“How long to charge the new NP- FV 30 battery for the very first time? Hi, I just bought a new Sony HDR-CX220 camcorder and charging the new battery for the very first time. The battery pack is infoLithium NP-FV30 How long should I charge the new battery for? Should new batteries be charged fully 8-12 hrs for the first time? Also, I'm using the camera's USB cable to charge via a wall USB charger similar to those used for charging iPads. Will that work to charge the Sony battery too? Thanks!”
