NPP HR1234W - 12V 9Ah Rechargeable AGM Battery, 12 Volt 204Watts 34Watts/Cell, Sealed Lead Acid F2 Terminals, UPS Batteries Replace NS1250 Alarm Emergency Systems Flame Retardant UPS Battery

These fit perfectly in some APC and CyberPower UPS units that require a very narrow width replacement battery. Check your size before ordering for a correct fit. The UPS units I own claimed there were no user replaceable batteries but these worked like a charm and were way cheaper than at my local battery store. The price keeps creeping up so only time will tell if these batteries will remain a good deal.

Perfect fit for a CP825AVRLCD purchased in 2012. Plug & Play! I had it plugged in & charging for 24 hours before using; even though it came with 80% charge already. A few months of use now & no problems.

This NPP model battery has performed well in multiple UPS (Battery Backups) lasting longer than expected at 5 years in CyberPower UPS as replacement batteries.

Bought this to test against the batteries the German manufacturer of race timing equipment uses as OEM. The batteries they source don't provide the duration of runtime claimed, so I have been trying different Amazon finds. Mighty Max only last 3-4 months. This one is 3 months of weekend only use. Tried it today and it only powered the device for 50-55 minutes.If this is supposed to be a 15amp/hour battery, it should be able to do 5 hours easily as the draw on the battery is half of what it could be. (There are a maximum of 8 RFID antenna/receivers possible, and only powered 4).There is no way this battery is meeting the specifications claimed or I wouldn't be having to use an Eco flow battery to keep it powered.We just did a 1-antenna test to see when it would die. It lasted 3hr50min. Now, it won't go an hour with 4 antennas powered. And to be honest, there isn't that much draw to create radio waves. If people use these for motors to kove mass, they'll surely be stranded.

This battery works well for my emergency charger. A great value for the price.

I have bought these many times. Most UPS batteries last about 2 years. I replace the batteries to keep costs down. These 12V 9 Amp HR batteries keep my computers running during quick power surges and brown out. But more often it is a tripped breaker that these save us from data loss, epically during the winter when users are running space heaters at their desks. A space heater and laser printer will trip the breaker almost every time.

I have not had the unit for long so cannot attest to longevity.It was NOT easy to install but that was because of the lack of room in the UPS battery alcove I was installing it in.That being said, its been a work horse since I started using it. We have lost power a couple times and its kept my computer, my Sister's computer, monitors, modem/router, desk light and transfer switch all powered up.We asked for an hour of use and it gave us 2 before power was restored.

No date codes! Was disappointed when I opened the package to see this. I hope the company honors its warranty! Will update if anything happens
