Charging rates for tranny batteries

[gainsy]

Hi
I want to charge my 8 rechargable batteries through my Etronix Pulse tranny, they are 2500mah AA's, i am using a Imax B6 charger
My question is what rate should i be charging them at?
Not done this before so thought i better ask before blowing them up :D

I charge mine 2300mah at 1.0 amps.
