    Question For Blackberry 77xx and 72xx - question about battery

    Advertisement



    Hi everyone,

    I've been working on refubing a bunch of junker blackberries at work and I've noticed something weird about the batteries. Each battery has a little red stripe on a white pad.

    You can kind of see what i'm talking about if you do a google image search for "BAT-03087-003". I'd post a link, but I'm apparently not cool enough yet.


    It's to the left of the contact points.

    What is this? Is it an indicator of some kind? I've noticed on one of our non-working batteries that the entire pad is red. Is this significant in some way?

    Anyway, thanks,
    - JSmith42

    That is one of the moisture detection patches that RIM places on both the Batteries and the BB itself. If exposed to excessive humidity or moisture, it will washout an become red all over the patch.

    Sounds like you have a few that took a bath. Or at least got a little steamed up.

    Sure have. You'd be surprised at the weird places these things get dropped. Had a few take dumps in the ocean, a few into lakes and even one into the toilet. Not to sure if that last one was really an accident.

    Oh, another question... where is that second patch at? I've torn apart quite a few 7750s and 7250s and haven't see anything similar. Does it take a different form? Maybe it's just on the 8xxxx series?
