Milwaukee replacement battery packs built by Bluff Valley Battery. Our packs are built per order, so you know you get a fresh pack, not one sitting on a shelf for 6 months. We use only high quality 1.2 Volt, 2200 mAh NiCd cells or 2600 mAh, 3000 mAh, 3400 mAh, or 3800 mAh 1.2 Volt NiMh cells. After assembly, we test, inspect and charge the battery pack so you can bring your Milwaukee tool back to life. We offer a 12-month warranty on all of our battery packs. We do all models of Milwaukee Tool Batteries. In addition, we rebuild all brands. Just send us your old battery pack (we recycle all batteries) and we will rebuild it and send it back out to you in 5 to 7 days.
