Rechargeable Battery Rebuild Questions

I have several Dewalt 14.4 's
Anyone got experience rebuilding these?
Where and what batteries do I need
whats a great price per battery - got a good source? ($5 ea is a deal killer - $40 gets a new rebuilt, this has 13 batteries)
AND can/do Nimh's work well with the Dewalt charger or should I stick to Nicads

It depends on the charger. If it was designed to do both then it obviously will. But I wouldn't gamble unless Dewalt said ok. The reason is that fast chargers monitor both the temperature and an end-of-charge signature of the battery. The temp profile of the NiMH may be different than the NiCad. The end-of-charge signature *is* different. Many fast chargers use the negative delta-V method and NiMH cells have a smaller delta-V than NiCads. This smaller voltage may not be recognized by your charger and it could then overcharge and damage the NiMH cells. There is another complicating factor. Some chargers monitor the total charge delivered to a battery pack and terminate at some fixed quantity. If your charger does this then it may not fully charge higher capacity cells than the original ones(ie 2.2AH vs. 2.0AH). This will not harm anything but you would not be getting the extra capacity you paid more for.

I cannot get onto Primecell's website but the Voltman site is good to go. I need to have my Dewalt 14.4's done and at this point, Voltman is the way to go.
Let us know what you find.

FYI, the PrimeCell website is working again.
