“Can I use a battery with different voltage in my Sony HDR-CX220E? I recently bought a Sony HDR-CX220E Camcorder. It comes with NP-FV30 which lasts for hardly an hour. I am looking for a replacement battery, NP-FV100. The original Sony NP-FV100 is 8.4V, but Digitek Sony is selling the same model with 7.2V.

Can I use this battery with lower voltage in my Camcorder? Will it give me the same performance? Thanks, Priyanka”
