How To Tell If Battery Is Agm. To deliver powerful bursts of amps and to run electricity for a long period of time. Check the manufacturers label on the Battery.
The easiest way to determine whether you have an AGM battery is to read the label. A fully charged AGM battery has an output voltage of about 13 volts. Look at the top of the battery.
If a fully charged AGM battery tests more than 20 percent lower than the fully charged voltage level its probably due for replacement.
The simplest way to determine the State of Charge of an AGM battery is to measure the battery no-load or open-circuit voltage this is the voltage across the battery poles when no load is connected. Typically a fully charged deep cycle battery will have a voltage of over 128V - 13V. Usually all the batteries have labels and other information about the battery provided by the manufacturer. To deliver powerful bursts of amps and to run electricity for a long period of time.
