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.

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).

I have a CyberPower 1500VAC Battery Backup that began throwing the E02 error. This error is indicative of the current batteries not holding the appropriate voltage. Upon investigating, these batteries appeared to be direct replacement and so I went for it. These arrived exactly as advertized and were, in fact, exact replacements for the ones I removed from my CyberPower. I tested the voltage of each prior to installation and they were both showing about 14v. Knowing the voltage was good, I quickly got them installed and powered up the device. The batteries arrived with an approximate state of charge around 90%. I have been running these for just over a week without any issues. This was a very simple and straightforward fix with a quality replacement at a fair price. I have chosen to rate this product 5 stars. It has met my expectations for the price and I would completely recommend. Although I haven't had them for very long, I have monitoried them every day and they are holding the charge as expected. Due to my immediate need for the replacement batteries, I didn't spend much time reading previous reviews, but these are definitely worth reviewing. They were exactly what I was looking for and working exactly as advertised. Criteria for Stars: 1 - Total rip off, doesn't perform basic advertised functions or not product advertised. I would likely RETURN and would NEVER recommend. 2 - Not worth the money. Performs some of the basic advertised functions, but likely not all, and ultimately was deemed as not providing enough value for the money spent. I would not buy again, and would likely not recommend unless the buyer had a very specific use case. 3 - It performs the basic functions as advertised, and has some usefulness at the price point, but doesn't work for all of the reasons I purchased. I would likely not buy again, and would only recommend if buyer understood usefulness limitations. 4 - It performs most all of the features I purchased it for, but has limitations. I would likely buy again and would recommend. 5 - Completely as advertised and likely exceeded expectations. Is if high quality and well shipped. I would totally buy again and recommend.
