BX1500G no longer seeing charged battery
I have a BX1500G that shows an estimated "run time" of only 1 minute and the graphical display indicates a single bar. All other indicators are normal. If I disconnect the main power, the UPS immediately goes into alarm and will shut down within the first minute. The battery is fully charged at 27 volts. Swapping fully charged batteries does not change the situation. The load is only 200 watts.
Is there anyone on this forum that knows how the battery test/monitoring circuit works?
It would appear there is some issue with the circuit that detects the status of the battery.
