Promaster NP-BX1 鋰離子電池 適用於 Sony

These work perfectly in my Sony a6000 and last just as long through a full day of shooting as the original ones I had. For half the price, they’re a no-brainer to keep as spares in the bag.

Having used these side by side with the original Sony ones, I honestly can't tell the difference in performance—they hold a charge just as long and fit perfectly in my camera.

Swapped out my old Sony battery for this one and it holds a charge noticeably better, even after sitting in my bag for two weeks. It’s been a solid, reliable backup for long shooting days.
