Agm Battery State Of Charge Chart. The state-of-charge is how much charge is left within a single deep cycle battery or a solar battery bank. This is most accurate when the battery has been removed from a load for at least 6 hours preferably 24 hours.
Batteries should be boost charged if the open circuit voltage voltmeter reading is below 124 volts. The table below gives you the typical open-circuit voltages of a 12-volt AGM battery at each State of Charge from 100 down to 0. If you have an adjustable load meter set the load.
Being at rest will allow the batteries to stabilise and.
Use a voltmeter to determine the OCV. The State of Charge of the battery is determined by measuring the off-load voltage after the battery has been allowed to rest for over 3 hours. 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. AGM lead-acid batteries are used on practically all electric scooters bikes and go karts.
