The works SDS drill still uses NiCd cells and ruins them quickly. We were talking about a NiMHi conversion but told the charge rates are different. What is the charge rate difference between a NiCd "C" cell and a NiMHi "C" cell?
isn't there also a difference in charging methods? from what I can tell from my charger (RC competition charger) you have the "linear" and "flex" mode... don't ask me what they stand for, I only know that there is a difference in charging nicd and nimh cells. Also, the charge rate depends on what type of cells you use (HV, regular,...)
It's not a difference in charge rate, but there is a difference in charge termination, the way NICD chargers know when a NICD cell is charged is different than that of NIMH cell, NICD chargers overcharge NIMH cells because they don't detect a full charge, you will need a charger compatible with the number of cells (pack voltage divided by 1.2) and that is made to charge NIMH cells, the charge rate (amps) is of little importance.
Yes but sometimes the memory effet get to hopelessly unuseable levels. I'v got 16 Xaa's that suffer from the memory effect (product of my youth)
There's a trick that worked for me on an old Nicad phone battery that wouldn't take a charge - charge for a second on 12V.
