It is 3200mAH,not 4000mAH! Panasonic has producted 3400mAH rechargeable 18650 battery,I haven't heard of 4000mAH yet.
By the way ,you had better not post the link here,it is prohibited according to the CPF rules.I have just read it.
Yes sir, I'dont do that next time,
Maybe i got the wrong news about panasonic 18650 4000mAh
Sorry!
