I have bought two new batteries for my ups.
The batteries are 12V 7 Ah lead technology agm. The batteries are connected in series. The batteries are from the same date of manufacture.
The batteries came charged at 12.82V and 12.85V. I have charged the batteries separately with a three stage charger. The second stage at 14.4V. The charger gives the option of charging at 14.7V.
Once the batteries are charged, I have mounted them on the ups. When connecting the batteries to the ups, the voltages are 14.4V and 13.7V for each battery. After two hours the voltage of each battery drops to 13.7V and 13.5V.
Should I worry about the imbalance of the two batteries?
Will the imbalance of the two batteries disappear in the next few days?
