So, Bought Sony 4K camcorder Last year! Middle size battery is $ 80 at Best Buy! This Large battery has more then Twice the battery life! It cost`s some where in the area of $32 for 2 batteries! That is great! The only thing the batteries are not made by Sony! They fit most Sony camcorders!

Although I have only at this point of weeks either been good replacement batteries for the previously owned batteries that I had for 3 year for the Wasabi Power Batteries finding that the 4-Hour time is excellent for the videoing I need to do in the documenting I need to accomplish would highly recommend these batteries

Pareciera no tiene la misma duración de su equivalente original pero su rendimiento en horas es bueno. Excelente producto teniendo en cuenta calidad y precio.

Pros- CheapCons- Cheap - only lasts half as long as genuine Sony battery, and one of the BM batteries lasts one hour less than the other identical battery- Slightly longer than equivalent Sony battery, so won't fit inside some Sony cameras with internal battery compartmentsI'm not getting the expected capacity and runtime that was advertised. The BM batteries say that they have a 32.4Wh power capacity and I'm comparing them to a Sony battery with a 25Wh capacity (Sony battery is smaller and less capacity).When I tested your BM batteries against the genuine Sony battery, I received these results (76ºF ambient room temperature):BM BM-NPFV100 battery record time: 78-155 minutes Sony NP-FV100A battery record time: 286-300 minutesEven though the Sony battery has 23% less rated power capacity than the BM battery, it lasted more than 1.8X longer. The same camera (Sony PMW-X70) and recording media was used. It was a controlled environment where I let it record continuously to test the battery. All batteries were fully charged using the same Sony battery charger and indicated at least 98% full charge when installed in the camera.The other downside is that the BM batteries are ever so slightly longer than the equivalent Sony batteries, which means that they won't fit inside some Sony cameras with internal battery compartments. I have one particular camera that is rain proof, so there is an internal battery compartment to protect the battery from water. This BM battery won't fit inside because it's too long by a fraction of an inch.I would only buy this battery if you are ok with getting about 25% to 50% of the Sony NP-FV100A battery and you don't need to use this battery for professional purposes or for any once-in-a-lifetime event because the two batteries that I received fell short of my low expectations and are also highly variable and unpredictable in terms of how long each of them lasts.

Fast delivery, item was a described, works great

I ordered one package, which arrived with one battery not holding a full charge and dying early. I returned it for a replacement which appears to work fine. Very happy with the product and vendor.

These had long battery lives and ended up giving me about 8 hours worth of video/film per battery on a Sony HandyCam. They were acceptable for the price.We will see how long they last, but so far so good.

Works great
