    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.

    Thanks, and Happy Holidays!

    Have you determined that your battery is dead or not taking a charge? There are a number of things that can mimic that condition. Batteries typically fail gradually, by holding less charge over time.

    Atomic does have and sell the batteries- it ate past they would sell them through their dealers. Let me know if you have any questions.

    Hi Ron.

    Thanks for the quick response. I've gone through the threads here and did several of your recommendations including the battery pull, re-installing firmware, etc. I'm going to try a complete re-bleed of the battery, and then another firmware re-install, and see how that goes. I don't mind sending my unit in to Atomic, if that's what it takes, as I have no immediate dive trips planned (sadly). I heard you mention rumors about a new wrist unit and trade-in possibility, so I might consider a new unit (mine is almost 7 years old now), so we'll see.

    Thanks again for your great support.

    - Ed.
