KB 540-06 Kobalt 40V Lithium Battery Rebuild Service (KB540-06)

KB 540-06 Kobalt 40V 5.0Ah Lithium Battery Rebuild Service (KB540-06)


Rebuild Service for a Kobalt KB 540-06 battery pack. For the cost of this service, we will open your battery pack, replace all cells, 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 that of a brand new battery from the OEM but at a fraction of the cost. Send your Kobalt KB 540-06 battery to us and let us make it work as well as new. Our trained technicians work on Kobalt brand batteries each day. We rebuild almost all types of Kobalt brand batteries so if you cannot find the one you need please contact us. Don't wait any longer. Send your KB 540-06 battery pack in 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.

Kobalt 40V Battery

MTO Battery rebuilt my Kobalt KB 540-06 battery on 2/2022. The battery was used all last season and was used fairly hard in the fall and this spring. I have experienced great run times and the battery stored like a champ over the winter. The quality of the service that this company provides is truly great.
