High Quality Product

Fast turn around time and high quality product. The battery is as good as the OEM product


We had two of these rebuilt for our office last year. The performance is great and the price is reasonable. I even learned from speaking with a customer service representative that removing the battery from the charger once it is charged will extend the overall life of the battery. I never knew!

Better Cells

I am a stickler for details and found that MTO is the only company that is rebuilding these batteries using Panasonic brand cells. Everything one else advise they use a "quality replacement" from China. The MTO rebuilt batteries perform just like brand new battery packs did and I'm not talking about those cheap replacement batteries that can be found online.


The battery it works great now. Run time is very good and I enjoy the reasonable price.


Super fast service and the battery looks and works great. Thank you so much for offering this service for my Demtron batteries!
