A bit late to the conversation. I'm a big fan of the 18V NiCad DeWalts.
As an FYI I stumbled across several YouTube videos on "reviving" dead NiCads. Having several 14.4V and 18V batteries that would not take a charge I gave it a try and so far I'm 2 for 4 on getting batteries to take a good charge. Maybe I was lucky and Darwin didn't get me as this could be one of those "hey y'all watch this!" sort of techniques.
IF YOU TRY THIS IT IS AT YOUR OWN RISK!
The most "scientific" account said that you needed at least double the voltage to zap the dendritic sulfate crystals that sort out the battery. I used my 36V golf cart for the source. Some folks used a welder which seemed really scary.
