Can anyone recommend a UPS that has a temperature sensor in the battery bay on the battery packs, and stops charging if the batteries get too hot?
Yesterday my little 1300VA home APC UPS started beeping wildly, and apparently the batteries are totally dead now.
So I open the battery bay, disconnect the leads and YEOUCH these batteries are HOT. Something like 160+F, almost sizzling hot.
Y'know I may not be a battery charger expert here, but if the gel-cel AGM batteries are 90F over ambient, maybe the device should STOP CHARGING them. Maybe?
Also, um, maybe cooking them at high temperature might be part of why the batteries are failing, after only 3-5 years of basically sitting there doing nothing but float-charging, and a 10-sec load test every two weeks?
We've used APC model UPS at work for the last decade and this is very common. APC just doesn't do thermal monitoring of the batteries, and frequently cooks batteries to death.
I've come into the server room to find the whole room smelling like rotten eggs, due to "sealed" dying lead acids boiling out anyway in an APC Smart-UPS.
I'm really getting tired of this charging behavior.
