Really extends time in use.

These batteries have lasted just as long as the Milwaukee 6.0 batteries. The only downside I have found is if you are very aggressive with the drain they will not want to recharge. I made the mistake once but was able to bring the battery back to life by giving it some charge from a different battery. Overall. For the price point these can’t get beat!! I use my M12 products every day and so far only had charged 1 of the 4 that I have bought.

I've owned two of these batteries for just over a year now, and I work in a trade. My tools do get pretty beat up, and sometimes they do get dropped. Yesterday, as of writing this review, my charger refused to charge one of these batteries. This has lead me to open the battery casing to find the issue, as most likely it was a lost connection.Sure enough, I find a wire that has detached from it's solder point, and as seen, there's really not much solder there. I've added new solder to all of the connections I could get to, and added hot glue over the top to keep them from coming apart again.All said and done, the consumer should not be responsible for disassembling these battery packs to perform any repair, especially for something so easily prevented. This type of lithium battery is potentially dangerous if mishandled. One small glob of glue Vanon, please take notes.For lightweight usage, probably won't be an issue for the average person. But anyone who uses their 12v tools on a daily basis, will likely encounter this issue eventually. If you're comfortable with handling these types of batteries, or know an electronic hobbyist, get some hot glue ready after you buy.

This battery gives my Milwaukee impact driver more power, and an added feature is the bigger, flat base, that lets me set the tool down upright for quicker use.

The clips broke early on but I continued to use them just not in my Hackzall. One quit charging after a couple years and now the other quit charging.

These batteries pack a punch! I purchased these for my father for Milwaukee's M-12 driver and he couldn't be any more thrilled! My mom's complaining that my dad is up all night building stuff in the garage! Definitely a must buy!

both of my batteries stopped working.... and in both cases the solder connection on the positive wire came loose. remove the 4 torx screws from the bottom.... pull the top off.... and you'll see the wire immidiately! solder it back together... make sure its a really good connection, and you'll have a great battery for a really good price! it inconvenient and annoying..... but at least its a simple repair, when my milwaukee brand battery died...... it the circuit board, theres no fix for that.

So I’ve had these batteries for a few weeks now and they haven’t disappointed me yet. I decided on a whim to downgrade from Dewalt 20v equipment to the Milwaukee M12 line. I liked the smaller profiles which are more lightweight and easier to use all day long. But as far as the batteries are concerned they have worked flawlessly. Initially I used them right out of the box and drained them. As with any new batteries you want to drain them completely and then let them charge completely. This will help build a better battery life. These batteries have worked extremely well with all my M12 tools. They hold a charge as expected and fit perfectly with no issue. If you are on the fence about purchasing off brand batteries I certainly understand and I hope maybe my review can help you decide a little easier.
