Hi everyone! I'm still around, though not much here.
 
I hope you can help me with this.

I purchased a Canon T6i in December. Days ago I bought a spare battery, Canon brand, in B&H (shipped to a friend who was in the USA).

I charged this battery two times, I believe. Now I put it in the charger and the orange light is blinking. I thought it could be poorly positioned in the charger, so I removed and placed it again. No luck.

I could not find in Canon's Knowledge Base anything other than the regular charging instructions (https://support.usa.canon.com/kb/index?page=content&id=ART161444). I found that another model had a similar problem (http://www.canonrumors.com/canon-lp-e6-product-advisory/), but I don't know if this is the same thing really.

The charger and the battery have not suffered any accident such as being spilled with water or whatever.

Any ideas?

I didn't try the other battery, which is charged, to see if the blinking happens with it. I want to preserve this as I am away from home right now.

Thanks!

I'd say that's it... Canons typically flash once when they're really low, twice when they're on the way, three times when they're nearly there and solid green when they're done.
