Important Notes
- This is a YO camera battery brand compatible replacement. Specifications, dimensions and connectors match the original battery and it fully replaces the OEM pack (not an original-brand product).
- TNP-FW50 is a third-party model designation; the corresponding OEM battery is NP-FW50. Please check the label inside your camera's battery compartment before ordering.
- For long-term storage keep 40%–60% charge in a cool, dry place; run one full charge/discharge cycle before first use.

Leo V. –
Support was patient with me, my body is an odd model and they confirmed fit before I ordered. Arrived correct. Already recommended it. Looked at a few brands and went with YO in the end.
Hannah L. (verified owner) –
Arrived completely flat, took three hours to charge. Would be nice if they shipped with some charge. Refund requested.
Fred O. (verified owner) –
My original died after three years. Dropped this in the Sony a6400 and it read fine on the first try, shot a full wedding on one bar left. Never heard of YO before this, but it has held up
Derek M. (verified owner) –
No compatibility warning on the Sony a6400, and the percentage actually tracks, it does not jump from forty to zero. Told a colleague about it.
Emily R. –
Fair price, real capacity, quick shipping. Nothing to complain about. Worth the money. Never heard of YO before this, but it has held up.
Andre L. (verified owner) –
capacity is honest. I got about 80 minutes of continuous 4K before the low battery warning, maybe ten percent less than OEM at a third of the price. YO beats OEM on price, no real downside so far.
Tara J. –
Compared three sellers at this price point and this had the highest real capacity. Tested it, they were not lying. First time trying YO, surprised in a good way.
Ivan K. –
Battery is fine and runtime is fine. The shell is slightly thicker than OEM so it is tight in my cage. Already recommended it.
P. Morgan –
Happy overall. Only thing, the last ten percent on the Sony a6400 gauge drains fast. Does not affect shooting.
Liz A. –
Both cells started draining fast after two weeks, warning at around one hundred frames. Maybe I got a bad one.
Wes D. –
If you shoot video, get this. No overheating on the Sony a6400 through a forty-minute take.
Erin T. –
Genuinely good value. Wish it came with a terminal cover, storage is awkward without one. Invoice came through fine.
Nikola S. (verified owner) –
Perfect as a spare. I do not shoot daily, two or three times a month, and this covers a full day. Told a colleague about it.
Owen H. (verified owner) –
I have had off-brand cells swell in two months. This one is six months in and still flat. Already recommended it
Yvonne T. (verified owner) –
Ran six hundred frames through the Sony a6400 on one charge with room to spare. I will update if anything changes.
Amanda K. (verified owner) –
Ran six hundred frames through the Sony a6400 on one charge with room to spare. Worth the money.
Hugo B. (verified owner) –
Shot sunrise at minus five, rotated two of these, no sudden shutdowns. The no-name cell I had before just died in the cold. I will update if anything changes.

Support was patient with me, my body is an odd model and they confirmed fit before I ordered. Arrived correct. Packaging was intact.
Greg P. –
Fair price, real capacity, quick shipping. Nothing to complain about. Hope it holds up.
photog_dan –
No performance complaints. Just double check the model before ordering, I got the near identical one first, replacement was quick though. Support was helpful.

Tim H. (verified owner) –
Charged it, put it in, forgot about it. That is the best thing I can say about a battery. Invoice came through fine.
