Two battery limit in carry-on...

I'm off to Portugal next week and will be taking a bike with SRAM XPLR so needs an AXS battery, I wanted to take a spare to but also need to take a power bank. Are airlines super strict on the 2 battery limit (EasyJet in my case) in carry-on? How do people cope with a bike with front and rear mech and something like an electronic dropper or a flight attendant? I guess I might just play it safe and buy a power bank when I land.

No - I think the 2 battery limit only applies when the batteries are between 100 and 160wh in size. I dont think they really care much about how many small batteries you take.

 

I just got back from spain (flew with easyjet) with the following batteries

- 2  x drone battery

- 1 x  phone (containing a battery)

- 1 x 160wh ebike battery

- 1 x mini games console with battery

- 1 x headphones with battery

- 1 x usb power bank

- 1 x garmin with battery

etc

You can carry up to 20 batteries IIRC, but size counts^^

Read up, package them well to prevent short circuits and declare them at check-in

Cheers, maybe I'm reading it wrong as it's a bit ambiguous for <100wh batteries, will have covers on the AXS batteries so hopefully that's enough (also specifically talking about loose batteries, not ones in devices)

If you aren't sure then ask EasyJet, but it looks like you can have batteries in devices in hold baggage and then carry spares.

IANAE, so ask them rather than ruin a holiday 😎

I've never had my carry-on searched (at the gate, by the carrier) nor seen that happen to anyone else - how would they know how many batteries you've got?

 I'm fairly sure you're interpreting it incorrectly, the restrictions on carry-on only apply to batteries >100Wh. 

We also used a lot of these, ~180Wh batteries that split into two to get around the regulations (see also the simplified table). I'm always surprised e-bikes didn't evolve along similar lines. 

Also see the table on page 6 here for the general guidance. I don't know if they can/do restrict things more tightly than the default yes/no unless it's asterixed.

It's security that will check, not the airline.

Airport security don't give two shits (or even know) about what the carrier say you may take on the plane. This is not the same thing as e.g. the 100ml of liquid situation.

I'm compelled to reply here, being that I work for an Airline. 

 

This is totally wrong.

Limits on batteries and other dangerous goods are LAW. 

 

https://www.legislation.gov.uk/uksi/2002/2786/contents/made

 

This is very serious, when you make that declaration at check in that you don't have a knife, gas canisters, fireworks, mercury, drugs, or lithium batteries outside of the allowance, this is not something to laugh off. 

Dont take the piss. If you get caught, it will be serious.

No, what Snotrag said.

It is in fact the same thing as the 100ml liquid situation.  

For the avoidance of doubt the rules are:

Per person:

15 portable electrical devices (laptops, phones, watches, Garmin, etc)

20 spare batteries of any type <100Wh

2 spare batteries <160Wh

Spare batteries for mobility devices as long as they contain <8g of lithium (typically 100Wh)

Within reason, you won't have to worry about a spare AXS battery unless you have a hugely abnormal number of electric devices in your hand luggage.

I might be mis-interpreting the regulations, but it was my understanding that security only limit you to 2 batteries between 100-160 Wh (which are big batteries - far bigger than an AXS or normal phone booster battery) in your carry-on, but you can take more smaller batteries as you like (as long as they're compliant i.e. safe)

Easyjet have their own separate restriction on 2 "spare" (i.e. loose) batteries regardless of capacity ("Devices must be 12 V or less and 100Wh or less. A maximum of 2 spare batteries may be carried.") but since they don't look in your bag, how would they know?

Putting all of the points above to one side ... can't you pack the batteries with the bike?  Presumably you aren't carrying that on?

It's more restricted in checked/hold luggage - you can't have any disconnected batteries there from what I see in the rules. I could leave it attached to the bike and just charge it the other side (as I assume it will wake up with the planes movement and drain, although not sure how much and it's only a 2.5 hour flight). I will have an electric pump and some other devices with lithium batteries in hold luggage but that's OK from what I can see.

The EasyJet wording is (in a section with cabin luggage ticked and hold luggage crossed):

All spare batteries, including lithium metal or lithium-ion cells, power banks or batteries

Lithium ion batteries for portable (including medical) electronic devices, a Wh rating exceeding 100Wh but not exceeding 160Wh. For portable medical electronic devices only, lithium metal batteries with a lithium content exceeding 2g but not exceeding 8g. Maximum of two spare batteries in carry-on baggage only. These batteries must be individually protected to prevent short circuits.
 
 
On the one hand it sort of implies that entire section is only relevant if the battery is 100Wh-160Wh (none of the 3 I'm taking even exceed 100Wh) but then why does the section title say "All". And then the sentence "Maximum of two spare batteries in carry-on baggage only" if taken standalone implies a hard limit of 2 loose batteries regardless of capacity.
 
I've emailed EasyJet CS but no clue if or when they'll respond. If they don't I'll take (in cabin luggage) and declare all 3 and if it's an issue I'll leave the power bank with them (as that's only £15 anyway and easy enough to replace at my destination), assuming I can just leave it...

You don't have to declare or ask anything. Just put them in your hand luggage, and put them through the security scanners like everything else you'll be taking in hand luggage. If the rules of the airport say you need to remove electronics and liquids from the bag and place into a separate tray for scanning then do that, otherwise leave in the bag. 

There will be no issue as long as you don't have more than two >160wh.
