I've been buying these batteries for years for our alarm systems, UPS, portable equipment and other. Like others they hold their power capacity well if kept charged. Pleased with their performance, will keep buying them.

This promotional set includes two 12V-9AH-F2 sealed lead acid rechargeable batteries, each measuring 5.94 × 2.56 × 3.94 inches. They meet or exceed OEM specifications, are UL-listed, and come brand new from the factory—never refurbished. The quality is solid, the price is competitive, and they’re backed by a one-year warranty for peace of mind.Terminals are clearly marked (Positive + Red, Negative – Black) for easy installation, and compatibility is guaranteed with your 12V-9AH-F2 SLA battery model.When a battery dies, it’s done—just replace it. This set gives you the power you need without the guesswork.

EDIT*** The two new sets of batteries came, this time in 5 days. They wouldn't fit in one of the UPS's without a scary amount force. So I didn't even try it the way they came. I noticed there were some little raised L shaped feet on each corner of the bottoms of each battery. I used an exacto knife and shaved them off. There's no need for those feet inside the CyberPower UPS. They weren't on the originals. They fit more easily after that. I still don't understand why CyberPower made the space in the UPS so small. I had a really hard time removing the original batteries because of that tight fit. These new ones now fit a tiny bit better than the originals. Another thing to note is they are about a quarter of an inch shorter than the original batteries and a tiny bit taller. So when you put them together in pairs, there will be a very tiny little bit of offset in the depth. This is not a problem at all.One other thing to note, the cases and face plates on my CP1500PFCLCD UPS's are a little bit older styled than the current ones that are listed by CyberPower as the same model. The power buttons on mine are above the display and the three settings buttons are below the display. Mine has two USB A ports while the newer one has one USB A and one USB C port. Maybe the battery compartment in the newer styled ones provides a little bit more room than what's in my older styled ones. I do see that other than the USB ports, the specs for the older and newer UPS's are the same and the replacement batteries they sell for them are the same spec as well.Moving on from fit, I have a total of three of these UPS's and I've now replaced all of their old dead batteries with these WEIZE 12V 9Ah batteries. All of the batteries came fully charged (around 12.5 Volts) which is great. I tested their performance after leaving the UPS's plugged into the wall outlets overnight even though they came fully charged. Then I unplugged them from the wall outlets and watched the time remaining. I have plugged into the UPS's (a router in one, a satellite router in another, and the last UPS used to provide backup power for a desktop computer for work, now it's backup for an OLED TV and vSeeBox) Anyway, after unplugging the UPS's from the wall, the time remaining as those appliances ran for a while was perfect based on the wattage draws for each appliance. So the batteries perform perfectly in the UPS's. A+++++Original review*** Delivery took 13 days. But for the quality and price I can wait a few extra days for delivery. Nothing to do with the batteries, but why did CyberPower make the opening for the batteries in the CP1500PFCLCD UPS so frigging tight???????? The original batteries fit extremely tight in the compartment and so did these replacements. The packaging the batteries came in was pretty awesome. Order some and you'll see what I mean. Highly recommended.

Bought in February 2025, installed into a RAZOR Pocket Mod, left them in the garage for 4 months and now they are totally discharged and will not charge at all. Battery charger indicates fault condition. Batteries measure only 1 to 2 volts and will no longer charge. Arkpower graciously reached out and offered to make things right and I really appreciated their efforts. Although this set of batteries didn't work out, their customer service was top notch giving me more confidence in using their products.

Good fit and good price I got my kids ride on car working again

These perform perfectly in my APC BN900M. They're about 1mm shorter in all three dimensions so no issues with fitment. Only had them for 24 hours so hope they last.

Exact fit for my battery backup/surge protector.

UPDATE: Company saw my review and contacted me to replace/refund. Upping stars to reflect great customer service, to make things right.Initial experience: Bought as a replacement for alarm system backup. Matched volts and amps to original battery. Battery rarely used, as system power generally comes from a hardwire. Original battery lasted many years. This Battery Worked great for ~6 months, now many connected sensors are reporting low battery at same time...suggesting its battery not just a bad sensor.
