Fast ship, sturdy packaging. Great fit, brought booster pack back to life.
Delivery was prompt and the packaging is outstanding. This battery starts my Westinghouse generator quickly. I have a few and I like them over the OEM batteries.
Next day arrived. Easy to install.
Used in my wood chipper
Gel battery for my Kawasaki Mule
Ordered a 3-pack of 12v 10ah batteries for my Black and Decker lawn mower. Batteries were a perfect size replacement, requiring no modification to the housing. Fully charged and ready to go.
Battery works great
I originally ordered the wrong battery. I asked to cancel the item and expected a hard time…. I was very nicely informed that my incorrect order was cancelled.
Then I ordered the correct battery ( pretty late in the day). I expected delivery to be at least 2 days . It was delivered in less than 24 hours. Great customer service and fast delivery. It was a nice experience, I would recommend Mighty Max Battery to anyone looking for a battery….. forgot to mention the great price, too.
The battery is a perfect fit. Here is a picture of it in the HONDA generator it now calls home.
Quick delivery
Arrived quickly charged. Working fine so far
