NPP HR1251W (F2, 4Pcs) 612Watts12V 51Watt/Cell AGM Sealed Lead Acid High Rate Battery, Replace 12V 14Ah, 15Ah Flame Retardant UPS Battery for Fish Finder, Scooter, Security System and Solar System

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.

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.

Finally a set of correct fit batteries with a decent capacity. Made the battery swap easy. Have used them for about a month, scooter runs great and has better range than before with the OEM 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.

EDIT1. Positive Comments apply to Seller and productHowever :Second purchase never came about !Got full cooperation from vender, who sent me a Refund, because item was out stock.Item shows Delayed, ? ?1. Sturdy built2 Exact same size as originalRated at 9 AH .. best that I could find3. Tight fit due to Device design Same as originalArrived Fully Charged .. 12.85 Volts

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.

The original battery in my CyberPower 850PFCLCD died after serving 12 years. It was a B.B. battery, HR1234W.I bought this battery as a replacement and it was perfect match. Not that difficult to remove the old battery and install the new one.

Has F1 size male connectors on battery but my UPS has F2 size female connectors. No problem. An F2 female can fit over a F1 male or you can buy F1 to F2 adapers. Just make sure the battery dimensions will fit in the space available and that you are selecting the correct voltage for your replacement.
