Batteries in carry-on or checked luggage?

I always carry on all my batteries and chargers. There has never been a problem

Eli; Your Energizers will be OK. There was a recent restriction announced on loose Lithium batteries in Carry-On luggage. Lithium batteries are rechargables, sometimes AA, but usually camcorder, camera, or laptop batteries. If the batteries are in the device, it is OK, but loose Lithium batteries may be an issue.

Lithium batteries must be a package, and cannot be put in checked luggage. Regular AA Energizers are fine.

A close friend has had batteries taken away!!! All his batteries, from his camera, MP3 player etc...
So it can happen!

A typical over reaction that has absolutely nothing to do with security.

Alkaline is OK as they don't overheat when shorted like Li ion can.

There are rules for carrying on batteries now. Any battery that is installed in a radio, clock, camera, etc. is okay. Extra batteries are limited to things like hearing aid batteries and must be unopened in their original packaging.

Depending on what you plan to bring, check with TSA online before heading to the airport.

Direct from the TSA's own website:

Effective January 1, 2008, you may not pack spare lithium batteries in your checked baggage.

You may pack spare lithium batteries in your carry-on baggage. Please see our Spare Battery Tips and How-To sections to find out how to pack spare batteries safely!

If you pack a device containing batteries, secure it against activation by locking the activation switch in the "off" position, placing the device in a protective case, or by other appropriate measures.

For personal use, there is generally no restriction on the number of spare batteries allowed in carry-on baggage. This is the case for cell phone batteries, "hearing aid" button cells, and AA batteries/AAA batteries available in retail stores, as well as almost all standard laptop computer batteries.

These are Alkaline, so there should not be a problem with TSA?

I see all the rules seem to point to Lithium batteries.

What about a sealed lead-acid battery in checked luggage?

The way it is, there is no way it can be shorted out (in a special carrier with the terminals covered).

It's a special battery for special type of GPS unit. It weighs too much for carry-on and I cannot leave it behind. (I'm not traveling on vacation.)

Bob: You may want to check with your airline about that battery, getting specific about the battery so they don't turn you down at the counter on the day of.
