  1. I have 3 LI batteries for my PD150. One is the original Sony little
    one, and the other two are the largest Hahnel (Sony-lookalikes). One
    of them has decided that it ISN'T Lithium Ion (or perhaps the PD150
    has). The newer of these two batteries is OK, but the older one gives
    a warning message in the camera "For InfoLithium only" (ie, the camera
    doesn't recognise the battery as the correct type). It then shuts off
    completely. It works fine with the other batteries.

    What led up to this?: I used the camera as a remote unattended at an
    awards ceremony, clamping it to a bar on the top of the set. Because
    it would be unreachable for 4-5 hours, I powered it from the mains
    through the supplied power unit, but left the battery in place just in
    case some idiot backstage turned the power off. The manual says that
    this is OK to do (although trial and error as I write this seems to
    suggest that a power failure WOULDN'T have gone to battery while the
    plug was in -- oops!).

    When I de-riged at the end of the ceremony, I noticed that the camera
    beeped and shut itself off when I pulled the mains connector, which
    suprised me. Thinking the battery might have discharged, I put it
    into the Hahnel charger, but it showed full. It still does a week
    later, but the camera definitely isn't happy with it.

    Anyone any experience of this, or suggestions to make?

  2. It's probably dead.
    A battery can show full on the charger, but under a load it will not fire up
    a camera because one dead cell causes the whole battery to be under the
    minimal voltage limit for your camera.

    It doesn't matter if you bought both batteries at the same time.
    The individual cells in each one MAY be of different vintages. Or the
    batteries themselves could be of different vintages.
    Or the battery itself may have been damaged at some point in it's wee short

    I'd just like to add that I leave my batteries in on the unit when running
    from it's power source all the time without damage to the battery.
