Hi all
I am currently using a Mecer all in one as a UPS .When doing a test I switch off the mains supply and run on two 100ah gel batteries in series. If i let the battery voltage go below 24 volts and switch the mains supply back on the charger stars to charge in bulk mode with the voltage increasing till 28.2 volts It then stays there and never goes back to float voltage . This was from 9:45 am till 17:30. Surely this is not correct what can be done about it?
