    Batteries were an *almost* drop in replacement for the hr1234w. However, the description says the terminals are F2. They are actually F1 and were very loose.

    Replacement battery for a UPS that had quit working. It matched the original battery for size, terminal layouts, and a little more capacity. Installed in about 2 minutes and has been working without an issue.

    exact fit for replacement of OEM Cyberpower batteries, though the clips were a bit smaller everything is snug and working well, time will tell if these really last the full year they are rated, but for now no complaints

    Great replacement battery for my CyberPower 825AVR. The connection points on this battery are slightly smaller than the connection points on my old battery but they still connected just fine with the CyberPower 825AVR and now I’m back up and running!

    Good price and does exactly what it is supposed to do. What more can I say since I don’t know how long it will last. Seems heavy so it probably has a decent number of lead plates which is the biggest factor in longevity for a lead acid battery.

Well packaged, battery looks to be good quality, will install on the weekend and update over time. Got it on Amazon.
Arrived quickly, week package. Week put them to use quickly in Spain.
Love my monster music box and my 1st battery lasted a long time.
Had a Legend battery bought in January of 2024 that went bad wouldn’t start under a load. I have a 2005 Volvo xc90 V8 so the battery cranking is important. Ordered the Mighty Max through Amazon I was overnighted to me , delivered to my doorstep. Recharged all ready to go drop in and start, beautiful! Has a 3 year warranty with options to extend that warranty. How great is that!
The batteries were packaged well, and arrived looking good. Now we need to hook them up.
Came fast and packaged well. Even came with a sticker. Fun stuff
Excellent battery replacement for Razor Electric bikes!

Very well packaged and.arrived as promised
