Cycling Nimh batteries

I have a 2000 mah transmitter pack (JR 12x). I would like to cycle this battery to refresh it. After only a few months, I am only getting a days worth of flight time out of it...and for me..thats not a lot of flights...maybe 5 x 12 minute flights. I have a Bantam BC8DX that will cycle the battery...what settings should I use. What should the discharge and charge settings be set to on the cycle.

Re: Cycling Nimh batteries

Somethings not right with that pack. I have 1650 mah in both my tx and there good for about 5 to 6 hours on a charge. I try not to charge them until they are down to 9.6 volts. When I cycle them on my BC6 I discharge at 250mah and charge at 150 mah. I know that sounds low but nimhs don't like fast charge. I normally charge them at 120mah. And thats about every 2 weeks. Cut off voltage should be 1 volt per cell. Hope this helps.........

Re: Cycling Nimh batteries

I've got dark green Sanyo 1650's in my 10X and I'm getting about 9 1/2 to 10 hours out of them before they get to 9.6 volts. (I get tired before they do!) I put them on an ACE DIGIPACE III only to discharge them and I charge them with one of the new 9.6 volt JR wall chargers made for NiMh batteries. They charge any of the 1600-2700 NiMh transmitter packs only according to JR. If I use the ACE Digital Varicharger to charge with, I set it at 200 mils for over night. The JR wall charger only wants ten hours max according to the package it came in.
