NP-F550

Arrived quickly and the batteries seem quality plus hold a charge nicely. I am using them on an external adapter for my original BMPCC camera and it's so nice to finally have decent battery power! First battery has held it's charge much longer than I expected and have used it over multiple days (of small shoots) before needing the second. Many competitors on here claim this model batteries are not for cameras, but only for portable lighting rigs.. this is false. Works perfect for my BMPCC.

Just amazing that this company could manufacture a product of quality that I would have thought Sony would have provided. The Sony battery that came with the Sony camera died, while a third-party battery is still functioning, and not only that the charger that came with this Wasabi Power Supply re-charged that one also. The batteries from the Wasabi supply slid in and out of the camera slot with no hang-ups, and sat there securely until it was time to release it. Just amazing that there are some companies out there who can provide quality products at a reasonable price.

The batteries work well and everything charged good. Don't know about longevity yet. We'll see. No instructions included though, so I had to search on the Internet to figure out how to charge the batteries with the lights.

Work well make sure you charge them first

Haven't had a chance to use my camera yet but I did insert it into the camera and it fit perfectly.

I have been looking for batteries for my device finally found these and they fit perfect! Great price 2 batteries with charger.

Worked well

These last long, charge quickly, are reliable, and fit a wide range of products, specifically various lights I use for video production. An essential tool at a very good price. For some occasions I may choose one of the larger capacity Sony compatible batteries, like if the light has to stay on for an extended time, but frequently I just need it for 1/2 hour or less and one of these does the trick. I have one light that can only accept this size, so I had to have them.

It's working great for dental loup univet .the battery life is much better than my original battery. (7 to 8 hrs) Thanks

The batteries are good and last long. My only complaint is that the batteries are somewhat of a loose fit, in the charger...so you have to plug the charger in upside down, to prevent them falling out. Takes about 2-3 hours for a full charge and lasts about 45 minutes in the Yongnuo YN-II 300 LED Light I use....that's on full brightness. I'd recommend buying these batts...they're good.

Good one

as I said, ok

The charger worked fine with my original Sony NP-F330. The Wasabi batteries however prompted an error message "info lithium only" and the camera would turn off. Size-wise close to the original, but the Wasabi's are a hair larger and sort of get stuck inside...
