Rebuild Service for a Milwaukee® 48-11-1890 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. Our trained technicians work on Milwaukee® brand batteries each day. Don't wait any longer. Send your 48-11-1890 battery pack to us for repair today!

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. This specific battery is prone to going red flashing partway through the charging cycle. This is due to the PCB getting warm and is rarely related to the battery itself being hot. When this occurs, either leave the battery in the charger or remove it and allow the PCB to cool before charging again. The battery will eventually charge fully using either method.

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