577661 Festool Lithium Battery Rebuild Service

577661 Festool® 18V Lithium Battery Rebuild Service


Rebuild Service for a Festool® 577661 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. Send your 577661 battery to us and let us make it work as well as new. Our trained technicians work on Festool® brand batteries each day. We rebuild almost all types of Festool® brand batteries including those used in diagnostic equipment. Don't wait any longer. Send your 577661 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. 

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

Note: This is a rebuild service and not an attempt to sell a new or aftermarket battery pack. With this service, you must send your battery to us to be repaired.
