A utile item for determining the amount of power remaining in a battery is a tester, which may come in a assortment of styles depending on what type of battery is being examined. Some testers are built right into the battery, others are built into the item that the battery is being applied for, and most are portable and may be applied for a great deal of varieties of batteries.

Sometimes a tester is self-powered, meaning all of the energy that is necessitated to test the battery comes from the battery itself, while other types of testers require their own power source to operate. Others types of testers may be built right into the battery itself, and a mutual type of this tester uses a particular type of conductive ink. When two leads are pressed, the ink will appear and shows how much power remains in the battery along a printed gauge.

The displays on these testers may determine the remaining power of a battery in terms of percentage, which may be crucial in measuring the capacity of the battery to begin an engine.
