What size battery does my car take?


What size battery does my car take? What size battery do I need for my car? What is the best car battery for my car? Can I upgrade my car battery to bigger size? Can I downgrade my car battery to smaller size? Car manufacturers always suggest consumer to use the recommend battery size written in the user’s manual when the battery needs to be replaced. However, many of us do not know how car battery replacement work and here are some guides to choose the right battery size for your cars.

Car battery size or car battery group size refers to the dimension of the battery, which is the length x height x width. Battery makers manufacture different size of car batteries because different cars have different battery tray. You must find the exact battery size that best fit to the battery tray securely. Too big is impossible while too small is impractical.

Check out the owner’s manual and there will be a page to tell you the specific battery group size of your car. If you have lost it (it’s alright, many people lost their owner’s manual), you can download it from the internet. Otherwise, consult car accessories shop, auto stores, spare parts shop, or mechanic to find out the appropriate battery size for the car. The easiest way is to take the old battery to auto parts store and get a new one!
