Frequently asked questions

The Milwaukee M18 RED LITHIUM XC 5.0 Ah Batteries are designed to provide up to 2.5X more run-time, 20% more power and 2X more recharges than standard lithium-ion batteries. However, the actual battery life depends on the specific tool you're using and the type of task you're doing.

Yes, the Milwaukee 48-59-1812 M12 and M18 Multi Voltage Charger can accommodate both M12 and M18 batteries, eliminating the need for additional chargers or adaptors.

  • Good
Great batteries, hold charge very well, nice weight with good power. I was worried it might be a knock off battery but it wasn’t worked great.

  • True Milwaukee
Best value you'll find. Far better than the stores they are true Milwaukees they charge like normal and produce long lasting power. Easy to use and fit all of my Milwaukee tools. The charger doesn't make any noise that I can hear.

  • New batteries and charger for a very decent price
My friend gave me a Milwaukee tool set, which stopped working for some reason. The 1.5 Ah battery was dead, the charger did not have any lights and would not charge the only battery I had. I opened the battery and carefully charged the cells bypassing the safeties. Still it would not run the tools or charge in the charger. Since I did not know what was wrong with the set I decided to buy this kit, which includes both batteries and a charger. It turns out I made a good decision. As soon as I put the old battery on the new charger it started charging. Right away I took it off the charger and put it on a tool and it worked as well. So the old charger was bad and the original battery needed a good charger for a couple of seconds to reset the safeties. Interesting... Now I have a set of a compact drill, impact wrench, 3 batteries and a charger. Let's talk about the batteries and the charger. They came in the sealed Milwaukee Starter Kit box. Everything looks authentic, but it came from China and all bets are off with this country. I have seen too many counterfeits in my life. For this price it has to be a counterfeit product or a quality reject from the original Chinese factory. We'll never know for sure. But the product looks and feels like the original Milwaukee. I even weighted the batteries and got 716 and 725 grams. One Youtube video says a 5 Ah counterfeited battery weighted 649 g. By the way both batteries came with little charge and 1 light on the fuel gauge, I measured 17.80 and 17.78 V across (+) and (-) terminals. After full charge one new battery measured 20.73 V. The charge took a little over an hour, but the battery still had some initial charge in it. At the end of charge the charger was quite warm. Time will tell if it is a good purchase. I will post un update after awhile. For now this product deserves solid 5 stars, counterfeit or not. ... show more

  • Great! They Last A Long Time, But Are Kind Of A Pain To Charge.
Ordered these brand new, and they work great. First time charging is a pain though. You need to press really hard on the charger to seat the batteries (I thought the charger was going to break).
