Actually, I have two batteries for my D70, so despite taking over 500 pictures (and reviewing and deleting lots more) I never had to charge the batteries, and still had lots of juice left at the end.
Having said that, I woudln't have been a problem anyway. India's power is 220v, but the D70's (like most) charger is rated from 100-230v, so you don't need a voltage adapter (which is pricey).
My friend picked up a powerbar/socket converter combo, (plugs into India type socket, but bar is North American type) for about $10CND in Delhi... but I never had to use it.
Also, I'm not sure what you mean by 'post bond' on my gear. The only thing that was recommended to me was to register the camera at Canadian customs to have it recorded as being bought in Canada... to avoid the incoming guys thinking I bought it in India. I didn't bother with it, and they didn't even ask on the way back in.
