Here is an Email I received from Canon I would like to share this with all you Canon owners
Thank you for using Canon products.
Affected Product
Canon LP-E6 Battery Pack when used with the Canon LC-E6 Charger
(Compatible with Canon EOS 5D Mark III, EOS 5D Mark II, EOS 6D, EOS 7D, EOS 70D,
EOS 60D, EOS 60Da)
Symptom
In rare cases, the orange lamp on the Canon Battery Charger LC-E6 will blink rapidly at regular intervals when the Canon Battery Pack LP-E6 is inserted. In such cases, charging the Canon Battery Pack LP-E6 in the Canon Battery Charger LC-E6 is not possible.
Battery Condition Charge Lamp
Color Indicator
Standby for charge Orange Blinks once per second
Communication error Blinks rapidly
0 - 49% Blinks once per second
50 - 74% Blinks twice per second
75% or higher Blinks three times per second
Fully charged Green Lights up
This symptom may occur when a Canon Battery Pack LP-E6 has been discharged due to being unused for a prolonged period of time, such as when it is first purchased.
If this occurs, please follow the procedure below.
Procedure
1. Plug the Canon Battery Charger LC-E6, with the Canon Battery Pack LP-E6 inserted, into a power outlet.
2. Wait for 20 seconds.If during this time the orange lamp blinks once per second, please continue to charge the battery until the green lamp lights up, which indicates a full charge. At this point, the battery is ready for normal use, and there is no need to follow the remaining steps.
If during this time the orange lamp blinks rapidly, please move on to Step 3 of this procedure.
3. If the orange lamp blinks rapidly, remove the Canon Battery Pack LP-E6 from the Canon Battery Charger LC-E6.
4. Wait for 10 seconds.
5. Reinsert the Canon Battery Pack LP-E6 into the Canon Battery Charger LC-E6.
6. The Canon Battery Charger LC-E6’s orange lamp should begin to flash slowly (once per second) and charging will begin.Please note: If the orange lamp blinks rapidly again, please repeat steps 3-5 above. If, after a third attempt, the Canon Battery Pack LP-E6 does not charge, please contact the Canon Customer Support Center for assistance.
7. Charge the Canon Battery Pack LP-E6 until the green lamp on the Canon Battery Charger LC-E6 illuminates, signifying that the Canon Battery Pack LP-E6 is fully charged.
Use of non-genuine Canon Battery Packs
The situation may also occur when attempts are made to charge non-genuine Canon Battery Packs in the Canon Battery Charger LC-E6. However, the procedure provided above does not apply to the use of non-genuine Canon products.

StraightShooter, I just got the same email from Canon. I have 2 cameras that use the LP-E6 batteries, I have 4 of batteries, 2 of the chargers and have not had any issues. Looks like the issue is trying to charge a 'dead' battery or an off brand one. TNmike

I got the same letter and have the same battery set up. I even use aftermarket batteries. Never a problem.

I have this same set up. Haven't heard anything from Canon nor have I had any problems.

This is exactly what happened with 2 of my non-genuine Canon batteries and is why I say always buy OEM or genuine batteries.

I wonder if the cheap aftermarket batteries have those problems.

Hey Jerry I have a few sets of Canon and some cheap aftermarket batteries. Never have had a problem with the charger. Hope I don't know.

I've never seen a performance difference using name brand or "those others."
