Friendly reminder of the postal laws of the USA

remember you CAN NOT SHIP MORE THAN THREE CELLS LEGALLY
so no loading of flat rate boxes with a dozen or two
that is illegal and you might kill a lot of people
and if you don’t like this law then go see the postmaster general to complain
don’t think you are above the law

349.222 Secondary Lithium-ion (Rechargeable) Cells and Batteries — Domestic

Small consumer-type lithium-ion cells and batteries like those used to power cell phones and laptop computers are only mailable domestically under the following conditions. See 622 or IMM 136 when mailing batteries internationally or to and from APO, FPO, or DPO destinations.

General. The following additional restrictions apply to the mailability of all secondary (rechargeable) lithium-ion cells and batteries:
The lithium content must not exceed 20 Wh (Watt-hour rating) per cell.
The total aggregate lithium content must not exceed 100 Wh per battery.
Each cell or battery must meet the requirements of each test in the UN Manual of Tests and Criteria, part III, and subsection 38.3 as referenced in DOT’s hazardous materials regulation at 49 CFR 171.7.
The mailpiece must not contain more than three batteries.
All outer packages must have a complete delivery and return address.

LITHIUM BATTERIES
GUIDANCE
ACCORDING TO IATA DANGEROUS
GOODS REGULATION 56TH EDITION 2015

(42 page pdf, but relax, they use large fonts …)

Edit:

(DLH, p.7)

EDIT: here’s UPS:

New Lithium Battery Regulations
International: The international regulations applicable to air shipments of lithium metal batteries …
United States: The U.S. regulations applicable to air and ground shipments of lithium batteries …. for air shipments … effective February 6, 2015…. for ground shipments is mandatory effective August 7, 2015.

Are we talking loose cells? IE single 18650 cells? I’d assume this wouldn’t include proprietary packs like a 4x 18650 wired pack for a bike light, or am I incorrect?

when cells are connected together in a pack they are called batteries. cells refers to individual cells.

I willing to bet most BLF members pack cells much better than the way some chinese sellers throw cells into a package.

My math says that a 5+Ah cell (20Wh/3.7V=5.4Ah)

That's a big battery!... and you can ship three of them? Wow

Seems like a fair regulation to me. But I'm not sure how to apply it to individual (unconnected) cells.

(But I could be missing something...)

LOL this is a joke right? Do you even want to take a guess at how many cells are shipped DAILY without any issues? Want to venture at how many of those are sold via sites like BLF? I personally have had flat rate boxes of 20+ cells shipped to me on numerous occasions without a single issue. Cells shipped from over seas are something else but state side, its slightly a joke

For reference:

If you want attention, you know how to get attention.

yeah well, USPS just delivered a package to me today that clearly stated it had 7 lithium batteries in it on the details on the outside of the package.

a billion women and children starving everyday. oh no!!! he shipped 4 batteries the world is going to explode.!!!

Thank you for your service, Captain! ;)

I’m going to trust that anyone commenting here actually has read the linked documents
— or at least opened them and looked at each page, and isn’t just pounding keys.

At the very least, I’ll trust you have looked at the pictures.

Can I trust you that far? If so, no need to read further from me, because you know what you’re doing, and I”ve said all I’m going to on this topic here.

Still reading?

They didn’t make those pictures up to impinge on your freedom.

They show the pictures to explain the reasons for the detailed distinctions made — country by country — about packaging for shipment.

They’re not trying to take your tobacco products away. The regulations address a known risk of losing an aircraft full of people. Not the only risk. Can’t get them all.

So you got a package.

Did the package travely by air mail? If so, was it carried on passenger aircraft? or carried by cargo aircraft? or carried by ground transportation?
That’s what the labels affect — how the package travels.

The regulations differ, and the effective dates of the regulation differ, and the uses of the labels differ.

Does the package contain lithium-ion, or lithium? You’re flashlight people — you know that the chemistry, and the risk, and the regulations, differ.

Did you send the package?

The responsibility will lie with the shipper — once the regulations are in effect at the point of origin.
Once the regulations come into effect, your odds of getting a package will change if the shipper’s proven untrustworthy.

Remember how for a few months, lots of battery shipments got held up? We don’t always hear about accidents, but something changed in China not long ago.
They don’t publicize problems there readily.

You realize the effective dates above haven’t all even happened yet, right?

Folks, it’s easy to go all high-principle-ultimate-individual-freedom when you’re not responsible for other people’s lives and property.

But is keyboard campaigning against regulations written to address a real, known problem that’s caused real fires on real aircraft the best use of this particular public forum?

You know how people feel when an aircraft goes down? And you know air mail — if not labeled for ground transportation or cargo air travel — often goes on passenger aircraft.

Just sayin’ —- sometimes, people get the attention they deserve.

Sometimes they call attention down on other folks who don’t deserve or need that attention.

I’m sure there’s an appropriate place to go on about this at length.

This ain’t it.

We know the problem — it affects us too: fake batteries, unsafely made, shipped by the same liars who made them or by people who sold them not caring they’re fake.

There are no libertarians on airplanes these days.

Done with the topic, myself. Consider your words.

Here's the truth about captainmike.

Right now he has 17 posts.

The vast majority of those posts are about the safety of 18650 cells and batteries.

11 of his posts are in 18sixfifty's sale thread.

The majority of those posts are of captainmike crapping on 18sixfifty (who I believe is a great asset to BLF.)

Let's face it, captainmike is a one–trick pony, and not the good kind that greets BLF members and is obsessed with Resident Evil. ;)

Under medicated. He definitely has some paranoia. Shame to be new here and he is threatening to get seasoned members in trouble by turning them in. Doesn’t make much sense. Yes there are risks associated with shipping lithiums that can be lessened with proper packaging. 18sixfifty does an excellent job packaging them and I have no problem with what he does. From reading captainmikes previous post, he’s a little TOO paranoid and should mind his own business dealing with 18sixfifty. I have a problem with somebody with 17 posts that appears to be intentionally stirring stuff up.

I think 99% of members agree. +1
