New TSA rules for Lithium Batteries on flights, effective 1/1/08

The Transportation Security Agency (TSA) has new rules, effective Jan. 1st, that apply to 'spare' lithium batteries that you can carry on U.S. airline flights. You can read the complete new rules at and more info at

Effective January 1, 2008, spare lithium batteries - extra batteries not installed on devices - will no longer be allowed in checked baggage. Spare lithium batteries may be packed in carry-on baggage and lithium batteries installed in a device may be packed in either checked or carry-on, as long as the battery is installed in the device.

Here is an except from their web site:

Effective January 1, 2008, the following rules apply to the spare lithium batteries you carry with you in case the battery in a device runs low:
Spare batteries are the batteries you carry separately from the devices they power. When batteries are installed in a device, they are not considered spare batteries.
You may not pack a spare lithium battery in your checked baggage
You may bring spare lithium batteries with you in carry-on baggage – see our spare battery tips and how-to sections to find out how to pack spare batteries safely!
Even though we recommend carrying your devices with you in carry-on baggage as well, if you must bring one in checked baggage, you may check it with the batteries installed.
The following quantity limits apply to both your spare and installed batteries. The limits are expressed in grams of “equivalent lithium content.” 8 grams of equivalent lithium content is approximately 100 watt-hours. 25 grams is approximately 300 watt-hours:
Under the new rules, you can bring batteries with up to 8-gram equivalent lithium content. All lithium ion batteries in cell phones are below 8 gram equivalent lithium content. Nearly all laptop computers also are below this quantity threshold.
You can also bring up to two spare batteries with an aggregate equivalent lithium content of up to 25 grams, in addition to any batteries that fall below the 8-gram threshold. Examples of two types of lithium ion batteries with equivalent lithium content over 8 grams but below 25 are shown below.
For a lithium metal battery, whether installed in a device or carried as a spare, the limit on lithium content is 2 grams of lithium metal per battery.
Almost all consumer-type lithium metal batteries are below 2 grams of lithium metal. But if you are unsure, contact the manufacturer!

Actually, it's not a TSA Rule, it's one handed down from the Department of Transportation. It's just that it's the TSA would will be enforcing this rule.

this doesn't make sense to me.

batteries that are in a device are OK, checked or carry on.
spare batteries cannot be checked, but can be carried on?

Part of the reasoning behind not allowing them loose in checked baggage is that the fire suppression systems in the cargo bins cannot put out that sort of fire. There was a UPS flight about two years ago that caught fire that may have been caused by lithium batteries in a shipment of laptops (The final NTSB report on the incident has yet to be released).
UPS Flight 1307

As long as they are in the passenger cabin, there are fire extinguishers onboard that can put out that sort of fire.

that's just great.. now we gotta think even harder about packing before a casino trip.. this is the time I like to reserve my brain to study house advantages, odds and player strategy.
