Can certainly verify polarity but I don't think I have anything on hand to do a load test. If the UPS wakes up with the old batteries then the new ones go back & I'll lean on the store for a load test. I'm guilty of not questioning my assumption that the new batteries were good!

I'd say that expecting "new" ( as in recently purchased ) products to be 
in perfect shape ( unless ebay or made from chinesium, that is ) is a 
fair assumption. Practice teaches us that not all fair assumptions are 
also true :)

Now, in the event that the UPS will refuse to come up even with the old 
batteries, I suggest a careful inspection of the electronic board, of 
the cables and especially of capacitors and places where the cables are 
soldered. Capacitors DO age with time and a bad connection ( maybe a 
cable just got loose ) may prevent proper functioning.
