    Battery was new (manufactured a couple months ago), and in excellent cosmetic and working condition.

    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.

Mighty Max Battery
Based on 3474 reviews
Arrived quickly. Even got a sticker with it.
Solid looking battery, came well packaged. Have used their battery before for my lawnmower and now looking forward to see how it lasts in my snowmobile.
I can't believe it less than 48hrs since I ordered from Walmart and it's in the machine. What more can I say except great price.
Thanks Larry
Item as described and perfect fit and arrived on time
Battery arrived in a good shape package strait to my door steps
Arrived just in time to power my generator here in the cold Maine winters. Excellent service!
Arrived quickly from WALMART.COM. Perfect size and proper placement in my generator. Installation was easy. Generator fired right up. Battery came fully charged.
New battery. Ready for cold weather!
So far these Might Max batteries are good but it’s only the first day and they were on charge for 12 hrs. I’ll have to come back and do an update at some point in time. Ordered them on Amazon and got them the next day. I was encouraged by Mighty Max to make this google review and post pictures to extend my warranty for 3 months but there is no way to post pictures 🤣🤣🤣 It’s been a few months and I was able to go back and edit, so here is a video I made, the rest of the photos I have deleted. Batteries are still going strong. Update 12-11-2025
They arrived within 2 days of ordering them packaging was really good I haven't put them in my MX350 yet I hit them with my multi meter fresh out of the box and got 12.4v on both batteries so that is good
