hi all.
I left a battery in my Mark III with the camera turned on in Standby mode, and one day when I went to use the camera, discovered that the battery had gone flat.
I placed the battery into my LC-E4 charger and a few moments later, the charger's LEDs all began to flash. the charger was unable to charge the battery. I bought another battery and the charger was unable to charge that one too. my friend's LC-E4 was able to charge both batteries.
I wonder if the very-flat battery somehow over-stressed one of the components in the charger.
Canon has confirmed that the charger no longer works (both battery compartments), but their policy does not permit them to examine and repair its components.
the charger is very expensive to buy. does anyone know who might be able to examine the components of the charger and repair it? hopefully, it's as (tongue-in-cheek) -simple- as replacing a capacitor or transistor.
unfortunately, the charger was less than 2 years old, and only used once every 2 or 3 months. the components could not have been very high quality to fail so 'quickly'.
cheers,
Gregory
