TL15 fuzzy logic charger

[The Laughing Man]

hey guys,

so this is my first try with this thing, so i wanna make sure i get it right. i have a game tomorrow and its 2am here now...

i have a tcp ni-mh & ni-cd tl15 fuzzy logic battery charger. the type with the screen and the dial for altering voltage. it has a discharge function, a fast charge - where i can alter the voltage input, and a slow charge, which puts in 0.2 volts but actually doesn't seem to do anything.

i have a crane stock 8.4v 2200mh battery. i've put the charger on fast charge at 0.4v of current. but when i switch to the voltage screen after a minute or so, it's already gone up past 9.2..

how long should this take? am i doing it wrong? can i even get it wrong with these digi ones or do they automatically stop when they need to? it seems to have got to 9.4 after about 10 minutes and is staying there..

i'm completely electricity illiterate - any help would be great..
