[TurnerFam]

my inverter had this condition, and it was found that two cells in one of the four batteries were 'low', their specific gravity was not even registering - now, I originally 'refreshed' this battery by draining it, refilling with distilled water, charging overnight... again, and still again, then filling with battery acid. It solved the problem, the battery then worked fine, and with all four the inverter stayed solid when powering outlets and appliances for month, and months afterwards.

About a year later I replaced all the 5 year old batteries with Duracell GC2's from Batteries+Bulbs as they were also on sale there and at Sams Club for $99 each. What I liked about B+B is that they put them on a flat 'roller cart' and allowed me to wheel them out to my Motorhome, parked on the far other side of the large parking lot, and replace/install them there, at my leisure, and bring back the 'trade ins'...
I did replace two battery cables to provide a better 'connector' than the original, but otherwise everything was the same. These batteries have been installed for a year now, have a great time frame when on the inverter, and still look brand new, with no growths at the cable ends/terminals like the last ones.
