Cam batteries... Sony NP750 and NP720 = same?
 

Is the Sony NP720 just an older battery, but the same as the 750?

I can't find it on Sonys web site but I have a few of them from my old VX1000... and I want to use them with my VX2100. Just trying to find out if it's ok before I shove them in there or charge the 750s on the 720 charger.

Anyone know?
