Several indicators that reveal the health of your car battery:

When you need to do a battery test for your vehicle, there are several indicators that reveal the health of your car battery.


The top one is its capacity representing its energy storage. Theoretically speaking, a new battery should deliver its full capacity, which indicates end of battery life.


State of charge (SoC): the level of charge of an electric battery relative to its capacity. The units of SoC are percentage points (0% = empty; 100% = full). SoC is normally used when discussing the current state of a battery in use.


State of health (SoH) is a figure of merit of the condition of a battery (or a cell, or a battery pack), compared to its ideal conditions. The units of SoH are percent points (100% = the battery’s conditions match the battery’s specifications).

A battery’s SoH will be 100% before it’s used and will decrease gradually due to time and use.
