Questions about this item

How long will the 1650mAh capacity actually run my camera?

The 1650mAh rating at 7.2V gives 11.8Wh per cell, so run-time depends on the specific camera model and shooting style rather than a single fixed figure.

Does the NP-FW50 form factor fit the Sony BC-VW1 charger?

Yes, the pack is listed as compatible with Sony BC-VW1 and BC-TRW chargers, so it will charge in those units.

Will these batteries slot into a Sony VG-C2EM grip?

The compatibility list includes the Sony VG-C2EM grip, so the NP-FW50 cells fit that accessory.
