Beginning January 1 of 2010 the U.S. Department of Transportation will require that all batteries are packaged so that the terminals cannot contact each other. This can be accomplished by taping the terminals with non conductive tape, bagging the batteries individually, packaging them in the original package, or placing non-conductive caps on the terminals. A subsequent interpretation letter dated November 25, 2009 exempts all dry cell batteries with a rating of 9-volts and below from the HMR, thus these batteries will not require additional packaging measures. Only chemically compatible batteries should be packaged together, and cannot be mixed with other batteries.
The US Department of Transportation issued new compliance procedures regarding battery packaging in order to prevent fires caused by improper packaging.
