    • High-performance battery.
Great battery! Holds a charge well and powers my tools for a long time. Fits perfectly in all my M18 Milwaukee tools and charges quickly. Definitely reliable for heavy use.

Very good battery at a good price, has a long runtime, will charge in about an hour, fits all tools, and is not heavy despite its size.

    • Working well despite the heavy weight and high cost.
Working well despite the heavy weight and high cost. Will have to wait to purchase any more of these batteries until the price drops. We prefer do these OEM to the generic brands.

    • It has the power!
SO much stronger than the smaller batteries that come with the drill and impact wrench! Only used a couple of times with the M18 120/500CFM leaf blower but So far, so good.
