Hi, Got an old Sony Hi8 TR713E which uses InfoLithium "L" series and an AC-V700 charger. I'm hoping to upgrade to a digital CC in order to use "L" series with a Sony CC. Anyone know if my "L" series would be compatibile with any of the other series? "M" seems the nearest size etc, but I just don't know. If the "M" series can fit into my charger that would be something too. If no to all, then it will probably stop me looking at just Sony for a CC replacement! G.
