Charging Recommendations

1. Always ensure that the battery is not hot and is at room temperature before charging.

2. Once charged, remove the battery from the charger. Do not store the battery on the charger for extended periods of time. Please note that storing a battery in a charger that is not plugged into the wall, can potentially cause the battery to drain back into the charger. This was more common with older chargers and we have also noted it in some newer chargers.

3. It is recommended to not store the battery on the device when not in use. Storing the battery separately removes the possibility of the device slowly draining the battery. 

4. If you have not used the battery for 2-3 months, we would recommend recharging the battery and if possible, use them. This helps maintain their health.

5. Lastly, be sure to store your battery in a dry environment. If possible, avoid temperatures below freezing and above 110F to maximize battery life.

This is a battery rebuild service!

You must ship YOUR battery to us to be repaired. We DO NOT sell new, used rebuilt, or aftermarket battery packs.


Rebuild Service for a DeWalt® DCB120 battery pack. For the cost of this service, we will open your battery pack, replace all cells, test, and reassemble. Cases, connectors, and circuit boards are re-used and are not replaced or serviced. The performance of our battery packs is equal to or better than that of a brand new battery from the OEM but at a fraction of the cost. Send your DCB120 battery to us and let us make it work as well as new. Our trained technicians work on DeWalt® brand batteries each day. Don't wait any longer. Send your DCB120 battery pack to us for repair today!

Upgraded rebuild capacity to 2.5Ah

Note: When we are rebuilding your battery, if your circuit board is found to be defective, we will contact you. At that time we will provide you with the option of sending us another battery or we can refund you for the rebuild service. The old cells are removed and recycled prior to circuit board testing and cannot be shipped back to you. 

Orders containing lithium batteries will ship by ground only regardless of the shipping method chosen.

DCB120 Battery Rebuild Service

Excellent service in every way: quality of product/repair, communication, service & shipping. I spoke directly to the owner at a time of local community stress. Even though my order was very small on the scale of what MTO is capable, the owner talked to me like a valuable customer. The battery rebuilds I got have proven to be great. I couldn’t be happier.

Huge difference

I don't know exactly how much better these batteries are but I would swear that they are about twice the run time of the original 12V max batteries that I had from DeWalt. You all should update your site to state that these are way better than new. You are underselling yourself!!

Better than new

The DeWalt batteries that MTO built last much longer per charge than the new batteries I purchased around the same time. They are powerful and seem to be holding up to hard use.

Great service

DCB120 battery is working better then new. Thanks MTO for great service.

Works Great!

I had 6 of these batteries done. Turnaround time was quick and the batteries run at least 30% longer than before.
