This battery charges very fast with the charger purchased from Strobepro. All the function on my Canon 6D. Recognize the new batteries. Did about 300 shots and batteries are still over 3/4 charge. Looks like a great purchase.
Good so far. Works and charges with no problems in my 5D3.
Work with eos R body also, who using this battery for video long run, no heating problem also. Work like canon original battery. Buying more when on sale.
