ExpertPower 12V 7Ah - SLA Rechargeable 12V Battery for Ride-On Toys, Alarm System, UPS, EPS, Feeder, Exit Sign, Small 12 Volt Battery for Kids Car, Sealed Lead Acid Fire Alarm Batteries

I purchased this to replace a dead battery in a universal power supply (UPS) backup, and this is actually the second time I’ve used this specific ExpertPower model. I bought my first one over a year ago to fix a different power supply unit, and it has been rock solid ever since. So, when a second UPS recently failed on me, I didn't hesitate to order this battery again. It was a perfect drop-in fit (standard F2 terminals made it easy), charged up quickly, and is working exactly as expected. It’s a much better value than replacing the entire UPS unit. I've had very good luck with these batteries for reviving old equipment and highly recommend them.

TOS is a really good battery and works great it charger fast it is safety it is not a lot of weight the design is cool

Last week, in August 2025, I replaced this battery which I bought in 2020. My ups started beeping indicating a battery failure, and installing a new battery since it, confirming it was the battery. Given that it lasted 5 years, I'd say it's not bad for the price. I don't know how many times I may have had a power failure that requires ups power, but probably a few, some shorter some longer. I'm now using lifepo batteries instead, stove they are much lighter and suppressed to have higher capacities, but haven't had one for 5 years yet to compare durability. This one has proven to work fine for 5 years of daily use, so I think it's a good buy if you are want to use lead acid batteries.

It works to power on but size is too big and Does not fit razor Black Label E100 electric scooter

Great replace battery , the little car runs like new now !

Came packaged good, stays charged, easy to replace old one just plug in. Not heavy at all, came with all safety papers and everything

Your mileage can vary with these depending on the application, but I can usually get 4-5 years from one of these on a UPS for home computers and NAS drives. Never had a bad one until I DIDN'T buy an ExpertPower 2 years ago. This replaced it, so I expect a good 4 years of service out of it. Reputable name in SLA batteries. Just remember whether you have F1 or F2 terminals to connect to it as the width of your connector matters. (F1=smaller; F2=wider)

Works well. However, just a bit too wide to fit behind the battery cover in a CyberPower ST425. My workaround was zip-tying in place. My advice: Measure first! DUH!

Very happy with this battery bought it for my fishfinder works great no complaints sorry no picture. It’s at the lake right now waiting for the ice to come so I can go ice fishing and catch more fish.

Quality is good and meet purpose

The product was shipped quickly and was easy to install.
