Powerful charger
The Milwaukee M18/M12 charger is small but mighty. Packs a pinch. Great for all my battery Milwaukee tools!

Dependable and Enduring
After the first charge subsequent charges seem a bit quicker even when the battery is completely empty. This is a big battery pack runs for a long time. It's hard to give a definitive time because different tools use different power.

You just can't beat the milwaukee m18 batteries and tools
I have been using these a while and these 5.0 batteries will get a lot of work done on a charge. I use them in a variety of tools from drills to saws to leaf blower to weed eater etc and they are work horses. I love that every one has a charge indicator - not just the higher AH batteries like some vendors.
I hav e several chargers on a charging station and a variety of batteries on tap so even if I'm working the whole long day with them I'm never at a loss for power. These 5.0's are a good size for a drill or impact driver although sometimes I like the smaller ones for light jobs. But where I'm going to be doing more these is the ones I reach for. My drill is probably the most heavily used of all my milwaukee tools so I use this size battery a lot.

Is This Normal??
Charged 6 amp battery well. But when placed 8 amp hour, only one light stays on and the batery or charger starts to make a “Sizzling” sound. Tried several times. Same thing

I tried the 8.0 in my blower that I usually only use a 9 or 12. I couldn't believe how long it lasted, but note it didn't have as much power as the 12. When I was done I still had 2 bars?

Milwaukee Tools has once again come up with a very handy tool. Milwaukee tools and batteries are phenomenal. It is a great battery for all of my Milwaukee power tools. It has a good run and recharge time. I have two of these unit so I could simultaneously charge two batteries. It is a great battery and should last for a long time if not FOREVER. Highly Recommend.
