Car batteries are consumables, have a certain life expectancy, and need to be replaced after a period of use. The car battery can generally use 2-5 years, depending on the type of battery, use and maintenance. If usually properly maintained, coupled with good car habits, car battery life can be extended to a certain extent, you can use 4-5 years.

Car batteries are divided into maintenance-free batteries and ordinary batteries (lead-acid batteries), most of the current models use maintenance-free batteries, while most Japanese cars use ordinary batteries. Ordinary battery electrode consists of lead and lead oxide, electrolyte is an aqueous solution of sulfuric acid, life expectancy is generally about 2 years, so two years a change is the most reasonable. Maintenance-free batteries are relatively durable, and are generally replaced once every 3 years or so.
