    Watson NP-FW50 Reviews

    Drains quickly - not worth the money

    By Jim
    Rated 1 out of 5

    I was hoping the good reviews were accurate, but these batteries drain very quickly for me anyhow. In my Sony a7RII the first battery went from 100% to 32% in 25 shots and the camera being on probably less than 30 minutes. When it was at 32% I watched it drain 1% per shot I took. The second battery also seems to be draining 1% per shot, went from 100% to 96% in four shots and probably 30 seconds of being turned on. I think the 5 year old Sony batteries last longer than these, and they are pretty bad at this point. Airplane mode is turned on so that is not affecting the battery life. Pretty disappointing.

    Just as good as the OEM Sony Batteries, just cheaper

    Lasts as long (if not longer) than my Sony NP-FW50 batteries. I use them in my A6500. I have a total of 6 batteries and they get me through a full wedding video shoot no problem.

    great price and performance

    bought Watson and Sony at same time and use each equally. Sony failed but Watson keeps going. bought more Watsons.

    Not as good as the originals but certainly do the job

    They don't last as much as the original Sony batteries but for half of the price you get a good battery

    It's too soon to say how this battery will perform over time, but I bought it as a second spare for my Sony RX10 IV, a battery hog. The 5-star rating is based on the accolades from members of a photo blog I follow.

    Nice to have an extra battery

    I recently bought this battery to have and extra when I'm out shooting. I always wind up needing the second battery. These hold a charge for a good amount of time, can take a lot of photo's with one charge.

    Old battery died.

    I have had a Sony battery and a couple of others of another brand, but I have found that the Watson lasts longer than the other two - even Sony - sorry Sony. Cheaper too. Recommend this battery for the Sony a6000

    question

    I have this battery (Many of them.) One of them was left in my pants and got washed in the washing machine. Do you think I should try to charge it? It looks perfectly fine.
    Asked by: Joel
    The actual li-ion battery cells are completely sealed. There is a protection PCB inside the battery and it is possible that contaminating it with detergent could cause the PCB to fail. However the battery case is also sealed at time of manufacture and while it is possible a small amount of water got by the connector pins, the PCB is probably OK. Even if it did fail the worst thing that would happen is that the battery would not work. It would either fail to charge or fail to power the camera. There is no possibility of camera damage.

    How does this compare with the NP-FW50 made in Japan for the A7? (1000mAh vs 1020mAh)? Which will hold a charge longer?
    Asked by: Anonymous
    The OEM and Watson versions of the NP-FW50 are essentially identical, aside from the 1020 mAh version having a slightly higher capacity.
