Great Replacement Battery
I purchased the Mighty Max ML5-12 to replace the original battery in my equipment, and it fit perfectly right out of the box. Installation was quick and easy, and the battery came fully charged and ready to go. It holds a solid charge, delivers consistent power, and has been very reliable so far. I’ve used it in both warm and cooler conditions without any performance issues. The sealed AGM design is a big plus—no leaks, no maintenance, just dependable power. For the price, this battery is an excellent value compared to other brands. If you’re looking for a dependable 12V 5Ah replacement battery, this one does exactly what it’s supposed to do. I would definitely buy it again. ✔ Easy installation ✔ Strong, steady power ✔ Great value for the money Highly recommended.

Reasonably Priced and Works Great!
This was a perfect fit for my APC Back-UPS 425. Why toss a perfectly good UPS, when, for a fraction of the cost of a new UPS, you can replace the battery and have a like new UPS? U-Tube videos provided all the instructions I needed to quickly change out the old battery with this Mighty Max ML5-12-12 volt battery. I've used Mighty Max batteries in a number of applications in the past and have been happy with the fair cost and performance of this brand. Glad it is available on Amazon. Local salvage yard will pay me to dispose of the old battery, so you can't go wrong with this one!

Works as it should
Got this for a garden sprayer that we outfitted to use as a portable waterfed for window cleaning. Old battery wasn't holding a charge after six years of off and on use. Battery is exactly as described. It was easy to install. Works just like my old one when it was new. Definitely plan to order again whenever we need any more.

Excellent replacement for Crazy Cart Shift 2
I used this to replace the battery on a crazy cart shift 2. I cut the connector off the old battery and connected to this new one with solder. Worked instantly out of the box and fit perfectly.

Only lasted about 3 years and then side split open.
Used in Chamberlain garage door opener. Battery seemed to do everything it was supposed to and fit perfectly. It failed after just under 3 years. Side split open. Guess I couldn't expect more for the price.

Just What Was Needed
Needed one of these for use with a Mighty Max gate opener. This one was just the right size for my outdoor enclosure. Easy to install and was a great battery replacement for my other battery. Very satisfied.

Works in APC B-UPS 425
This battery arrived quickly in perfect condition. The description didn't specifically say it would fit in my APC Back-UPS 425, but it fit perfectly, was easy to install and as you can see in the photo got a green operating light when I turned the unit on. I just installed it today, but I will report back if any problems occur.

Le cambié la batería a un viejo no break koblez que solo usaba de regulador solamente desde hace unos años y quedó como nuevo, la batería original era de 4.5Ah y la nueva de 5Ah, leí que no hay problema y después de 2 meses del cambio funciona excelente, llegó rápido y muy bien empacada

Installed it today no issues. Worked as a perfect replacement for my craftsman 1/2hp belt drive garage opener. Hoping it lasts as long as the original.
