How to Know if You Need to Change Your Car Battery

The battery is one of the most important parts of your vehicle as it is responsible for starting your car and powering all other functions that require electricity, like the computer, lights, wipers, etc. A car battery will have an average lifespan of 3-5 years, but taking proper car battery care can make it last for a longer period of time. Unfortunately, at some point, your battery will run out of power, and it is important to know when you should change the car battery so you are not left stranded at the most inconvenient times. 

A slow starting engine is one of the main indicators that your battery is failing is when it takes a longer time for your engine to turn over. Gradually, over time the active materials inside your battery will degrade and become less effective in creating cranking amps for the starter motor. The check engine light is lit
