  • Sony NP-FS11 Batteries: After the Aftermarket

    The batteries I rebuilt for our much-beloved Sony DSC-F505V camera back in early 2010 have faded away with constant use. Having already sawed the cases open, rebuilding three of them didn’t pose much of a challenge; this time I added a short tab of Kapton tape to help extract them from the camera socket.

    Three batteries seems to be about the minimax for ordinary use:

    • One in the camera
    • One in the carrying case
    • One in the charger

    You (well, we) can’t keep track of more than three: it always seems one battery gets overused and another gets lost in the dark. We’ll see how three works in practice; there’s a set of six more raw cells lying in wait.

    The new batteries produced these results on their first two charge-discharge cycles:

    One battery didn’t come up to speed on the first charge, but after that they’re all pretty close.
