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).

It works. It came fully charged (APC's literature made it seem like it would have to be charged for 6-8 hours before running self-test.)
