Compact size but big on power. Starts mower first time every time! Would buy again!
Works well in the lawn mower, lots of starting power, excellent reserve power. Fits nicely under the seat of the mower, high value for the price. Recommended. Would buy again if needed.

Working Fine, Happy with the Price
Someone gave me one of those wally world EverStart jump boxes. The 1200 amp all-in-one wonder with the tire pump, light, USB, cig lighter (power ports), and jump-start feature. The battery was dead and they were going to toss it. I cracked it open and found this series of battery in it. So this purchase was to hopefully put the jump box back into service. Always wanted one, but too cheap to justify the cost for something that I 'might' use on occasion. Happy to find this AGM battery and at this price. I don't buy any acid-flooded batteries anymore as no matter the name brand, they all eventually leak at the terminals and corrode the connection. Installed this battery and put the jump box on a charge for a couple of days. The following week I actually had a real-world test for it. My old garden tractor had a flat dead battery in it. Grabbed the jump box and cranked on the garden tractor for awhile to get fuel up to the carb. Then it fired off no problem. A small twin-cylinder gas engine, so not something like a big V-8 or a diesel, but I was impressed with how long this battery did crank, even after the jump box 'low battery' light had come on. I didn't crank it until the battery was flat dead, so do not believe I damaged it, just gave it a workout. Back on the charger, it reached full charge indicated just fine. Also used the built-in air pump to air up one of the front tires on the garden tractor. No problems there either; as expected. Battery is working fine. Hopefully it lasts several years. I'm considering cycling the jump box charging cycle (with a cheap mechanical plug-in timer) as these cheap EverStart jump boxes documentation online gives no details on if it has a built-in float charger or if it is just trying to cram in amps 24/7.

Better than the original battery
Worked and fits into my cen tech 4:1 jumper box and gave it more power than originally had just 4 stars because I don’t know how long it will last

Seems to be a good replacement battery for my jump starter.
I bought this to replace a bad battery in my 8 year old Stanley Fatmax PowerIt 1000amp jump starter. It fits perfectly. The procedure to swap it out wasn’t bad as long as you know you need an Allen wrench to remove the handles. It is rated at 18AH which is 1AH greater than the original battery. It came with a 12.7v charge and after charging it for about 6 hours it had a 13.6v charge. So far, so good! We will see how it performs jump starting dead batteries and how long it lasts. Price was decent, if it performs and lasts at least 3 years.

Works as it should.
This brought life back in to my Schumacher battery jump box with air compressor. It died and would not hold a charge. I removed the battery and tested it only to find out it was bad. This replacement battery was cheaper than buying a new jump box. A few screws to remove the cover and then a few more to remove the battery connections and swap out with this one. The battery seems like the same quality as the original that it replaced.

Great battery.
Battery arrived in great shap, well packaged. I ordered this to replace the OEM battery on my Generag genertor. Exact fit as original. Once installed I hit the starter switch on the generator and it started right up. So, the battery came charged, which was a plus. I will use MIght Max batteries again for other projects, as needed.

La bateria viene excelentemente bien empacada. Lo que evita daños al producto, ya que al ser pesada, en el transporte llegan dañadas. Este no es el caso. La caja si llego con daño, pero la proteccion interna de la pila, la proteje muy bien. Viene precargada y hasta ahora ha durado muy bien la retencion de carga. ver cuanto me dura. Hasta este dia, si la recomiendo, si la volveria a comprar.
