Questions & Answers
Stupid question but does this battery actually work in the 1/2 m18 fuel impact?
Asked by Roadsideking August 2, 2018Yes, it's the best of the best. It was made for the bigger tools but works on all m18 tools. It's the only battery I can use on my Milwaukee chain saw!
What is the mAh capacity of this battery?
Asked by Tommy October 5, 2018As it says on the battery, its a 12Ah battery which equals to 12000 in mAh. "To convert Ah to mAh, you need to multiply the number of Ah by 1000" Also,, The bigger question should be what is its watt-hours(Wh)?.. if you trying to find out its total run time on a single charge...

Asked by AxeMan July 16, 2018I have never heard of a 18620 battery. I have heard of 18650s tho. My home solar set up uses over 1000 of them. It has reduced the bill from $400 to $90 a month. Also 26650 and 32650s as well as 17650s which can take the place of 2 cr123s.
