It is my understanding that the first charge on a new 4 cell Nicad battery pack shoud be at a C10 rate for 16 hours. I have a new 2400 mAH 4 cell pack and the slow charger I have has a max charge rate of 120mAH for 16 hours.
120mAH charge rate for my 2400 mAH 4 cell pack would be a rate of C05, so is it safe tp assume to get a full charge on this pack I would charge it for 32 hours at the 120mAH rate?
Would this be equal to charging the pack at 240mAH which is C10 rate for 16 hours ?

That won't work properly and will shorten the life of the battery plus you will never get a full charge.

Many seem to incorrectly think you just divide the charge rate into the battery mah rating and use the answer as the correct number of hours to charge it. That is wrong and would lead to people using 75mah wall worts charging huge batteries for days at a time to get the proper charge.

To do it properly you should charge that 2400 pack at 240 mah for 24 hours for the first charge and then 16 hours at 240 mah for subsequent charges.

Thanks for the reply, but I don't have a charger available to me that will charge at the 240mAH rate. So short of that I am looking for the best alternative.

I would think a Triton (or similar) at 200mAh would be okay??

Also, something to watch out for with Sanyo 2400's, they develop a "memory" after a relatively short number of charge/discharge cycles.

Cycle the pack once every 20-30 charge/discharges, 500mAh load to 4.4v pack voltage. Charge as normal.
