How to Keep a Prius Battery Charged?
If you own a Toyota Prius, one of the most critical maintenance tasks is keeping the battery charged. The good news is this is easy to do and only takes a few minutes each month.
Here’s what you need to know about keeping your Prius battery charged:
- The first thing to understand is that there are two different types of batteries in your Prius – the hybrid and the 12-volt auxiliary batteries. The hybrid battery powers the electric motor and assists in starting the gasoline engine. It’s under the rear seat and lasts 10 years or 150,000 miles.
- The 12-volt auxiliary battery powers accessories like the headlights, radio, and climate control system. It’s located in the trunk and has a lifespan of 5 years or 60,000 miles. It’s essential to keep both batteries charged because if either one runs low on power, it can cause problems with your car.
- For example, if the hybrid battery isn’t properly charged, it can cause reduced fuel economy and increased emissions. If the 12-volt auxiliary battery runs low on power, it can cause problems with accessories like your headlights or radio. Click here to find out how long it takes to charge your Prius battery.
To keep both batteries adequately charged, there are a few things you need to do:
| Number one | First, ensure you’re regularly driving your car – at least once a week for short trips and every couple of weeks for long trips. This will ensure that both batteries stay topped off with power from the alternator. |
| Number two | Second, if you notice any drop in performance from either battery (dimmer headlights or shorter range on electric power), take your car to a Toyota dealer for service as soon as possible. They can test both batteries and determine whether they need to be replaced or recharged. In most cases, simply recharging the batteries will solve the problem. |
| Number three | Third, avoid leaving your car parked for long periods of time without starting it up at least once every week or so. |
