I purchased and received 2 batteries for my disabled scooter. Needed help from their customer service who were absolutely professional and extremely helpful in every way. I won't hesitate ordering from them again.

I have a 20+ year old Diehard Portable Jump Starter 1150 that has been a great product until this year when i discovered the original battery had "outlived it's useful life".I thought it was time to give it up until I Googled the battery and to my pleasant surprise Mighty Max has a direct replacement and I am now back in business!!!Thank you so much for providing Life Support for this Old Friend!

Battery is great. Fit our ADT system exact and installed perfectly. A+++

Works as expected for mobile chair

Ordered from Duromax to replace a defective battery
