The Watson rechargeable lithium-ion camera battery provides a compact spare or replacement power solution for cameras that use the Sony NP-FW50 battery type.

It delivers 7.4V direct-current output with a 1100mAh capacity and 8.14Wh energy rating. Lithium-ion chemistry allows the battery to be charged or discharged at any time without developing a memory effect, making it convenient for regular photography, travel, events, and extended shooting sessions.

The battery works with compatible Sony cameras including Alpha a3000, a5000, a5100, a6000, a6500, a7, a7R, a7S, A560, A580, DSC-RX10, ILCE-QX1, NEX-3, NEX-3N, NEX-5, NEX-5N, NEX-5R, NEX-5T, NEX-6, NEX-7, NEX-C3, NEX-F3, SLT-A33, and SLT-A35 models.

Its compact physical dimensions make it easy to keep in a camera bag as a backup battery for photographers who need additional portable power while shooting away from a charger.
