Four-Pack Li-Ion Camera Batteries

This pack contains four Kastar NP-FW50 lithium-ion batteries, each rated at 7.2 volts and 1650 milliampere-hours. They are direct replacements for the Sony NP-FW50 and W Series batteries used across a wide range of Cyber-shot, Alpha, NEX and SLT cameras. The set suits photographers who need multiple spares for long shooting days or travel.

11.8 Wh Capacity per Battery

Each cell stores 11.8 watt-hours of energy, giving noticeably longer run time than lower-capacity alternatives. The pack comfortably powers a camera through extended stills sessions or video recording, but continuous high-drain use such as 4K video will eventually deplete a single battery. Four units provide enough combined headroom to swap cells without interrupting a full day of work.

Built-In Protection Circuits

Every battery includes over-charge, over-discharge, over-voltage, over-current and over-heating safeguards that meet UL 1642 and CE safety standards. The protection circuits keep the cells stable during normal charging and shooting, so the pack runs cool and quiet without external cooling. No fan or active thermal management is required, and the batteries draw only the current the camera requests.

Questions about this item

Will these 1650mAh 7.2V Li-Ion batteries work in my older Sony NEX-5 and Alpha 7 cameras?

Yes, the pack is compatible with Sony NEX-5, NEX-6, NEX-7 and Alpha 7 series bodies that accept the NP-FW50 form factor.

How can I confirm each 11.8 Wh cell is charging and holding capacity correctly?

Insert a battery into the camera or a Sony BC-VW1 charger; the on-screen or LED indicator will show charge progress and full status when the cycle completes.

What comes in the 4-pack and do I need a separate charger?

The box contains four Kastar NP-FW50 1650mAh batteries; a compatible charger such as the Sony BC-VW1 or BC-TRW is sold separately.
