Of the most important parts in a car is it's battery, without such device it is virtually impossible to start the engine. Starting the engine is not the only function it serves, it also provides extra power for ignition, lighting, and it becomes active if the combined demand for power surpasses the one provided by the charging system so without it your car is obviously going nowhere. Since this part is critical for any car to work, learning how to improve its life and performance is information worth acquiring.

Depending on the type of car you use the battery life fluctuates, some will last 4-5 years, others will go above that, but every once in a while we hear about batteries lasting only a couple of years. According to today's battery prices which range between USD $80 - $250+ constant replacement can surely turn out to be an annoying expense.

In order to improve your car's battery life you can follow these steps:

- If you have purchased a fairly new car, the battery it comes with is pretty generic (for most cars), replacing or upgrading it can keep you worry free for quite some time.

- If your new battery dies after a couple of years it is important to find the reason why it died so fast instead of buying a bigger battery, in some cases the insulation around the battery is not good enough and it tends to discharge its power faster so replacing it with a bigger one will pretty much yield the same results in term of its life. Make sure to have good insulation which will keep the battery's electrolytes at the right temperature. If temperature is an issue then you could have the battery installed in your car's trunk which will keep it properly isolated from temperature changes and additional equipment which can affect its life.

- Keeping your car's lights always functional is very important but there are those who like to add extra accessories to the car which drain its power, the same goes for people who love 1000 watt speakers and powerful stereo amplifiers. Such accessories can drain a battery extremely fast so it is highly recommended to install a separate power supply for such accessories. Also use the right battery charger when the time comes.

- Keep track of the average amount of miles driven each day as well as the average time spent stuck in traffic jams if you live in a crowded area, this will help technicians determine the best course of action when it comes to insulation and location.

Follow these basic guidelines and you will increase your battery life and decrease unnecessary expenses.
