B&B BP3-12 Replacement Length 5.28 in. Width 2.64 in. Height 2.36 in 12V 3.4Ah UPS Battery Beiter DC Power«

My old Cyberpower UPS wasn't working. Replacing the battery restored it to working order. I would have though that a bad battery would have just reduced the capacity of the UPS. But in my case the bad battery completely disabled the plugs on the "battery" side. Nice to have it working again. Much cheaper than buying a new unit.

Little bit larger so hardtofit

This battery fit perfectly and works well. It saved me a considerable amount of money by not having to buy a new UPS. It helps to have a basic knowledge of electrical equipment to remove the old backup battery, but as long as it is unplugged and safe to work on it should be no problem to change.

Maybe it will start the mower once on single charge, then I have to charge it again

Was a good buy. And easy to install in my mower

Installed battery on my mower, turned the key, and was off and running.

I didn't really want to buy something with only one customer review, but thought I would take my chances and return it if needed. The price was right. I got it today and my mower started right up. It says it has a 3-5 yr life. We will see.

Works fine. But I was doubled shipped! ????
