From our cell phones and laptops to our digital cameras and handheld gaming devices, chances are most of us travel with at least one thing that requires batteries – and many of us travel with extra batteries and chargers. But before you simply toss your batteries and your backups in your bags, there are a few things you should know that can make getting through security just a bit easier. According to the Transportation Security Administration (TSA) you should:

• Not pack spare lithium batteries in your checked baggage (since January 2008, they are no longer allowed). Instead, pack all of your lithium batteries in your carry-on luggage where they can be inspected by TSA staff at your security checkpoints.
• Keep your spare batteries in their original packaging. If that packaging is not available, isolate the batteries from contact with other batteries and metal, including coins, keys, jewelry, etc.
• Pack your batteries in such a way that they do not run the risk of being crushed, punctured, or having a lot of pressure placed on them – which can cause an internal short-circuit and result in the batteries overheating.

To help keep all of your batteries together, but packed safely, it’s a good idea to pick up some packing cubes. Inside these cases you can alternate your socks, underwear or t-shirts with your batteries. This will help keep your clothes looking great and prevent your batteries from touching.
