Hello, my first post. I am worried about the battery in my early 2011 MacBook Pro 13", that was replaced by an Apple authorised service provider here in central Vietnam. I am worried that it is fake. It is supposedly a DP brand and has the odd serial number of 012345678ABC. On battery power it has shut down twice at around 50%. After the shutdown, the Coconut Battery app says the has around 70% of original capacity on the first instance and 47% on the second instance. After recharging the capacity goes back to just over 100%. I didn't get a receipt or case number from the service provider, but I paid by credit card. Will Apple take responsibility for this if it proves to be fake or defective? I am no longer in that major central Vietnam city as I am travelling to Ho Chi Minh city. I am worried this battery could be a fire hazard.
