rcbjr, any update on this? i too am wondering if i can use my 7100t charger on my 8700c. and i did also notice the 7100 charger has an output of .5 amps whereas the 8700 charger has an output of .75 amps.

i know i should just try it, but i don't want to risk any damage to the 8700. i'm no electronics expert so i'm not risking it...........
