Safety Precautions

Although reconditioning a Prius battery is easy, you should always follow all the safety measures before starting. Remember, you are dealing with a battery here, and you never know when an accident can take place. Here are some of the essential safety precautions that you should keep in mind before, during, and after reconditioning the battery.

  • Keep the tools and materials in a secure place for reconditioning. You can even use a Prius Reconditioning Kit available at hardware stores.
  • Wear your protective attire like mask, gloves, and goggles before starting the reconditioning process.
  • Always work in a well-ventilated area. If you are working in your garage, keep the door and windows open. Also, make sure you have a good supply of water before starting.
  • Check the polarity of the wires and circuit while working. This should reduce the risks of short-circuiting or even electrocution. Prius batteries usually produce 100 to 300 Volts, which is dangerous enough to electrocute you.

Reconditioning Prius battery

First of all, you don’t need to open the Prius battery to recondition it. You just need to conduct deep charging cycles to bring the battery up to speed. Given below is a step by step guide on what you have to do.

Step 1

Connect the charger to your Prius battery and keep it on a long charging cycle. All the modules should show their respective charging status.

Step 2

Keep checking the modules from time to time. Once they reach their maximum capacity, disconnect the charger. It’s now time to drain the battery fully.

Step 3

Drain the charge of the Prius battery. Then, let the battery rest for at least an hour before you put it in the next full deep charging cycle. Make sure the modules read 0% before connecting the charger to the battery.

Step 4

You should repeat the first three steps, 3 to 5 times continuously. This should show a significant change in battery backup. The battery would charge faster than before and discharge slowly. It means the battery is back from its sleep mode.

Step 5

If you don’t want to go through this rigorous procedure, you can buy a Prius Battery Reconditioning Kit and follow the instructions in the manual.

Prius Battery Reconditioning kits cost nearly a hundred bucks, which is still cheaper compared to a new battery. If you follow the reconditioning instructions carefully, you may end up using the battery for another six years.

Frequently Asked Questions on Prius Battery Reconditioning

Those who are reconditioning a Prius battery for the first time may have various questions regarding the entire process. Here are some of the most frequently asked questions on Prius battery reconditioning that should clear all your doubts:

1. What happens when a Prius battery goes bad?

Most of the time, Prius batteries last between 4 to 6 years. But even before that period comes to an end, you may have to face the problem of a faulty battery and a warning light that asks you to get it replaced. Once you experience this issue, you may ask yourself, “What happens when a Prius battery goes bad?”

The most common issue that’s associated with the Prius batteries is a parasitic power drain. They consume power even when they are not being used. For example, when your car is off, all the modules except lights will have to be switched off to prevent parasitic power.

You should ideally follow a battery reconditioning procedure to provide a new life to the battery. Some people also recommend copper tape to plug the leakage. But everything boils down to reconditioning the battery to improve its backup time and lifespan.

2. How often do I need to charge and discharge the Prius battery to make it last longer?

Ideally, you should recondition your battery at least once in three to six months. It ensures that the battery is in proper condition and can carry a maximum charge for a significant period without discharging quickly.

3. Can I keep the battery idle at room temperature?

You can, but it would lose nearly 30 to 50% of its charge over time, even if you don’t use it. That’s the issue with all types of NiMH batteries. They discharge quickly if you keep them at room temperature. Ideally, you should keep the batteries in a cool place that doesn’t have moisture to keep the charge intact.

But it’s not possible to pack a Prius battery in an airtight bag and keep it in the freezer. The best thing to do is to use the battery once you finish reconditioning it. That not only keeps the battery healthy but also increases its lifespan by a few years.
