ExpertPower ® 12v 9ah Sealed Lead Acid Battery with F2 Terminals (.250") / 4 Pack

Good quality, good price, and fast shipping!

Have ordered from other companies, however ExpertPower seems to be the most consistent in delivering what I order. Proper terminal size and specs. Batteries seem to be okay, to soon to know longevity however, initial use is positive so far.

I’ve ordered these in the past and they are a great value when bought in a bundle of four.

The order arrived a day early, which was excellent service. They were also already charged and easily installed. So far there haven't been any issues. I rated longevity as a 4 because I don't know how long the batteries will actually last. Although they manufacturer indicate 5-years, most batteries don't last their lifetime.

Bought the 4 pack to replace the batteries in two Cyberpower CP1500PFCLCD UPS units. I was able to pull out the old batteries, then moving the wiring over to the new batteries. I added a little packing tape to keep everything together, then I was able to slide the two new batteries back inside the UPS. I'm getting an excellent run time on these new batteries. Also, the batteries I received were well packaged and arrived priority via USPS. I will be ordering more of these batteries in the future. Thanks ExpertPower!

Came fast, almost fully charge right out of the box. Fit Cyberpower 1500VAs UPSs and APC Backups ES-550. Probably fits other Cyberpower and APC devices, but I can only verify these. I have two different Cyberpower 1500VAs, both are duel battery. One stacks the batteries the other mates them horizontally with a plastic insert between them. These batteries fit both versions of the Cyberpower 1500VA. Sweet. Can't say how long they will last, but if I remember a year or so from now, I'll update this comment. Its (7/30/2019).

These are for my APC Rs-1300 UPS. 1st batteries had charge Worked instantly. 2nd set had zero charge battery took @ 30 min to start taking a charge. I will update when it takes full charge. Fast Shipping well packed. Overnight 1 st took a full charge @ 800 min backup , 2nd set 275 minutes backup power - I switched batteries between units and same batteries are running low - contacted vendor

I bought these for my 2 CyberPower 1500 battery BackUPS. Each takes 2 batteries, so the 4 pack was perfect. I'm guessing it's a fairly standard size, they fit perfectly. Once installed my UPS went to 100% available battery power. I can't speak to longevity as I just installed them. After I have a power failure I'll update this review if for any reason they don't live up to my 5 Star rating.Update: The batteries lasted me about 2.5 years before I had to replace them. I replaced them with these same batteries.
