I have a query regarding sealed lead acid battery.
· I am using 7.2 Ah 12 V sealed acid battery in our machine. Now if the charger is charging the battery and after some hours if the battery voltage measured by charger is more than 12.7 V and the battery charging current is less than 100 mA.
· So under this condition is it right to say the capacity of the battery now is more than 7.2 Ah or we need to really measure the battery capacity with some measuring instrument to really know that battery capacity has reached more than 7.2 Ah.
· This though has come in my mind cause I think that If the plates are damaged, sulfated, or partially gone from long use, the battery may give the appearance of being fully charged by showing more than 12.7 V and consuming less than 100 mA charging current in the battery charger display and still the capacity of the battery is very low.
