ExpertPower EXP1290-12V 9AH SLA AGM Rechargeable 12V Battery for Ride on Toys, APC Backup UPS Battery Replacement, 12 Volt Batteries for Alarm, Replaces UB1290 CP1290 40748, F2 Terminals

I've had my Cyberpower 1500PFCLCD UPS for about 4 years now. I noticed that despite no indicated internal battery problems, the UPS would fail during brownouts or other equipment being turned on. It did not use to do that.To validate, when I have my UPS connected to the wall (with zero loads plugged into it) and I disconnect the AC mains from the UPS, the unit would insta-power off instead of staying on (and running from battery power). This is the classic symptom of a dead internal battery!Anyways, Replacing the battery was straightforward. I picked up a pair of these Expertpower EXP1290's instead of shelling out more than double for the Cyberpower (supposedly) original battery. In reality, the 'original' batteries are Leoch DJW12-9.0's.These batteries arrived about 3/4 charged (~12.74 VOC), in a well protected package. Delivery was quick (2 days).After replacement, the UPS now behaves normally and correctly stays on / runs from battery when it's disconnected. No error messages or other silliness. Also, for what it's worth these terminals on this battery actually fit the internal connectors 'better' than the original. Your milege may vary on that tho, I'm sure it's game of sub-millimeters.While I cant yet confirm if these batteries will last as long as the original; their value is spectacular when compared to the original batteries. Operation looks good. I will update this review in the next few months if anything untowards occurs -- which I doubt. Highly recommended!

It fits, it charged and seems to work.

As expected and received quickly. I purchased several of this brand and I’m happy with them. Recently I received 3 of the 9 AH batteries. The first two were at 12.90 volts and accepted 1.6 ah each to finish charging per the manufacturer instructions. The third was at 12.99 volts and accepted .6 AH to be fully charged. It appears an effort is being made to maintain these and send them out at the very least with a quick charge on them. I do my part fully charging the Expert Power batteries per the recommendations every cycle and these are capable of lasting to expectation especially given the reasonable price.

The batteries in my UPS went bad, finally, so I purchased 2 replacement batteries. These easily slid into my CyberPower CP1500 backup and has been working great.

Fit as expected. Not for the longevity test.

Fit my 6+ year old Cyberpower 1000VA AVR battery backup / UPS perfectly and now as good as new at a fraction of the official replacement cost.

This battery is powering my UPS (Tripp-Lite avr750u Line Interactive 750VA 450W) that is backup powering my PC and monitor. So far the power has gone out twice in 3 months I've had it in use and it has provided me at least enough time to power down my PC properly. Something several batteries in the past failed to do.I can't speak to how long it will maintain this sufficient level of power yet though...

I got this for my TrippLite Omni 650 UPS. It slid perfectly inside and is working well.The original equipment battery, and the first replacement lasted about 4ys each. However, the 2nd replacement only last 2yrs. So now (the 3rd replacement) it's ExpertPower's chance to show how good it is.For now I'm happy with this battery. Because the 2nd replacement had died so early, I was concerned the UPS itself may have been dead. So I was relieved when I installed the ExpertPower, and the UPS came to life, and then passed a "power failure" test.
