ACK-E6 on 5D2: communication error
Aug 15, 2012

A client of mine is receiving this message from his 5D2 when using the ACK-E6 AC adapter:

"Cannot communicate with this battery. Use this battery ?"

Is this normal for the ACK-E6 on the 5D2 ? I have just received my own ACK-E6 to test on my 5D3 but the error does not show up for me.

Can anyone please confirm whether or not this is a standard message when using an original ACK-E6 on a 5D2 ?

Seems to me like it shouldn't be happening.
