UPS Battery Replacement:

3/18/2003 - Latest from Tom Tyner: Two to three years ago some of us bought a Liebert UPS from Jerry Lee [@ Omni-Teq]. The battery in mine has failed (it had a life expectancy of 2 - 3 years) and I imagine others will soon. 

I have found an almost exact replacement (12 AH instead of 10 AH OEM) in ES1212 from Exide Technology, 4647 Pine Timbers, Houston 77041, 713-862-6584. Cost is $39.86 including tax. The physical dimensions
are identical.

To access the battery, you need a Phillips screwdriver and a 7/64 Allen wrench at least 3 1/2 inches long. The top front and button rear screws require the wrench. The spade terminals on the new battery are slightly higher, perhaps 1 - 2 mm, than on the original battery. It is only necessary to ensure that
the flat side of the female terminal connector is on top of the negative terminal.

I thought others may find this useful. Tom - Thanks for that insight! GB
