## Questions & Answers

**Q: Is this a genuine Milwaukee product? Some are saying it is not.**
A: Yes it is.  Our product are 100% brand new and are genuine Milwaukee battery.  We buy in bulk quantity so sometimes it does not come in original packaging.  But I can assure you they are 100% brand new and are from Milwaukee.

**Q: Does this work for a Milwaukee lantern? If so, how long will it last before before it needs to be charged?**
A: (Yes and that depends) Yes it works with 2 types of M12 lights (1. M12 LED Stick Light 2351-20) and (2. M12 LED Lantern/Flood Light 2362-20) Now you said Lantern so i'm guessing you mean the 2362-20 which has Four Light Settings: High, Medium, Low, Strobe. Run times are base on the XC 4.0 Extended Capacity Battery Pack. Low 67 Lumens 67 Hrs Run Time, Medium 200 Lumens 15 Hrs Run Time and High 400 Lumens 8 Hrs Run Time. Hope this Helps Good Luck. :)

**Q: Will this battery really increase the power of my tools? Specifically the M12 5/8" cordless circular saw.**
A: Under heavy load yes the larger capacity allows the tool to draw more amperage resulting in slightly more power without stalling out the blade.

**Q: Don't this battery fits on milwaukee mlw255721 3/8 inch m12 fuel ratchet auto kit ?**
A: As far as I know, all of the M12 batteries are interchangeable. We have 1 tool with 3 different size batteries. We use this tool in our business and have run it hard for over a year with no problems...
