I have purchased a used nitro R/C. It has a 5 cell pack. Each battery in the pack says 1.2 V 1000mah ni-mh. I cannot make out the manufacturer.

With a multi-meter, how do I know if the pack is good?

Voltage is at 6.2

Electronics worked when purchased after a quick 5 minute charge on a "quick charger"

Thanks

5 cell packs whether they're flat or hump packs have a minimum voltage of 6.0 volts. So 6.2 volts means the pack is ok.

What should the voltage be fully charged?

How long should the recharged battery last while powering throttle and high torque steering servo. Tough question I know, but I have no idea.

Just get a new pack if your that unsure about it. Make sure you have a failsafe if you do decide to use it. 1000mah really isn't much and won't last long anyways, maybe 10-15 mins on a used pack depending on the amount of power your servos draw.

Me again...
Cell pack is reading 6.6V, but servos only work for about 1minute. Afterward, pack still at same voltage. Swap in my 4 x 1.2 rechargable AA's and all is good for a long period of time.

Is pack dead? Is there a way to test?

That's how every nimh battery I've ever had ended it's life. Voltage okay but no oomph even of you get it to take the rated mah.
