Vivitar NP-FW50 Battery for Sony

Swapped out the original Sony battery for this Vivitar in my a7ii and it holds the charge just as long during a full day of shooting. The fit is snug and secure, no rattling or loose connection at all.

Bought this as a backup for my a6000 and it holds a charge just as long as the original. Slips into the camera body with no wiggle, charges up fine in the stock Sony charger. For the price, having a spare NP-FW50 in the bag is a no-brainer.

Picked this up as a backup for my a6000 and it charged my old FW-50 batteries right up, no issues. The charger is compact enough to toss in my camera bag, and I like that I can top off two batteries without hauling the whole kit around.
