I bought an 18 Volt Dewalt cordless that died on me.
I had too much money in the batteries and charger, so I bought another.

Then I got the Dewalt 20 Volt cordless.............much better.
I got the 20 Volt:
chainsaw
light
impact driver
leaf blower

Then I read on the internet that Milwaukee is better.

It took me all of the 1990s to wear out my Makita cordless drills with NiCad batteries.

I will die of old age before my 20V Dewalt drills wear out.
