Yeah thats ok for the first charge on a NiMH or NiCAD pack. But these batteries should be cahrged at 1C thereafter on a charger that has a charge problem able to deliver the correct current over time.
NiMH and NiCAD should npt be slow charged if you want to keep them in good condition. Slow charge is good for storage but not for regular use.
That is backwards
. Consistently slow charging at a C/10 ma's for 15 hours after using a NiCad or NiMh battery is the only way to assure long life. Charging at a 1C ma rate will cause the battery to deteriorate over a shorter time period. After a day of flying, I but both transmitter and receiver batteries on timed 15 hour charge at C/10. After 15 hours I switch to a trickle charge of C/50 ma's and leave the batteries on the tickle charge until the next time I go flying. My batteries last for many years. I have been doing it this way for 30+ years. Also I cycle the batteries at the beginning and end of the flying season to insure they have at least 80% of their rated capacity.
