ALREADY TESTED. WORKED VERY WELL!

I have several old Liebert UPSs with VRLA (gel cells) batteries but they don't last long and never seem to have enough power when I need them for work. Just a day after installing this new lithium-ion pack, there was a momentary power outage of about 10-15 minutes and my computer and networking gear stayed up and running properly. I will never go back to lead acid batteries! Another nice feature is that the lithium block is noticeably lighter.

Pros
