USB-C charging law in the EU.

I think motor life on battery powered power tools isn't that important as batteries replacement cost is the real cost. By the time the motor goes bad it's about time to buy another tool. The price of the tool+battery isn't all that much different from the battery alone.

While usually you get a significantly better deal when buying a tool with battery bounded rather than separately, the cost difference is huge actually.

Usually the all in one kit includes the charger too.  And the batteries on my Bosch drill are still good after 5 years, I expect them to more than double that life.  A friend had a lawnmower with Li-Ion batteries, one of the first generations, and it did 10 years of summers (two batteries used per 'mow') before the batteries finally went bad.  I think modern Li-Ion batteries are likely to last even longer.  Once you get over that point you get to issues of obsolescence, will I be able to buy these batteries any more for instance...

Fully charged storage in hot conditions is what kills these power tool batteries. It's not as much capacity drop, it's the electrolyte reactions and thickening of the SEI layer which increases the equivalent DC resistance of the cells, so that they would still measure decent capacity under low discharge current, but sag in voltage in power tool use, so that low-voltage cutoff is reached way before 0% state-of-charge. It would be best to store the batteries between maybe 20%-60% SoC but then you need to remember to charge before use. I have made it a habit that I don't charge the batteries after use for this reason (but I don't attempt to optimally discharge them either, so maybe they are at 30%, maybe at 90% depending on what I was doing the last time). I remember some BOSCH batteries didn't last for more than 3-4 years or so when they sat in charger all the time.

*added*: I listen to a lot of 'stuff' whilst working, driving etc. for background noise, it might have been the latest Ham Radio Workbench podcast (hardly an authorative source on EU regs) with W1REX

This is EXACTLY how rumors and urban legends are spread and then amplified by algorithms and upset culture on social media and in coffee tables. If you do not know where you heard something and if you have not double checked the information to be accurate, do NOT regurgitate it forwards in ANY way. No matter if you mention or try to say that it's a rumor.

Someone WILL read/hear it "in passing", will forget/miss that it was supposed to be a rumor and will regurgitate it forwards as a fact.

Only way to stop bad information and misinformation is to not repeat anything unless you're absolutely sure about what you say is true.

This thread has devolved into meaningless chatter beside the topic. Are we talking about USB-C or are we talking about battery heating, is the battery in your milwaykee 18 or 20v and about construction workers using battery powered tools from PSU's?

Nobody's coming and stealing your Milwaukees nor putting an USB-C to an EV... just  calm down everyone and get back to the topic.

And remember, legislation in EU is not made by idiots. People reading the legislation badly and then reacting to it loudly are idiots. They just jump to a conclusion and then rage about it and balloon the issue with imagined scenarios and horrors. And also, people writing news and articles MIGHT have anti-EU or anti-regulation stance, thus they will lie to you and get you reacting and retweeting before you even know that they just lied to you.

Our bananas are still not straight, our cucumbers neither. Kids can still play on playgrounds, mozzarella is still not made with powedered cheese, British kept their wonderful power plugs and we do not have to worry about USB-C in stupid and nonsensical use cases being forced onto people.

Calm down and keep discussing about the topic at hand :D
