Remove the cover from the APC UPS , one screw needs to be removed, and the batteries can be exchanged while the attached users are in operation. No need to turn anything off as long as the power is available from the 110 V source.




It's a big battery. A big, HEAVY battery. 75 pounds. I tipped the UPS guy for having to lug it from his truck. Is it being heavy a pro or con? It's not really a pro, but I don't know how you'd avoid it, so it's not really a con. Why can't they make batteries out of Aerogel? Have only had it a few weeks. Have gone through one power outage and it performed as advertised. I guess I was drawing less current than I thought, because the runtime looks to be longer than I thought (based on how fast the battery was draining).

OEM Battery - gives the warm fuzzies that it won't blow up.
