It has been over 10 days since the battery swap out. Went flying over
the past weekend after the GPS sat for nearly a week. The clock was spot
on to the second. The unit acquired in the usual 30 seconds. I was a bit
concerned that the heat required to solder the wires onto the battery
may cause some harm (I used a temperature controlled iron with a thin
pencil tip). I will have to see if the battery hangs in there. Given the
replacement I used was 20 times the size of the original, maybe it will
last longer. Seems the original made it about 2 years.
Good Luck,
Mike
..lots o stuff snipped about how to change the backup battery.
I just did the swap on my 396. The descriptions in Terry's links give
you a pretty good overall guide, but I will add a few details.
