Kastar NP-FW50 battery and LTD2 USB charger

This set provides a 7.2V 1650mAh lithium-ion replacement for the Sony NP-FW50 and W-series cells. It fits Sony Alpha a7, a7 II, a7R, a7R II, a7S, a7S II, a6000, a6100, a6300, a6400, a6500, a3000, a5000, a5100, NEX-3, NEX-5, NEX-6, NEX-7, RX10, RX10 II, RX10 III, RX10 IV and SLT-A33, A35, A37, A55 models plus VG-C1EM and VG-C2EM grips.

Capacity and charging headroom

The 11.8 Wh cell delivers standard mirrorless runtime for stills and short video clips. The dual-slot LTD2 charger powers one battery at 8.4V 800mA or two simultaneously at the same current per slot, so a full cycle takes roughly two hours per unit. Continuous 4K recording or extended burst shooting will drain the pack faster than the charger can replenish it.

USB power delivery limits

Input accepts 5V at 2-3A through Micro-USB or USB-C, capping total draw at 15W. The 800mA per channel output is fixed, so higher-amperage power banks will not speed up charging. No AC adapter is included; a separate 5V 2A or 3A source is required for operation.

Questions about this item

Will the NP-FW50 1650mAh battery work in my Sony Alpha 6000 alongside the original Sony battery?

Yes, the Kastar NP-FW50 is listed as compatible with the Sony ILCE-6000 Alpha 6000 and replaces the Sony NP-FW50, so it works alongside original batteries in that camera.

How does the LTD2 charger show that the 7.2V battery is charging correctly?

The intelligent LCD USB dual charger displays charging status and battery capacity, with an output of 8.4V 800mA per slot to confirm proper operation.

Does the box include a Type-C cable for the charger's 5V 2-3A input?

The package comes with a Micro USB cable; the charger has both Micro-USB and Type-C inputs, so a Type-C cable must be purchased separately if preferred.
