Hello,
By mistake I charged a new TX pack I built with new NiMh Sanyo 2500 with a Multiplex 5014 in NiCd mode. Before I noticed, they were charged up to 1600mah. The charge was at 200mah. I stopped the charge and switched the mode to NiMh and am currently charging at 200 mah/discharging at 500 mah (cycle) 4 times.
What damage if any may have occured to these brand new batteries????
Thankyou,
Joe

I don't think you could've harmed them at that charge rate. The difference between Nimh and Nicad charge types is peak sensitivity. When form charging a new pack, you WANT to go past the peak with C/10 rate to equalize the cells. Some folks trick their chargers into form charging a Nimh by setting it to Nicad so it won't peak.
Form charge is a slow (C/10) charge for ~16 hours. If your charger can't do 250mA then 200mA for ~19 hours should do the same thing.

Do to the low charge rate, no damage was done.
If any damage was done it was from stoping the charging process before it was completed. The need for a NiMH specific charger is only for peak charging not overnight charging.
