It should top out at around 2300 Mah +/- about 5%. Every battery is a bit different on it's capacity.

What I do with my Ni-mhs is cycle them 3 times when they are new. This will help form the battery, but on the discharge cycles you will get the capacity of the battery. Record this. Then about once a month I cycle the battery and compare the results with the initial capacity. When it gets down to about 80% of the initial value I take the battery out of service can replace it.

I use 1/C  Discharge: 1C Charge. So for a 2000mAh pack I charge it at 2A.

For new batteries the initial charge is always a slow charge on the slow charger supplied, even if that takes 2days of charging, thats what I do.

Thereafter and I discharge and charge at 1/C : 1C Charge
