Newell Battery NP-FZ100 for Sony

Bought this as a spare for a long wedding shoot and the battery held up through nearly 900 shots without a hiccup, which is way better than I expected from a third-party option. It charges quickly in the wall unit and the capacity indicator on my camera stayed accurate the whole time.

Third-party NP-FZ100 is a solid backup for my Sony shoots; it held a full charge after sitting in my bag for two weeks, and it didn't trigger any error codes during a two-hour event.

I’ve been using this battery for a week now and it easily lasted through a full day of shooting with my camera, including video. The charge holds steady even in cold weather, which was a pleasant surprise.
