Beiter DC Power APC Back-UPS XS 1200 Replacement Battery Kit of 2…

Worked great as a replacement. Cost effective. Went to a weird model number I had that said an APC BackUPS 1200 would work. Glad it did. After charging, UPS lights reflected a full charge. Works fine on my Ativa UPS. UPDATED 8/10/18. Red light flashing today. Thought it needed replacement but I looked at the documentation and it states that a flashing red light means it's just overloaded. It's if it's a solid red light that means it need replacement. So, I reviewed my recent changes and put some items onto the "non-battery" outlet. It took a few minutes before the flashing red light turned off. So, if you see some reviews that convey a flashing red light, it either does need replacement or it might be an assumption of that meaning, like I thought.

Great deal! Compared to APC official batteries, this is only $29.99 (free shipping and no tax for me), at a small fraction of the cost. I only have it for a short time but so far so good! You have to reuse the wires and the plastic board from the old APC batteries though. Easy install and I taped the new batteries together with duct tape.

Batteries only appear to have held a charge for the first month of use. My APC UPS began to flash the red "replace battery" indicator. I'm used to about 3 years from replacements. EDIT: just after posting this review, Beiter emailed me with a return shipping label and credited my account—so I've ordered a second set. This was excellent service; and I feel I must give them a second chance. It's possible that I was sent an set of untested batteries the first time. I will come back to this review and edit it one final time after the new batteries have been installed and had a few weeks to run.

I bought these to replace the batteries in my APC UPC 1200 XS power supply. The new batteries (they are made in China) seem to be of good quality although they did feel a bit lighter than the ones they were replacing (which were made in India). . I have not had it long so I don't know if they will last as long as the oem factory batteries that my APC came with. However, the price was fair and my unit is now functioning fine with them installed.

Great value for the price - pair worked flawlessly and exceeded manufacture life expectancy (3 to 5 years). Live in Florida with electrical storms and hurricanes. These batteries met the need and demands.

Batteries work great. Make sure to charge for 24 hours before plugging devices back into UPS. I didn't the first time, and the battery replace light went off after just a couple of days. I unplugged all the equipment, power cycled the unit, then let the batteries charge overnight (like the instructions said). The next day, I plugged everything back in and then the problem was resolved, been a couple of months now.

Getting the old battery out was a bit of a chore. Very tight fit and the cables impeded the removal. But the new one slid right in, easy to wire in place, and good to go.

Kit works in the Belkin F6C1500-TW-RK. Came charged to about 12.8v per battery and were a 1-to-1 replacement for my existing unit. Just installed them so I cannot speak to the longevity, but they are made in china (just like the originals) and they came with a 2yr warranty, so I feel pretty good about them.
