Customer: Hi all and thanks for the add,iv a question,i bought a wifi wireless doorbell with the camera and it takes 2 x batteries 6800 amh in total does this meen i need 2 at 3400? or do i use 2 at 6800 each thanks.
Answer： Is the doorbell sold without battery? I guess it needs 2 x 3400 batteries. Different capacity battery's size is much different. Wrong type battery couldn't fit into your doorbell.
