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).
- This is a 3.6–3.9V single-cell battery. Do not mix it with 7.2V two-cell packs or use other chargers.
- Use the dedicated BC-CSX charger or charge in-body where supported. Do not use chargers meant for other battery models.
- For long-term storage keep 40%–60% charge in a cool, dry place; run one full charge/discharge cycle before first use.

I put it on a load tester, pulled about 2200mAh out of a rated 1240mAh. Close enough for me, and rare at this price
Jess H. (verified owner) –
cell is new and it does power the camera. The Sony RX100 VII occasionally throws a not genuine battery notice, then keeps shooting.
Yvonne T. (verified owner) –
No performance complaints. Just double check the model before ordering, I got the near identical one first, replacement was quick though. Shipping was quick too.

Works in the Sony RX100 VII. Charging is a bit slow, about two and a half hours versus two for the original. I will update if anything changes.
Phil A. –
Bought this for my dad and he says it works. Labels are all English, which he cannot read. Never heard of YO before this, but it has held up.
Sarah K. (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. Already recommended it.

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. Worth the money
Lauren M. (verified owner) –
Vlogged for a bit over two hours on and off, still had thirty percent at the end of the day. Hope it holds up. YO beats OEM on price, no real downside so far.
Cynthia P. (verified owner) –
One of the two has a loose latch and needs two presses to seat in the Sony RX100 VII. Maybe I got a bad one.
Anna P. (verified owner) –
Shell had visible scratches, looked opened before. Waiting on an exchange.
Erin T. –
Support was patient with me, my body is an odd model and they confirmed fit before I ordered. Arrived correct. Told a colleague about it.
Ravi P. (verified owner) –
Compared three sellers at this price point and this had the highest real capacity. Tested it, they were not lying. Packaging was intact.
Dan B. (verified owner) –
Rating is way off. Claims 1240mAh, my tester pulled under fourteen hundred, worse than a two year old OEM.
Rob K. –
Good capacity for the money. One star off for shipping, five days instead of the two that was quoted. Looked at a few brands and went with YO in the end.
Emily R. (verified owner) –
Second order. The first one lasted about eighteen months before it started fading, so I stocked up this time. Packaging was intact.
Sam T. (verified owner) –
Ran six hundred frames through the Sony RX100 VII on one charge with room to spare. Ordering two more.
Caleb S. –
Vlogged for a bit over two hours on and off, still had thirty percent at the end of the day. First time trying YO, surprised in a good way.
Gail S. –
genuinely good value. Wish it came with a terminal cover, storage is awkward without one. Support was helpful.
Hal J. –
No compatibility warning on the Sony RX100 VII, and the percentage actually tracks, it does not jump from forty to zero. Looked at a few brands and went with YO in the end.
Leo V. –
If you shoot video, get this. No overheating on the Sony RX100 VII through a forty-minute take.
Warren B. (verified owner) –
shipped fast, arrived in two days. There is a manufacture date stamped on the cell and it is from this year, not old stock. Will buy again.
Fred O. (verified owner) –
My Sony RX100 VII is long discontinued and OEM batteries are basically gone. This one works, contacts were clean, no issues. Worth the money.
