I avoid battery-powered tools. They are wimpy, and the batteries will die in a
year or two.

You have a cellphone?

Sure, a simple one. I charge it about every other week, and I've
replaced the battery once. But it's not a power tool.

You're not going to get a horsepower or so out of a battery for long,
especially when the battery is two years old.

Yes, true, at 100% charge /discharge about 350 times or so on a lipo.
I have VARTA datasheet somewhere .. for the LP523450LP I am using (3.7 V 1Ah single cell):
300 cycles at 80% capacity
500 cycles at 70% capacity

2 years...

Cellphones do not always discharge 100%, had my Nokia for at least 3 years, charged every day.
Ther are bad batteries too, some die after a week.
