Watson NP-FW50 Lithium-Ion Battery Pack (7.4V, 1100mAh)

The battery works perfectly and honestly I notice no difference between it and the battery that came with my ZV-E10. The charger, on the other hand, is worthless. It does charge the battery, but the moment you disconnect it from power it drains the battery in an hour. I guess they've never considered a blocking diode. So the charger is in the trash, but the battery is in my camera.

Here's the deal. Have a mess of batts holding various levels of charge. The plan is buy one official Sony and 2 generics for the price of a single Sony. Place a dual charger in the pocket with a power-pack (1/3 smaller than the beast shown here) and I can shoot all day bringing but 3 batteries total. - - - - - The 2 Watsons I bought will shoot 1:34 continuous (I eliminated the 30 min record brick wall using the 'hack' allowing the 7Siii to do so) until depleted which is identical to the official Sony. Time will tell whether they age the same rate as the Sony one but for now everything's on a level playing field, battery wise. - - - - - Unless mine's defective I advise buying the Watson dual charger. It takes 6 hours to charge batts whereas the generic Neewer (came with 2 batteries) only takes 2.25 hours.
