I've seen that behavior in a Symmetra from APC, but our unit is old  
enough to have ZERO trade-in value. The battery trays swelled so much  
that we had to dis-Assemble the UPS to get them out, but I didn't  
consider that when making my recommendation because the OPs needs were  
an order of magnitude lower.

APC rackmount-class UPSes have a great track record, in my experience.  
My only other experience was with wet cells in telco switching centers.

I'd agree with Liebert for a datacenter-level need.
