ES 750 lasting less than 1 minute on good battery

Anonymous user · ‎2021-06-29

Hi!

I have three ES 750's. I replaced the batteries in all three of them 6 months ago. Now one of them lasts less than 1 minute during power outages, with ~40W load. It should last hours. I swapped the battery in the unit with one of the working ones... and when I unplug power it beeps and switches off in less than 1 minute with the known good battery.

Any ideas of things to try, short of replacing the bad unit?

This is a BE750G, first 6 of serial 3B0742.

Hi andrew, if you have replaced the battery (and also tried the unit with a good know battery) then unfortunately there is not too much more we can do. Are these APC genuine batteries you have running in these units here?

Hi R2,

Thank you for your reply!

Yes these are genuine APC replacement batteries. I think the unit itself has just died. It's in use in community powered by diesel-generated power, and has a rough life, up and down, up and down, :-(. I'll just replace it.
