WEIZE 12V 9AH Battery Sealed Lead Acid Battery with F2 Terminals Rechargeable Replaces 12 Volt 8AH 10AH for

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. Read more

I bought a pair for a CyberPower UPS in April 2025. As of October 2025 the UPS is failing it's self battery test.. Normally these last a couple years.. I've certainly never had to replace them in the same year -- update: I replaced the batteries and the UPS is still failing it's self-test -- so it is the UPS. These Weize batteries still have 13v on them.. I should have checked that.. Read more

Although not designed for an APC UPS, that's where I use them, in series to produce 24V. The APC BR1500G has a port to add a supplemental battery pack, but at over $200 it can be a little expensive. So I bought this two battery pack, used 10 gauge to make three cables with F2 terminals to connect the batteries in series and then connected them to the back of the APC BR1500G, where the battery pack is supposed to be hooked up. It works like a charm and much less expensive than purchasing the APC External Battery Pack, BR24BPG. The APC BR1500G maintain the battery pack charge, so there's no need for an external charger.

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. Read more

I bought 2 of these batteries 2 years and five months ago. Here is a report on how they performed over time in a UPC. They performed well for about 1.5 years with the run time dropping off quickly after 1.5 years. At some point in the last 7-8 months they started leaking and corroding the terminals. When it became apparent they were not functional when the electricity went off recently I opened my UPC up and found a mess. They leaked! I had a lot of acid damage to clean up and had to replace some wires and 3 of the terminals corroded, 2 of them corroded off. Just a nightmare. After hours of repair I am installing a different brand AGM battery. I do not recommend. Not very good performance and I had to deal with damage. Read more

1 day after install, product fit perfect in my sons Razer E300 Scooter. Install was easy, basically drop in, but I did have to cut the wires and crimp new terminals onto the wires. This is due to the factory installation method. It only added about 2 extra minutes. I'll let you know if the batteries fail early with a follow up if the become a problem. Read more

The battery are good and well priced. So far so good. Read more
