What Voltage Is A Flat 12v Battery. Answer 1 of 5. Is that low enough to cause problems so its the 12v not the hybrid battery From other places on PC I get 12 volt battery.
Answer 1 of 5. Fully charged according to the battery charger but the voltage is 124 or less the battery is sulfated. If a fully charged AGM battery tests more than 20 percent lower than the fully charged voltage level its probably due for replacement.
At what voltage is a 12v battery dead.
Same after removing 12v ground from battery replacing but 12vbattery at terminals car OFF reads 123v which is about half charge for what should be a fully charged battery. If the battery is loaded the voltage will depend a lot on how much current is being drawn for the numbers see above. The charge voltage must be compensated if the environmental temperature deviates from 25ºC. Battery voltage state of charge table.
