I did a long research in to this several times. I don’t know where you got your “Shipping carriers and customs tend to disagree” from, but your source, if any, is wrong.
I’m sure if you package the battery, on it’s own, the way your State and destination require it, you won’t need a hazmat suit to do it.
One just needs to be able to read instructions.
Again, it depends how You ask shippers/carriers and customs about shipping batteries.
One of the selling features that had me buy the L5 was the ability to purchase and easily install a battery. Turns out, that was just more Carny Barking.
I just grabbed a old flip phone from junk box. It was released in “Release Date, May 2011”. User removes cover easier than L5, removes old battery and inserts new battery. I may order the battery from US and they will ship it to Canada. It’s not a new thing.
Purism should let potential customers know that a battery replacement for Puri out-of-country is not durable by Purism.
The part you say Pursim is responsible to certifying people to handle batteries must be a opinion, not a fact.
Purism must already know the battery specs such as Wh rating, Lithium weight etcetera. Too, specifying the package is for ‘Ground Shipping Only’ will make a big difference in whittling down the extra for air regulations.
I had the opportunity to get a spare battery when the phone went back to Puri but the requirement that the battery be sent back inside (no good reason why) cancelled the idea of putting a new one in.
The ads are correct. The battery is replaceable. But just try and get a L5 battery outside the U.S.
FedEx, DHL, UPS, Purolator, all have sections on their web sites listing instructions on how to package the battery to be shipped. All the sender needs is the ability to read and follow instructions.
One may pick up the proper packaging and labels from any of the carriers.
It is doable. The process just needs a little organizing and homework done to implement it.
Side but close situation:
If I walked up to your store front, and asked to buy 10 batteries They’d be handed to me inside the store and I walk them out. Will Purism sell them to me?
