Hello everyone, I have a battery related question and need some advice.
I have a battery bank, 12V, deep cycle lead acid batteries and they are connected to a "smart" AC-sourced charger, which eventually switches to float mode. I believe that's around 13.2V.
At the same time I have an inverter connected that unfortunately draws about 1A at standby. Because the charger appears to have a current limit (I am guessing), the battery voltage eventually drops and stabilizes at 12.55V.
Is this too low for long-term storage? I guess my batteries aren't fully charged anymore at that voltage, are they?
My understanding is the batteries should be kept at around 13V float voltage.
Should I add another charger or some power supply to bring the voltage up to 13V?
Or is there another charger I should buy that can supply more current at the float stage?
Thank you!
