Having owned many of these, i often wondered on how to get
the most lifetime out of the battery's.

I have had little used 14.4 volt drills that after 2 or 3
years the battery packs become very degraded. I this case,
the drill sits unused for a long period of time, then recharged
before next use.

Laptops, same story. occasional use, sits for awhile then used again.

Batteries are usually rated for so many cycles of recharging.
So, should it be better to constantly recharge the units,
or only charge as needed?

The charge as needed method for units that sit for awhile does not
seem to work out very well. I have a number of drill power packs
that i need to find some of those tab ni-cads for. I think there
c size or such. Anybody with tips on that let me know..

Keeping them constantly plugged in seems to me would use up
there number of charge cycles and shorten life to.

so, whats the best way to get the most out of rechargeable battery
packs?

And how can hybrid cars get 10 years out of a battery pack
when i am lucky to get 2 or 3 out of most of the packs i have?
I do see online how some of the early gen Prius packs are failing
much to the owners displeasure.
