5D power LED flashes even when power off

We've had this discussion before, but I thought I would raise it again since I suspect the power LED flashing when I bag and de-bag my camera etc may be contributing to power use. If it is flashing all the time when I am in motion it could be draining the power pack.

So I asked Canon Canada this:

-- hide signature --

When I move my camera, for instance into the bag or out of the bag,
the red LED flashes quite often. I wonder if this is affecting battery
life: I get less life than others report.

NOTE: This flashing happens when:

  • the switch is OFF!

  • the Canon "L" lens is secure!

  • the battery is secure!

  • the battery cover is secure!

  • the CF Card cover is secure!

The dealer has witnessed this behaviour. What could it be?


Canon's answer was:

The power switch (not indicator!) is indeed set to OFF

Or shall I just ignoire it and buy a 3rd battery pack? Opinions welcome as always.
