    OK, I see- that is in fact one of the part #'s that we have received. The giveaway was when I realized that the picture you attached is one I took... :wink:

    So is this a viable battery or not? If so where can we get hold of one and what price are they? Ron, in another thread you spoke of an upgrade, do you have details of that before i throw this unit out?

    I'm not sure what battery Greg is locating. It could be viable if there is a thermistor present, though the connector might need to be soldered on. I've replied in more detail in our conversation re. getting one of the actual batteries.

    Thanks for all the help, I purchased a battery from china and switched the old thermistor onto the new battery. Bingo - charged and now doesn't discharge when charging cable removed. i do have one final question before I go diving. The small "bead " on the back was not removed during the process. do i need to do anything to ensure water seal integrity?

    If you didn't take it off it's not necessarily a problem. Our instructions do say to remove the little ball. It's a vent to allow for a safe release in case the battery starts to off-gas, which as far as I know has never happened.

    The reason for removing it is to release pressure when you close the battery door. There is a risk of displacing the O-ring from its intended seating surface if you try closing the battery compartment against too much pressure. The battery door O-ring should be well lubricated.

    Removing the ball will prevent any risk of displacement, then you glue the ball back in place with silicone. You can probably tell by feel if you are getting a gas-tight seal when you close the battery door.

    Hope this helps.
