If the voltage reading of a battery is below 12.2 volts, it may need to be charged or replaced. A voltage reading of 11.9 volts or less indicates that the battery is discharged and needs to be charged immediately. Specific Gravity Test To determine the state of charge of ...
The capacity of a battery is the amount of energy that the battery can store. This is usually measured in milliampere-hours (mAh) or ampere-hours (Ah). The higher the capacity, the longer the battery will last. Battery life is the amount of time that a battery can provide power before it needs to be replaced or recharged.

If the battery is still good, then the voltage level will only drop slightly. ... Learn how solar panels work and unravel the mysteries of how solar power works. We''ll ...
If you use it for more than 3-5 years, the battery is probably losing its ability to hold the charge. To check, disconnect battery terminals, leave it for 2-3 hours and check the voltage on contacts. You can use a regular multimeter for this; connect it to the battery connector while observing polarity (plus to plus, minus to minus).

The battery capacity test measures how much capacity (current x time) in ampere-hours, Ah, the battery can deliver before the terminal voltage is reached. The measurement assumes the current flow shall be maintained at a constant rate. For a lead-acid battery, the test time is approximated to be near the battery''s duty cycle.
