    So I changed out the EDMU battery following the video instructions on EdgunWest.

    Pop the cover with compressed air

    Gently extract EDMU circuit board

    Depress brass battery clip

    Remove battery.

    Insert new battery..good EDMU lights up!

    Orient the circuit board and snap the cover back on

    Test.  Replace the tape and screw on end cap.

    I was thinking how easy that was and laying next to the bad battery…

    Argh!  WTF is the little black plastic thing??

    The little black plastic thing was glued to the circuit board to protect the 4 wires.

    You can hot glue it back in place.

    Avoid cheap CR2032 cells, Energizer brand in this case will last the longest.

    Or legit Panasonic / Sony if you can source them. That battery is not fun to replace, it pays to get the best that you can find!

    Thx Jack.  It does look like something to hold or separate wires, though my part looks slightly different than the one in your pic.  

    @heavy-impact and mtnGhost

    Yep.  The Maxell pictured is the battery that died.  Replacement is an Energizer.  

    I'll hang on to the part and glue it back on when the Energizer goes bad.   Kind of a pain to blow the cover off with compressed air…that's probably what knocked the part loose in the first place.  Must be an easier way to get the cover off and gain access to the circuit board.

    I'm curious if yours came with a battery? Mine arrived the other day and did not come with a battery.  It was no big deal to buy and install one.  I tested it with the cover off and still no worky.  Pulling the battery and reinserting got it up and running.  I found a copy of the EDMU manual and it said this could happen. Shorting pins 1 and 4 on the card edge connector could also fix hung code if the battery insertion interrupted the initialization.

    OK I was looking at the part the wrong way.  I see how it would go.  Doh!

    @joer

    I purchased my R5 used on the AGN classifieds so it had a battery installed.  Not sure if the previous owner swapped it out.  For me it lasted around 8 months.  We'll see how long the Energizer goes.  As soon as I popped the battery in, the EDMU went thru its startup routine.  I guess the loose part wasn't critical..yet.
