Replacement NP-FW50 Battery

The Kastar NP-FW50 is a lithium-ion replacement battery rated at 7.2 V and 1650 mAh. It fits Sony mirrorless and SLT cameras including Alpha 6000, 6100, 6300, 6400 and 6500 series as well as NEX and Cyber-shot RX10 models. It also works with Sony BC-VW1 and BC-TRW chargers and VG-C1EM or VG-C2EM grips. The single-pack unit is supplied new and ready to use.

Lithium-Ion Chemistry Limits

Lithium-ion cells deliver 11.8 Wh from a compact 3 by 2 by 1 inch form factor. The chemistry self-discharges slowly but loses capacity if stored fully charged or fully depleted for long periods. Built-in circuitry guards against over-charge, over-discharge, over-voltage, over-current and over-heating to meet UL 1642 and CE safety requirements. Extreme cold or sustained high current draw will reduce available runtime.

Capacity and Practical Headroom

The 1650 mAh rating supports extended shooting sessions on compatible Alpha and NEX bodies. Video recording, continuous autofocus and frequent image review consume charge faster than single still captures. A spare unit is advisable for full-day events or travel where charging opportunities are limited. The protection circuit stops output before the cell reaches a damaging low-voltage state.
