This might be slightly OT, but does anyone know what Samsung does to
determine whether it's one of their own OEM batteries that's being
used in their VPHMX10 camcorder - rather than a chinses-sourced
lookalike?  When the non-OEM battery is installed, the camcorder
brings-up the message. "Check the authenticity of this battery".  The
battery is a three-terminal device - for a simgle 7.4V rail, so I
guess there may be something very simple going on re the third
terminal, but I don't know how the 'intelligence' is gained :-/

HYCH,

Cheers,

Pete.
