Be warned that batteries can be confiscated at the airport. TSA rules apply in the US but other countries can and will make up their own rules and enforcement.
I just left the Philippines for the US and the Philippine National Police attempted to confiscate the AAA batteries for my MP3 player. It took about 20 minutes of arguing, name dropping, and finagling in ways the average tourist doesn't have access to to get them back. (The illogic was that they weren't concerned about the battery in the laptop)
I really would have hated to see what they would do with the battery from the canister light.
Just remember that TSA rules are a minimum security measure for flights flying to or from the US. Countries can impose a stricter regulation.
