I've had great luck with the Milwaukee M18; I almost never bring in my
tool batteries anymore, unless its going to be below 0. Love the
cordless shop vac.
I also use Ryobi, for my less used tools (ie.circular saw) and they have
excellent performance for the money. Not quite as temperature forgiving
though.
As for Milwaukee chucks jamming up; I only had that happen once after a
bunch of hammer drilling in Haiti. Scrounged all over the village for
the special star keys to take apart the chuck, but it just needed to be
cleaned.

Really Happy with the Milwaukee M18 volt series. Various sized batteries available, &
there have to be 150+ tools in the M18 series. I got into the Milwaukee 28 volt originally
& what a nightmare; too heavy, replacement batteries were $$$ & life span on the
battery was not good.
I have been told the Milwaukee power tools have steel gears not plastic. The
impacts are bomber solid.
So far cold weather operation is good, no noticeable deficiencies. & I have charged them
very cold so the battery charger BM is fairly smart/sensitive. I have noticed if really cold
the charger says "broken Battery"
I Loved the small cooler & reptile heater idea! Great idea!

Subject: Re: [RE-wrenches] Lithium Ion tool batteries
What lithium battery powered tool brand that has the best performance in
freezing weather? My 10 year old+ Makita tool set isn't nearly as powerful as
some newer tools. Even with new batteries, the tools have sufficient power in
cold weather.
What is the best brand for cold weather operation?
Thanks,
Drake

Generally, storage or use at cold temperatures shouldn't be an issue,
as long as the battery can still deliver enough power to operate the
tool effectively.
Charging though...at cold temperatures, ion mobility goes down. If
the battery is charged too fast, the lithium ions can't make it into
the graphite anode fast enough and they start to plate out as metallic
lithium. At best, this results in a permanent reduction in capacity.
Next worst from there, the lithium metal can create an internal soft
short, immediately or at a later point in time, resulting in high
self-discharge or a dead cell. Worst case, it turns into a hard short
and a fire.
In theory, the BMS or charger should prevent charging too fast or too
cold, but who knows if an edge-case like this is actually implemented
correctly on any particular battery system. Be careful charging!
