NEEWER7.4V/2600mAh Replacement Li-ion Battery for Flash, Lithium Battery Compatible with NEEWER TTL Z2-C Z2-S Z2-N, Z1-C Z1-S Z1-N, Z880-C Z880-S Z880-N, Z760-C Z760-S Z760-N Flash Speedlite, NB-Z1

These batteries last so long in the NEEWER Z2-S 2.4G TTL Round Head Flash Speedlite for Sony that I didn't even need two of them for the wedding I worked. Great flash, by the way. Super bright.

I shoot a LOT and I always drained my flash battery. Had to carry a backup flash, which was tedious. Just getting a backup battery is the answer. Easy, light, and simple. Love it. Should have bought this 2 years ago. HIGHLY RECOMMENDED

Neewer has outdone themselves again! This flash and flash battery are top notch. I can use one battery for an entire 5 hour wedding. The product itself is made with good quality material and so far as avoided scratches. The functions are very simple to follow and use to begin with the flash work immediately.

Always good to have a secondary battery for shooting on location events weddings gonna be getting at least two or three more of these batteries with probably two or three more of the lights as well

Like the flash and its controls. Works great at night also. Love the that it works as a slave or master. Works great with my existing remote flash controls.However there’s no diffuser that comes with it.You have to purchase this diffuser separately. Which I did.

Does what a battery should do.

Very pleased with my purchase

This is a great extra battery and it has long battery life.
