Its Marg Time!!!!

The rebuilt battery worked great. We really put it through its paces this past weekend while camping. It worked flawlessly.


Battery works like new again. Turn around time was only a few days. I am happy with my purchase.

Outstanding service for Coolest Cooler Bat 101

The battery was repaired and sent back to me immediately. I attached it to my Coolest Cooler and it worked as promised. Fastest service I have ever experienced. They are Great.

I bought an aftermarket battery off of the internet and thought I was saving money over getting my battery rebuilt. Boy was I wrong! The aftermarket battery lasted less than 30 days and the joke of a company did not stand behind their product.

I sent my battery to MTO and they fixed it up and sent it back to me. I have been using it for a few months now and all is well. Bottom line is that you should give MTO a chance instead of taking the easy way out with an aftermarket battery.

Get it rebuilt

I purchased an aftermarket replacement online. It failed after two months and the company did not stand behind their product. I called MTO and spoke with a nice man there. He walked me through the ordering process and made me feel important. I sent the battery in and kept my fingers crossed. The next thing you know my battery was back and was working great. Now skeptical, I did not write this review until I used the battery for this whole summer. It has not only worked as it should, it worked better than I ever remember. MTO is the real deal people.
