Milwaukee Tools & Hardware - Others - Recent Questions, Troubleshooting & Support

The only reason a battery powered device slows down is that it's not getting the appropriate voltage from the battery. Your m18 has a lithium-ion battery that when topped off, and for what should be a good long work-period, deliver 18vdc to the motor. Unfortunately, some of the earlier m18 batteries have had some issues and are not fully charging. Some of this is due to improper charging, over heating, storage problems and physical damage.

Milwaukee utilizes a "smart battery" Digital Management System to monitor the "draw" on the battery to keep the user from frying the motor or overtaxing the battery. How hard to you use the tools...perhaps you should trade the stock compact versions for the XC (extra capacity) versions.

You don't say how long you've had these tools, but if you'll go back to the retailer you bought them from, you may be able to get replacement batteries there. Otherwise, check out the Milwaukee website. I think they came out with M18 XC "RED LITHIUM". I think this might be a replacement.

Nonetheless, Milwaukee offers a 2 year warranty on their batteries, so contact your retailer or Milwaukee directly.
