    • Best batteries Milwaukee makes
These 5Ah packs run noticeably longer than the 2Ah and even the 3Ah batteries I was using before. Charge time is fast and they hold up well even after heavy use. Throwing in the M12 charger made this deal a no brainer and I use both chargers constantly in my shop.

What a great product, expensive. Milwaukee tools are pretty top notch. I've switched to all Milwaukee boxes and tools. I wish I could afford more of these batteries. Maybe they will have a sale this year🙏☺️ Thanks Milwaukee for such great products

    • Check your insertion and cycle the charger to get past the red/green blinking stage.
Was terribly disappointed because the batteries both flashed red/green which means the batteries are faulty and the charger will NOT charge them if indeed so. I was going to return them and complain a lot, but before I did that, I thought to seek solutions. After re-insertion of the battery and a re-plugging of the charger, it started charging properly. It's not easy to tell when the M18 battery is fully inserted. It could be better if the batteries locked in as my 60v batteries do their charger. There's NO MISTAKING when those are fully inserted. Look at the 1-star reviews--90% of them are "red/green" bad battery complaints. Try fixing things before complaining. Also note that the highly repeated technique on youtube of wiring one battery to another for half an hour was totally unnecessary. Also wouldn't have worked with two dead batteries and no other M18 in my possession. Four stars because the angst of a charger/battery setup that is prone to issues, especially this issue. ... show more
