but is there an ideal 'trickle' charge rate for Ni-mh cells ? i dont need to fast charge these items - they are used in my model sub and get used about once or twice a month, they run the model for around 4 to 5 hours per charge - everything seems fine to me ! i currently use a 'multi lader' charger- with at output charge rate of 500ma- its not a peak detect type charger..... so currently i am charging a 12 volt ( 10 x D cell ) 9000mah pack at 500ma for 22 hrs..... everything seems fine but fellow club members seem to think the charge time is way too long.....??? i am not bothered about charging the cells quicker....But i want them to be 100% fully charged or as near as possible... so am i fully charging them ? is the charge rate sufficient ?- should i 'warm' the cells up abit more by increasing the charge current !? any thoughts ?
