Hi guys,

I need to safely discharge and charge my Tenergy 9.6V 2000mah NiMH 8-cell transmitter battery and my Futaba 9.6 V 700mah 8-cell NiCad.

I bought a IDST 608AC for recharging but, I don't know what selections to make on my ISDT 608AC's screens. The owners instructions pamphlet is useless. Any of you successfully using this charger? Can you guys look at the photos of the screens and advise what selections to make for each battery?
Maybe you can you explain what the words 'condition' and 'current' refer to?

First, I don't know a thing about this charger. So this is just an opinion. On the discharge setting the 0.90v is the voltage the charger discharges them to. The current setting is the rate of discharge. On the charge side, the condition is where the battery is charged and the voltage starts going back down. In this case when the voltage goes down 8mv the charge stops and the battery is full. The current is the charge rate. Again, I don't know this to be facts but I think that's what you have going on.

I'd charge the 2000mah one at 2 amps and the700 mah at .5 mp. That's conservative numbers. You can discharge them at about the same rates.

I think 1.1 volts per call is the lower discharge limit before you start damaging the battery. Personally I would take it down to 1.2 volts per cell to give 9.6 total discharged voltage.

He's cycling nimh and nicad, not lipo. Big difference.

True, NiMH is a lot more tolerant but you can still damage them if you discharge too far. NiMH really doesn't need to be cycled they way that the old NiCads do but if OP is checking capacity you still don't want to whack them too hard.

My old school nicad chargers / dischargers discharge NiCd packs at 500mah - 1.0 amp rate depending on capacity. There's no memory to cycle on any battery but on Nicad.
Mgnostic is right about not letting nimh reach zero repeatedly or for extended time. Keep NiMh at about 1v per cell for storage and repeat a charge cycle on them every few months.
​​​​​​The whole idea behind Nimh is that you don't have any reason to ever discharge those packs.

You should still cycle Nimh occasionally. They will still take a set even though they're not supposed to. I don't use Nimh any more except for transmitter and nitro power packs. We're kinda getting off the op's question here, though.

The manual truly is useless, but it's an automatic charger, aka smart charger. Pretty simple stuff.
Default discharge rate with that charger is 1.1v for nicad or nimh, which is fine. 0.7 amp discharge default setting on the screen is also good.
I can already see in the screenshot posted the settings are ready to go, I would hit the start button and eat some popcorn while I wait for the buzzer to go off.
The do's and don'ts are found on any other charger manual so you can refresh yourself on what you'd do manually.
You don't deep cycle NIMH batteries or cycle them. You can read any charger manual and become more enlightened what to expect. How about outdated to something current?
