replacement is a better match when the device already uses a rechargeable pack and repeated battery purchases are inconvenient. The Artisan battery is for compatible scanners; the Black & Decker pack provides two rechargeable batteries for its tool platform. Alkaline D cells make sense when the device is built for disposables or when ready-to-use spares matter more than recharging. The tradeoff is recurring replacement and waste, especially with high-use devices.
Check the charger, warranty, and amount you need
Do not assume an old charger is compatible simply because a replacement battery fits the device. The Artisan description says it works with existing compatible chargers, but buyers should verify the exact charger. Tool-battery buyers should check the manufacturer’s guidance and the included warranty details; the provided listing information states a one-year warranty. Finally, consider pack size: a two-pack is useful if a charged spare keeps work moving, while twelve D cells may be excessive for a single low-use device. Buy the quantity that suits your actual devices and replacement habits.
Frequently Asked Questions
How do I know when it’s time to replace a battery?
Replace a battery when it no longer holds a useful charge, runtime has dropped enough to disrupt the device, it fails to power the device, or the device’s instructions call for replacement. First rule out a charger, connection, or device fault where practical. For rechargeable batteries, follow the device maker’s charging and safety guidance, and stop using a pack that is damaged, swollen, leaking, or unusually hot.
Can I use any of these three batteries as a general replacement?
No. Each serves a different battery system: Artisan Power is listed for specific barcode scanners, the two-pack is for compatible Black & Decker 20V tools, and Rayovac supplies alkaline D cells. Check the device model, required battery size, voltage, chemistry, connector, and approved charger. Similar voltage or a larger capacity figure does not make a battery interchangeable.
Which option is rechargeable?
The Artisan Power scanner pack uses rechargeable NiMH chemistry, and the Black & Decker tool batteries use rechargeable lithium-ion chemistry. Rayovac’s D cells are single-use alkaline batteries. Rechargeable does not mean universally compatible: use only a charger and battery type approved for the particular device and pack.
Should I choose the Black & Decker battery pack if I need more runtime?
It may suit an owner of compatible Black & Decker 20V tools who wants two batteries and a spare ready to use, but the listing’s capacity wording needs care. It describes 4.0Ah or 4000mAh, while a separate “4000Ah” entry appears inconsistent. Verify the battery label and tool compatibility, and do not treat capacity alone as a guaranteed runtime figure.
Is a 12-pack of D batteries a good choice for occasional use?
It depends on how many devices use D cells and how often they need replacements. Rayovac states a shelf life of up to 10 years, which can suit households that want spares ready, but a 12-pack may be more than one occasional-use device requires. Check the device’s battery size and storage instructions, and remember that these alkaline cells cannot be recharged.
Conclusion
My recommendation depends on the device you are bringing back into service. For owners of a listed Zebra, Symbol, or Motorola scanner, I’d start with Artisan Power after confirming the scanner model, part number, and charger; it is the most precisely specified fit in this group. For a compatible Black & Decker 20V tool, the two-battery lithium-ion pack makes more sense when keeping a spare matters, but I would verify the capacity notation and warranty details. For several household devices that take D cells, Rayovac’s 12-pack is a practical supply choice; occasional users with one device may not need that many. In every case, match the replacement to the battery label and device manual before ordering.
