thanks for the reply.

i did a little experiment. i have a 2nd liebert unit (purchased at the same time). so i took it's case off, placed a new standard size battery in it, and turned it on after a cool down. i began making notes of what the battery voltage was, and the temp of this particular hot spot on the board, and recorded the same findings.

i figure it's a charging device action, to bring the 12v up to 13.8V (for whatever reason). the temp started to lower once the voltage got up.

i've since put the case back together on both, and have them operating now. once the second ups needs a new battery i'm defintely going to the larger size.
