Replacing old DeWalt Ni-Cd battery

[Avocet]

I have an old 12v DeWalt drill that still works fine but the battery is dead. Genuine new Ni-Cd seem hard to come by and there's the problem of the memory effect. I have one Ni-Mh battery which is fine but lacks the "kick" of the Ni-Cd ones. It lasts longer but I think it can't quite supply the peak current that the Ni-Cd ones can.

Would anyone recommend Li-ion? If so, can I use the existing charger?

Almost certainly not.

different chemistry you should never ever think about charging a third party battery with an old charger as a li-on can contain far greater energy and indeed catch fire if miss charged
after market nimh are great they dont have memmory effect can be charged at will and will have as much power as the ncads
