> BULL-TECH 12V 48-11-2425 2.5 AH for Milwaukee m12 Battery,Compatible with All Power 12V Milwaukee Power+ Tools (~$34) The Good: + Good Wh rating, seems accurate + Fit and finish fits tools properly The Bad: Nothing I found. I ordered these (and several other brands) and tested in my 12V drills and driver, and they work great for me. Still holding charge, no problems. Occasional heavy use where I go through an entire battery, but generally light use every day or two. I haven't experienced any of the halting or overheating issues others have seen on various similar brands with my drills or drivers. ... show more

    • Didn't last after 2 uses.
Style: 12V BATTERY
Had for 6 months. Used only twice but no longer holds a charge. Did not do anything to damage or mishandle the battery. Used on 3 different chargers and none of them could charge the battery. Ordered from a different company and those batteries did charge and work. Unreliable.

    • not a perfect fit
Style: 12V BATTERY
battery life is not quite identical to the original and the fit into the tool is sub-par. The tabs do not lock correctly. The battery is able to be removed without squeezing the tabs. Safety concern and frustrating.

This is a decent battery and a good value. It fits snugly in all 3 of the M12 tools I use: a rotary (Dremel type) tool, a one-handed Sawzall, and an older impact driver (all brushed tools). It charges the same as the stock batteries. I was surprised at how much this battery weighs, 176 grams, which is a lot more than all of my other generics. In fact, it weighs almost as much as the name branded 2.0Ah battery (179 grams). Usually this added weight means a better battery. In terms of torque and runtime, this battery is closer to the name brand 1.5Ah battery. On the rotary tool, this is only noticeable when bearing down on cutting/grinding. On the Sawzall, it's really tough to tell which is better. And, the stock battery on the impact driver can get a couple extra turns over this battery. ... show more
