Related Questions and Answers

Q: 1. How does this compare to the Panasonic battery?

A: I have found the Watson batteries to be good substitutes for the original Panny's. A couple of caveats would be, a) don't let them sit around too long between charges, &b) toward the end of charge they can just konk out w/little warning, while the Panny battery seems to carry the charge longer. These claims from my experiences are especially applicable to shooting videos. Thus I won't knock them especially when looking at their cost compared to Panny batteries.

Q: 2. Is there a Watson charging plate for this battery? I see there's an answer recommending a plate but it appears to be for the wrong battery, a battery ending in 13 not 31.

A: No, I'm sorry, there's no Watson charging plate as of May 2021.

Q: 3. Will this work with the GH5?

Q: 9. Does B&H sell a dual battery pouch that will fit two DMW-BLJ31 batteries? Ruggard battery pouch (B&H # RUBPR2SLRB) is too small

A: The size of the Watson DMW-BLJ31 Lithium-Ion Battery Pack (7.4V, 3500mAh, 25.9Wh) poses a problem for our dual-battery pouches such as the Ruggard Battery Pouch for 2 DSLR Batteries (Black), B&H # RUBPR2SLRB. I think the best option would be a larger belt pouch such as the ARRI Camera Assistant Belt Pouch (Large), B&H # ARK20013016.

Q: 10. Is the tight fit a potential issue once the battery warms up with normal use? I'm concerned about the battery getting stuck inside the camera.

A: A battery will swell when extremely hot--you should not allow the battery to be that hot in any case. When operating in a hot environment, you should check the battery and give it time to cool down, if necessary.
