Nimh Peak Charging

[jkelm24]

When setting the amp rate on my peak charger for nimh packs, I've always used the mah/1000 rule to set the amp rate on the charger. Example: 3000mah/1000 = 3amp.

I've recently read that it's safe to charge at twice the base rate, meaning 2(3000mah/1000) = 6amp. (although the reference was discussing old nicd cells, not nimh)

Is it safe to charge nimh cells using the 2(mah/1000) amperage? If so, will I then have to also adjust the peak voltage sensitivity as well?

NICD would be like 8 milli Volt (.08) and NIMH would be 5 milli volt (.05) so as soon as the tigher peak detect hits it pops the cell off faster down to no charge or trickle.
for NICD sometimes peak would be set at 12 millivolt (.12) because you want that cell roasting off charge depending on what you were trying to do to the cells.

I'm assuming you're meaning volts in your above bracketed values... in which case, 8mV (millivolt) would be 0.008V (eight thousandths of a volt), not 0.08V... same for 5mV (0.005V) and 12mV (0.012V).

In the interests of clarity...

Thanks for the clarification guys! Much appreciated.
