How to check if my battery is an original one?

Ok, but here's the problem:

1. the system is ok and it's been checked on Apple's website.

"If a product that is dangerous goods or that contains a dangerous goods component (e.g., battery) is subject to a safety recall related to the dangerous goods, it must not be carried aboard an aircraft or in baggage unless the recalled product/component has been replaced or repaired or otherwise made safe per manufacturer/vendor instructions."

So...this is not the case, because there is no need for a repair in my case.

2. Apple won't replace my battery if it's not one of the damaged or potentially risky ones.

3. I can't keep my Mac at home all the time from now on! :))

There has to be a better option.

Nonetheless, you made some very good points here... I honestly don't know what to do. And, again, not just for this trip. But for all the other trips when I will need my laptop.

Any idea if there is any difference between the laptop being turned off vs being on? Does it still pose a risk when it's off? I mean, in my case, it shouldn't pose any risk since it's not one of the damaged batteries. But just saying. Just to be 1000000% sure, does that actually make any difference?

Sadly, its more complex than that! >Any< MacBook will be suspect! Think of it this way I've got three exact boxes that are physically the same in every way. One has a bomb which one is it? Thats the conundrum!

The guy who is scanning your bags or hand checking can't tell which is the 2015 models from the others and then he still won't be able to tell which ones have the good battery vs the ones that don't.

Again, remember this is just happening so we just don't know what is happening at the airports. Its now a question are you going to get nipped or are you able to sail through. What happens if you get nipped? I would hope to have a plan B just incase. Will this be a long term issue? I just don't know.

I tend to travel light with just my iPad, and if I'm going somewhere distant that I need my photo gear I ship my gear to where I'm staying as I know it will be a big mess showing up at the gate. There are a few services that offer this, less to worry about at the airport.

Frankly, I would turn the system fully off as you don't want to waste the charge.

You do tend to let your system run hard on battery hence the 500+ cycles in its short life in your care. I would strongly recommend to be more aggressive not letting the battery discharge below 20~30% if you can avoid it. Otherwise you may need to replace your battery more frequently.

You may want to consider one of the external battery packs that offer MagSafe connectivity. Or, think about getting a newer MacBook which has USB-C so you can leverage the USB-C based external battery packs.

@danj Again, very good points... And yeah, it's kinda sad. Cause, you know, any Li-Ion battery can be a fire hazard. Even those power banks we get for our phones. And I see no one complaining about those. I mean, what are we gonna do? Leave everything that has a battery in it at home, just in case? Everything is based on Li-Ion batteries nowadays. Even our camera gear. So, basically, you won't be able to take any battery-powered electronics onboard? :)) That's...not good.

As for your question, yeah, you do have a point. But..all I'm saying is that, in case they want to check wether or not my particular machine is safe, they can just do what I did. Check it against the Apple site.

Also, how many MacBook Pro 2015s are still out there? I bet at least a few millions? Are you telling me that suddenly all of those people will have to leave their Macs at home, just in case? Cause this is crazy. :))

Samsung yanked their cellphones when they kept failing. And I know of a few people who had their phones confiscated one flying back from Europe to the states. They even killed any still out in the in the wild with a firmware update.

Give it some time lets see where things go. You are just caught in the worse of timing. If you need your laptop can you ship it? Can you rent one there? Or borrow one? Then you only need to carry an external drive with your stuff.

Otherwise... You did say you needed an iPad didn't you ;-}

Yes, this is a pain! Don't freak out yet.

@danj :))) OMG... yeah... Don't freak out...yet. :)) Best advice ever.

I don't have an iPad unfortunately. But yeah, now would have been a good time for one. And yeah...I kinda do need my laptop... I could ship it...but I don't have the original box. And I'm kinda afraid they might damage it in transport... I mean, I can try packing it in a bunch of bubble wrap. But...other than that...

Now, rules in the US might be a bit harsher (at least right now) than they are in Europe. I mean, today I called the airline and they were not even aware there are issues with the MacBooks. They sent me to ask the check-in guys... :))

I'm not traveling that far. It's just from one part of the country to the other. So yeah...I could ship it there and from there...in case there is no better option.

This serial number seems to show up over and over across multiple manufacturers on multiple battery models; do a Google search for "C01514309YEF90MA4" and you'll find plenty of examples. I've seen it on two "genuine Apple" A1322 batteries I purchased this year from different sources, both flashed as being made by SMP (Simplo). Unless all these companies started flashing all their respective batteries with the same common serial number (instead of generating unique serial numbers and matching the exterior serial number on the battery case, like my original battery), I'm assuming it's either a system "placeholder" generated by the OS or a sign that these batteries might be counterfeits, made by a common company. I sent a query in to Simplo for clarification before deciding whether or not to demand a refund and send my latest battery back to the seller as a suspected counterfeit.

@gregmarksc38462 Have you heard back from Simplo regarding the "C01514309YEF90MA4" serial?

@niemand Not a word. Can't say I'm surprised.

I ended up having to keep the last battery I ordered (for lack of a better alternative). Still concerned it might not be up to spec, so I've been really careful not to leave it charging any longer than necessary, but so far it hasn't glitched.
