You can hold down the button on the battery till it starts to flash and there is a code that tell you how many cycle that battery has gone through. The code i looked it up but that was a long time ago and cant remember where.
Thats what I use for mine, works great.
Yes. working very fine. 35 minutes with full battery in 0880-20 vac.
I don't know if it has that feature built in but I will say the batteries charge extremely fast with this charger. We are very pleased with the purchase.
its run time in hours the ah stands for amp/hours, so 3.0ah three hours 4.0 four hours 5.0 five hours you will pay alot more for higher run time. me i have 6 3.0ah batteries with the 6 battery charger and just cycle through them.
This will fit any Milwaukee M18 tool
It can be used for any M18 tool
Detach them if left over 24 hours and don't forget them on the charger. You will kill their strength.
Depends on use mine last a week so probably 8-10 hrs of steady use
