We offer a 12 month warranty on all of our battery packs. In addition, we rebuild all brands.

Five star rating is for the battery pack itself. Top notch. Impeccable quality. Couldn’t be happier with that. A warning to anyone attempting to do this repair on the “XR” old style battery. The description says, “Battery pack with one screw in the center.” However, there is MUCH more to getting these cases open. The entire perimeter is glued, so unless you are really good at disassembling glued electronics, I would recommend sending your pack in for professional repair. I am not good at this, but I got it done with a heat gun and utility/x-acto knife. It’s not perfect, but I didn’t butcher it too bad. If I had known in advance these batteries don’t come apart as easily as the ones in the “how-to” video, I would’ve sent my battery in for professional repair.
