After 1 and a half year continuous running, my combination of homage inverter and Osaka IT-1000 battery has started showing signs of trouble. I have to say it is more to do with the homage inverter than the battery. The inverter now slowly keeps on charging the battery and does not shut off as it used to do before. The result is that the battery remains warm to touch and needs to be topped off more often. The problem is not a big deal right now but it will get worse from now on.
I assume the battery has gotten old and can not now reach the homage cut-off voltage of 15.4 V (I think). I am surprised that Homage inverters' 2-stage charger does not have a ability to detect the battery strength and cutoff charging when the battery can not accept any more charge.
The system otherwise is performing well. Still gives me an hour worth of coverage during load shedding. I am reluctant to take it to a tech and have the inverter adjusted because I am afraid if I get this factory sealed unit opened once, it will never be able function right again if I ever decide to attach a new battery to it in future.
Does anybody have any solution?
