> 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 properlyThe 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.

Good quality little battery, comparable to OEM. Highly recommended.

Used it here and there during the last few weeks, so far I'm happy.

Ive used the battery just like an OEM Milwaukee. I cannot really tell the difference between an OEM battery which makes this deal even better. So far no one else has noticed this is a good quality battery without being so expensive.

This is a good fit for my pin nailer, works fine, but is a little harder to take out than the OEM ones. It last a long time in my nailer, have not had a chance to try it in heavy duty applications, but so far am happy with it.

We needed a new battery for our driver set in our house and we chose this one. This battery way less expensive than original battery. It has descent battery life and fit well. It may not perform 100% like an OEM battery, but it’s not far from it. Still good quality, great performance, and for less money.

Bull Tech's M12 battery is a decent 3rd party battery for Milwaukee M12 tools. Not bad, but not great. The plastic latches feel a little flimsier than my Milwaukee batteries, but not enough that it didn't lock into place with my tools, nor did they get shaken loose. The weight of the battery and performance time in my M12 vacuum feels more like a OEM 1.5Ah battery than the 2.5 Ah advertised but that type of mislabeling is unfortunately pretty common in 3rd party batteries. While I'm still a bit cautious about 3rd party batteries, I didn't see anything that raised concerns since I didn't get any errors in the tools or chargers that I tested it with.

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.
