ExpertPower 2-Pack 12V 3.3Ah Rechargeable Sealed Lead Acid Battery

The original batteries in a couple of APC uninterruptible power supply (UPS) units I had eventually wore out and wouldn't keep things powered up more than about two minutes. These were easy drop-in replacements for the original batteries, and now the UPS units can run a PC or switch for about a half-hour again.

3/21/22, The two pack arrived much earlier than originally expected. Both seemed new and in good shape. They fit right into both of my backups. I had slightly different model numbers but the size and connectors seemed the same, and they were. They fit right into place and turn on and pass the self test. I'll update this review in the future if I run into any problems. Hopefully they last a few years at least....

Worked fine as direct replacement to the UPS. Will see how long this lasts.

I bought two of these, in advance of the current batteries dying.The batteries stayed good for a while but when I tried to use the new ones, they both were unusable.They had no shelp life.I am way outside the window for returning them and will probablly take them to the local dump for recycling.A total waste of money. Buying from APC will cost way more than these but I will be certain the quality of replacements will be tops.

I ordered two the came fairly quick. I tested both seemed very good will update after I used for awhile

Double batteries use an adapter between them. Line it up, use the original tape and you are good to go

Cheap

...and I mean cold as in winter thermostat settings.Summer is set at 74f and winter is 68f.They both started failing the self-test on the same night and were fine during the day, then set off alarms the next night.Really annoying to wake up to two APC UPS, in the middle of the night to shut them down....and, of course my window to send back ended on 10/30...
