ExpertPower 12v 9ah Sealed Lead Acid Battery with F2 Terminals (.250")/2 Pack

I've had my Cyberpower 1500PFCLCD UPS for about 4 years now. I noticed that despite no indicated internal battery problems, the UPS would fail during brownouts or other equipment being turned on. It did not use to do that. To validate, when I have my UPS connected to the wall (with zero loads plugged into it) and I disconnect the AC mains from the UPS, the unit would insta-power off instead of staying on (and running from battery power). This is the classic symptom of a dead internal battery! Anyways, Replacing the battery was straightforward. I picked up a pair of these Expertpower EXP1290's instead of shelling out more than double for the Cyberpower (supposedly) original battery. In reality, the 'original' batteries are Leoch DJW12-9.0's. These batteries arrived about 3/4 charged (~12.74 VOC), in a well protected package. Delivery was quick (2 days). After replacement, the UPS now behaves normally and correctly stays on / runs from battery when it's disconnected. No error messages or other silliness. Also, for what it's worth these terminals on this battery actually fit the internal connectors 'better' than the original. Your milege may vary on that tho, I'm sure it's game of sub-millimeters. While I cant yet confirm if these batteries will last as long as the original; their value is spectacular when compared to the original batteries. Operation looks good. I will update this review in the next few months if anything untowards occurs -- which I doubt. Highly recommended!

I bought this 2-pack of ExpertPower 12V 9Ah SLA AGM batteries as replacements for my home UPS system, and they've performed flawlessly so far. The fit was exact, and the F2 fast-on terminals made installation quick and hassle-free — literally plug and play. Each battery arrived well-packaged, fully charged, and in perfect condition. I appreciate the AGM design — no spills, no maintenance, and very clean to handle. The non-conductive ABS casing feels durable and solid, and the batteries hold their charge as expected, even under moderate load. I also tested one in a gate opener system, and it’s running like new again. These are definitely versatile and dependable for a range of 12V applications — from UPS backup to scooters or alarm systems. For the price and quality, this is a great value 2-pack, and I’d absolutely buy again when it’s time to replace more batteries.

Great battery, good price.

Las baterías llegaron en el tiempo estimado, bien empacadas y funcionan bien.

It's been in my UPS for about a year without trouble. So far, so good. I've read some people complaining about the connectors being too small, but i didn't have any problems making my connections (of course, you have to make sure you don't attach your cable connectors upside-down).
