CyberPower RB1270X2 UPS Replacement Battery Cartridge, Maintenance-Free, User Installable, 12V/7Ah

Used in cyberpower 900avr. Third or forth time I have replaced batteries in various cyberpower units. Easy enough to get access to battery, but getting the old battery unhooked can be a challenge. A slight pry with a small flat blade screwdriver helps loosen a stuck connector. Also can be a challenge getting wires to lay flat enough for front panel to close. A lot of fiddling is required due to their engineering for minimum size and shortest wiring possible. Opted to spend more rather than much cheaper knockoffs, since it is for a business PC.

Perfect exact OEM Replacement for my CyberPower 900AVR the batteries also come connected, so no messing around, simple replacement through front panel.

It works just fine. Fits my backup power supply.

Only needed 1 of the two(twin pack), but was a dream to install. UPS back on line!

I had to take the batteries out of the old cyberpower1350pfclcdAPC bracket and put these into the battery sled. The battery connectors that shipped with this module were not compatible with the APC UPS. The batteries themselves are fine - nothing special lead acid batteries so they themselves will work perfectly. it was just a pain having to retrofit a new item when it was advertised as a FFF replacement.

UPS units use lead-acid batteries which have a limited life, especially if draw down power. A simple replacement is cheaper and more environmentally friendly than throwing the whole unit out. Still waiting for a decent low priced Lithium ion based UPS but this is as good as it gets for now.

I just bought the battery in January - lasted until February 16th.

Worked without a hitch.Installation was tight, but once connectors were aligned, I had no problems.
