The Sony NP-FV70 Rechargeable Camcorder Battery Pack (1960mAh, 6.8V) is a high capacity InfoLITHIUM V Series battery. InfoLITHIUM means that the NP-FV70 will display remaining battery life so you're never surprised by a loss of power in the middle of a shoot. The battery also features 15% higher capacity over the NP-FH50 and gives you the option to charge faster using Sony's optional AC-VQV10 fast charger.
