How to Replace Batteries in Hybrid Vehicles

Learn to replace the battery in your hybrid vehicle so that you are prepared in a pinch.

The lithium-ion battery in your hybrid vehicle is meant to last for the lifetime of the car. Unless there is a defect, it is unlikely you will ever have to replace your hybrid's battery. Most warranties cover the battery for 8-10 years, so if you are within that period, there's no reason you need to replace the battery yourself. But if for some reason you do need to change your hybrid's battery on your own, it can be done.

Things You'll Need

• Ratchet wrench

Instructions

1. Buy a new lithium-ion battery that is compatible with your particular model of hybrid car.

2. Refer to your owner's manual to locate the placement of your model's battery. It will be located in the front or back of the car.

3. Disconnect all plugs and cables attaching the old battery to the engine. Make note of the order you removed them in so you can replace them in reverse order.

4. Remove the housing bolt (if present) using a ratchet wrench. Pull the battery out and place it somewhere safe to await disposal.

5. Place the new battery in the space you removed the old one from. Replace and tighten the housing bolt (if present). Reattach the cables and wires in the same manner you removed them.

6. Dispose of your old battery properly. This usually consists of making a call and having it picked up and disposed of by a professional at your expense. Some hybrids will have a phone number on the battery that you can use.
