I bought an 18 volt - 3/4 impact wrench kit and a bare tool grease gun. Do you leave the batteries connected to the tools? Or disconnect them after use? thanks
Mostly connected, ready to grab on the trucks.
Some in the tool, some in the charger. the rest are on the shelf ready to go.
I store my batteries at 87% drained in the tool. Just enough battery that the tool comes on. That way I can be well into a project, with two bolts to go for the impact, or three grease zerks left, when the battery dies. I get great exercise walking back to the shop to get another battery, from another tool, that's also mostly dead. I can then put them both on the charger, while I finish with a ratchet. Its my health plan.
I leave mine attached and it's seems fine though mine stuff is pretty new. I've left a battery in the charger as well, otherwise I'm also on @crane operator 's health plan.
Good choice with the Milwaukee M18s. For years and years I've left batteries in my cordless tools - works for me.
Is 87% drained mean one red light on the battery when you press that little button? If so that's how I do it too. Never thought of it as a health plan, I need to rethink this method. Usually I'm apologizing to the Lord for all the foul language that inevitably comes with the dead 18V tool that I really needed to finish the job.
I store mine in the bottom drawer of my toolbox. 95 degrees above to -25 below. When they’re dead I charge them. Otherwise I drive them like a rented mule.
In the bed of my pickup where rain puts them under a couple of inches of water........... Really. Killed a battery and now the hammerdill sounds funny. It's been a bad month for tools around here. I try to keep one battery on charge and the other in the little impact. Now that I'm down to one battery I don't have a system figured out.
I have batteries in each tool and a couple of spares charged on the shelf. I try to check the battery in the tool I am about to use before I leave the shop area and if it is low, I grab a charged one. Haven’t had any issues yet. Cam
if storing them over say a winter or long periods of time, the suggested way to store them is in a place with a stray temp and batteries at about half charge, this is said to keep the cells lasting the longest they can I typically move mine in from the unheated shop to a heated building for winter time large temp swings even from hot to cool can damage cells(not a LOT bu it does happen)
