Hello, I have got an old skool Riko charger and have got a 3700mah battery pack.
Now thing is I don't know the ma of the charger to use the calculator below:

The charger is the 30 minute dial type.

Thanks.

EDIT: it's ok I think it's- 2amp = 111mins for 3700mah.

Without doing the math 111min sounds right. But the best way is to monitor the pack closely during the first charge and stop it at 125F degrees. Once you know how long it takes you can set your charger to that amount of time and you will be good.
