Perform a capacity test. Short duration load tests and impedance/conductance measurements are not reliable to determine the actual capacity of a battery.

Lifeline® AGM batteries contain a pressure relief valve (PRV) that prevents excessive pressure buildup when the battery is being charged, and automatically reseals once the pressure is released. A slight bulge in the battery container (convex end walls) can appear...

For a battery at room temperature, it can be considered fully charged with the charging current falls below 0.5A per 100Ah of rated capacity. The open circuit voltage (after at least 4 hours of rest) will be 2.17 volts per cell or higher (13.0 volts for a 12-volt...

NONE! Charging voltage varies widely depending on the battery’s temperature and there is no single voltage that will work over a wide temperature range. Batteries will fail prematurely if this is attempted.

Charge with a 3 stage charger that compensates the voltage setting as teh battery temperature changes.
