Good job

I had a pleasureable experience with having my Standard Horizon CN350 battery pack serviced by MTO. The turn-around time was short and the quality of the battery that I received back has been wonderful thus far.

Pro Job

Looks and works great!

Nicely done

These people are true pros at what they are doing. The battery works like new and still looks like new as well.

Amazing service

The CNB350 batteries that MTO Battery rebuilt for me are working like new again. I was very surprised when they came back to me because I could not even tell they opened them up. Great job!
