All batteries require replacing after they have been used for a certain period of time. The replacement of the hybrid car battery depends on the charging and discharging cycles. The current hybrid cars come with excellent, long lasting batteries that can last for up to 8 years or more but it is always wise to know when you need to replace them. An average car's lifespan is considered to be 150,000 to 200,000 miles by manufacturers and the batteries are built to last this long. You can keep a check on your mileage and replace it once you have used it for that many miles.
Most hybrid cars come with displays on the dashboard that indicate when you need to replace or charge your batteries. If you have been using the car for long, you will feel the difference in power in your car. Most hybrids use battery power at low speeds and if you find that your car is not performing as well as it should, you should get it checked by a dealer. Your hybrid electric battery will be under warranty for most of its life, so you don't have to worry about getting huge bills for replacement on your battery. You may have your service schedule with the dealership when it is under warranty. It is always a good idea to keep your car well tuned to improve its performance and increase its life.
Knowing a thing or two about cars can help you save hundreds you would otherwise have to give for the labor. Replacing the batteries is not rocket science and all you need is the right wrench and the hybrid battery replacement pack. Most auto dealers can provide you with the battery replacement pack. Know that it will not be cheap as this is the most important part of your hybrid car. You will have to carefully loosen the bolts that are present to hold the cables. The cable that is negative should be taken off first and the positive should follow. There will be bolts holding the strap tight which need loosening as well. Once you remove the strap, you will be able to remove the hybrid car battery pack. After you replace it with the new pack, bolt the straps and cables back down. You should take care how you discard the used battery pack. You can earn a few hundred dollars by sending the used batteries to the manufacturers as most good ones will collect the dead batteries.
The location of the hybrid batteries will differ from model to model. Reading your manual will help you find it. In some cars it is present in the front while in others it can be in the rear. It is important to remember how the connections are in the dead battery and make the same connections in the new pack as well. If you find that working with tools is not your thing, it is always safe to go to an auto dealer and get this done. Even your local auto repair shop should be able to replace it for you.
