APC UPS

S

Had two fail in 12 hours. I only have one spare. I was surprised to find replacement batteries at Home Depot. Saved me a 60 mile drive. It is cheaper to get them on line but sometimes you can't wait.

BTW they claim they will recycle your old ones

That's the problem with replacing batteries at the same time. They die about the same time. Usually during a night, weekend, vacation, or holiday.
For all the UPS's I used to deal with, I'd make a calendar appointment on my phone and workstation eighteen months out to replace certain batteries and spread them out over a year. In other words, replace them before they die.
 
Henry Engineering makes a box that will automagically bypass the UPS should it fail. I believe it also provides an alarm/contact closure if it goes into bypass mode.
 
UPS batteries do have some special requirements. Haven't had any worse life out of non-APC batteries in the APC.
DO NOT USE DURACELL THEY'RE CRAP

That box only handles 15 amps. Many of our UPS units are 2200 kVA units on a 20 amp circuit.
 
When I was at UPS (No pun intended) they had a policy to test every 3 months and replace the battery immediately if they failed, and once the warranty went out replace it completely.
