A hybrid car’s efficiency is largely dependent on its battery, which is why it’s a good idea to get it tested and replaced about every 10 years. Below is a list of potential diagnostics that could be the result of an under-performing battery, and you might want to consider getting it replaced.
Fewer Miles To The Gallon
Finding yourself visiting the gas station more often than usual? You might want to consider getting your battery replaced. Several factors can impact your miles per gallon (MPG), including cold weather and tire pressure. However, if you find yourself revisiting the gas station more frequently, it could be that your electric power isn’t taking over your internal combustion engine (ICE) as often as it should. In other words, the battery isn’t retaining its charge and needs to be replaced.
Uncontrollable Engine Input
If your engine is running for longer than usual, or cutting in, then you might want to have your battery checked. This is a common problem and most likely a sign of a dying battery.
Charging Problems
As you drive your hybrid more, you should get a better understanding of how quickly your battery discharges. However, things can go wrong with your charging and discharging rates, which usually indicate an issue with your battery.
Charging State
If you notice significant fluctuations in the charge of your car while driving, your battery might have issues that require inspection. While a certain level of fluctuation is normal, especially if you’re starting and stopping your car often, a fluctuation of greater than 5% is sufficient to get your battery checked, and possibly replaced.
Unexpected, Strange Noises
In some cases, your fan may run for longer and more intensely than usual, which means your battery is getting too hot. Often a warning light will give some sort of indication that this issue needs to be addressed, but as always, it is best to consult a technician if you’re unsure.
Keeping your battery in check is important to maintain a durable and efficient hybrid. Hybrid cars are only as efficient as their battery allows, so if your car is underperforming, then you might want to consider getting the battery inspected.
