What is the Expected Lifetime of a Car Battery?

Most car batteries today are completely enclosed and do not allow access to the interior to provide maintenance. The water in a battery will naturally evaporate over time leaving a thick sulfuric acid that is no longer capable of producing voltage. Another concern inside the battery is the continuously declining condition of the positive and negative poles.

In batteries that are enclosed there is no way for the owner to add water to the battery. Hence, the lifetime of the battery cannot be extended through added maintenance, and the battery will naturally expire in five to seven years. In batteries, with removable caps above the poles, the owner has the opportunity to provide more water with electrolytes to extend the life of the battery.

At our service center here at LaFontaine Ford of Birch Run in Birch Run, MI, we check your battery voltage levels to maximize your batterie’s usable life.
