ML7-12 - 12 VOLT 7.2 AH SLA BATTERY - Mighty Max Battery brand product, black

My GE Concord 4 alarm was beeping, and I couldn't figure out why. I decided to change out my backup battery with this fresh one. Lo and behold, the beeping has stopped. Works great!

I searched Amazon for a replacement battery for my CyberPower LE850G UPS and it took me to this battery. Specs looked correct, but when the battery showed up I realized the terminals are too small on it. This battery has F1 terminals on it and the CyberPower LE850G wiring is for a F2 terminals. If you need the F2 version, then look up the Mighty Max ML7-12F2. Alternatively, you can purchase F1/F2 adapters, but I'd rather have the correct battery/terminal and avoid using adapters.

Threw it in my home alarm panel, plug and play have a nice day. Will be buying a second for my other panel.Haven't tested extensively for capacity or duration to backup power my panel but 99% of the time it only needs to be for less than 10 seconds and so far it's plenty capable of that.Nothing to report on weight, it's as heavy as you'd expect a battery this size to be. Value for the money seems fair.

Good value.

We use these professionally to rebuild data center battery packs for APC Uninterruptable Power Supllies. We've purchased over 100 in the last three years.They equal the OEM specs and are outlasting the APC factory units. On average we're getting about three years out of them before they need replacement, a year longer than the OEM batteries. That alone makes them a bargain.FWIW the gel cell version of this battery (as opposed to this model, which is SLA, sealed lead acid) is also offered by Mighty Max on Amazon. The gel cell's a little better if your application requires frequent deep discharge. For UPS battery packs, alarm systems, etc. this SLA version is fine.If they are shipped direct instead of by Amazon, you can expect fast delivery. The Mighty Max warehouse usually ships the same, or next day and they are packaged well.

It works great in my Electric gate opener, better than the original ones. It has lasted longer than I thought it would.

Nice battery works great on my kids car

The good: They're cheap and they fit my Verizon FIOS system perfectly.The bad: They don't last very long. Purchased mine in October 2022 and it only lasted until January 2025 (2 years 3 months). This compares to about 8 years of life from the original battery Verizon installed. Sure, Verizon will come install a new one but it's about ten times as expensive.What went wrong: Per my battery tester, voltage and amp hours both measure OK but the internal resistance is now very very high for an AGM battery at about 47 mOhms (an AGM battery can be as low as 3 mOhms.)
