Hi,
I just bought a used UPS, as is. Looks in fine condition and is
3000kva for $100. The batteries need replacing and seem to be swollen
or stuck in the case (5U rack mount). Really can't seem budge them at
all, and I don't want to break them and make a mess. From what is
visible, I see no leakage, but a crack along the seam of the case on
one. It bulges a bit at that point, so I think they're swollen stuck.
There look to be 4 x 12Volt 17AH sealed lead acid batteries in there.
Any suggestions greatly appreciated. I would hate to hack out the
battery bucket because it is all riveted, but if I have to I will. I
don't see any way to push them out from the back, and if necessary to
do so, I may have to drill a hole but would probably hit a battery in
the process.
Other thoughts may include silicone spray and heat guns. I really
don't have an aproach yet. Would they shrink if I charged them?
What might cause the swelling? Overcharge? Cold temperature storage
without charging? Failure to replace when necessary?
Thanks in advance for any ideas!
Regards,
Jim
