CH-910 vs CH-900
 

what is the difference between the two?

after owning two xl1 for three years i finally want to pick these up...is the new CH-910 xl1 friendly?

i have the ma100 adapter, also what is a fair price, is a $170 good?

also while on the subject of batteries, i have an equal amount of canon and knock offs (the silver kind), i notice the silver kind tend to drop power very fast (power indicator almost instantly goes to mid power), however over all they both have an equal life span...does anyone else get this...?

so many questions

as always thank you for taking the time to read my post, and any help is much appreciated

The CH-910 is a dual-battery charger and holder. It's principally designed to clip onto the back of an MA-100 or MA-200, although it can also clip onto your belt. Slap two BP-945 class batteries into it and you're good to go all day and maybe into the evening. It is, indeed, compatible with the XL1 and even with the GL1 and GL2.

I'm sorry but I don't understand your battery question.

I have been wondering too what the difference between the 900 and 910 model dual battery holder charger is. Can someone explain this?
