Testing

Batteries should be carefully inspected on a regular basis in order to detect and correct potential problems before they can do harm.

It is a great idea to start this routine when the batteries are first received. SEE "When installing or commissioning NEW batteries."  

Visual inspection alone is not sufficient to determine the overall health of the battery. Both open-circuit voltage and specific gravity readings (for flooded batteries) can give a good indication of the battery’s charge level, age, and health. Routine voltage and gravity checks will not only show the state of charge but also help spot signs of improper care, such as undercharging, overcharging and over-watering in the case of flooded batteries, and may  possibly even locate a bad or weak battery.

SEE "When installing or commissioning NEW batteries." 

When preparing to test the batteries first make sure they have been fully charged.

The following steps outline how to properly perform routine voltage and specific gravity testing on batteries.
