Please help - NiMH discharge question.
I have an "EXPERT" 1500 NiMH 5 cell pack and so far I have only charged the pack (useing a Trition charger). Yesterday I have lost a plane due to battery failure. Although I has charged the pack to peak capacity, when under load the pack would not retain its voltage for more than 1 1/2 minutes.
I have a second plane with the same battery type and I don't want to make the same mistake. I would like to:
-charge the pack to peak (wright down the mAh it took)
-discharge+charge the pack (again wright the numbers)
In this way I want to check if the pack has any bad cell in it.
My question is:
-to what voltage should I set the Triton for discharge mode? (I don't want to over-discharge or under-discharge)
-what mAh rate should I set for discharge? (would like to match the "real" life factor when the servos are in use)
-how often do I have to cycle the pack? (at least for check up)
Since I'm useing the Triton I have to set the program in it before start the cycle.
Your help is much appreciated.
Thanks.

My question is:
-to what voltage should I set the Triton for discharge mode? (I don't want to over-discharge or under-discharge)
0.9v per cell. Most manufacturers recommend 1.0v
-what mAh rate should I set for discharge? (would like to match the !QUOT!real!QUOT! life factor when the servos are in use)
300 mAh (mAh / 5 = discharge rate)
-how often do I have to cycle the pack? (at least for check up)
I cycle my batteries once a month.
