Posted April 13, 20231 yr On a 2kw Axpert I have two gel batteries in series, 120a each. With a puny load of 100w after an hour or so the voltage plummets out of nowhere from 24.6v to 22.4v and the low voltage alarm starts and shortly after the inverter switches off. If I turn the inverter off a multimeter shows the voltage goes back to 24v, turn the inverter on and back down to 22 we go, confirmed by a multimeter. These batteries are 3 months old, are gel batteries really that useless or is something wrong here?
