Which are best. Looking to buy a replacement drill as the damn thing doesn't
hold charge long and is always flat. My local too shops has drills with Ni
Cads and lithium batteries. The thing that I know aboy NiCads is they are
expensive and sooner rather than later totally give up.

Same applies to NiCds particulary when cells are made up into

Can't say I was over enamoured with the only Li ion power tool I've
ever owned. An Aldi/Lidl screwdriver, put any half decent load onto
it (like a semi tight screw) and the battery protection cut in. May
have been a faulty unit, only used it a half a dozen times. Put it
way came to use it again and it was flat and refused to take a
charge, got a refund.
Just recelled the ancient B&D screwdriver that is excellent and much
better than anything "modern". Put NiMH's in it and am very careful
about charging it as it is a "cook your cells" type charger...
You want to take it until the performance starts to drop off - but stop
before there is a chance that any individual cell is completely flat. If
you have been working it hard, and the batt is warm, then also leave it
to cool a bit before recharging (assuming its a fast charger).
Li-ion will have circuitry that will disable the device once the cell
falls below a certain threshold.
Its not just the type of battery, its the quality of the battery and the
type of charger. Quality brand chargers don't cook the batteries.
NiCd are the cheapest, then NiMh then Li Ion.
For DIY use, there are some great offers on Makita with NiCd batteries &
very smart chargers.

Had a Bosch NiCd and the batteries died in no time, after light use.
Now have a Site NiCd but not had it long enough to judge the lifetime
of the batteries.
I'm sure NiCds will not be available at all for much longer.

Probably beyond the life expectancy of any cells you buy now anyway, so
not really worth considering.
Also not worth worrying about as long as the tool and its charger has
the option to use NiMh (as most decent ones do). When it comes time to
replace the batts, you just buy whatever is available at the time.
I invested, six years ago, in a Metabo Li-ion 14Volt drill. I have
misused it almost every day since then, and it has never let me down.
OK, the cells need recharging a bit more often now, but they still hold
the charge well. The included 15-minute fan-cooled fast-charger is
I think the issue is not which kind of cell, but what quality of cell,
and what quality of charger.
