Zoe ★★★★★ Oct 22, 2026

Battery life on this one easily matches the Sony original I had before, and it holds a charge for weeks between shoots. The build feels solid, and my camera reads it as a genuine battery with no error warnings.

Timothy C. ★★★★★ Oct 21, 2026

I’ve been using this NP-FW50 in my Sony camera for a few weeks and it holds a charge noticeably longer than the factory original. The battery meter stays accurate all the way down, so I never get caught off guard.

Ava ★★★★★ Oct 20, 2026

Went through a whole day of shooting and the camera never blinked, which is more than I can say for the original. These hold their charge really well and seem built to match the OEM spec exactly.
