• Remove batteries if the device will not be used for several months.
"Transporting batteries can possibly cause fires if the battery terminals inadvertently
come in contact with conductive materials such as keys, coins, hand tools and the
like. The US Department of Transportation Hazardous Material Regulations (HMR)
actually prohibit transporting batteries in commerce or on airplanes (i.e. packed in
suitcases and carry on luggage) UNLESS they are properly protected from short
circuits. So when transporting individual batteries, make sure that the battery
terminals are protected and well insulated from materials that could contact them and
cause a short circuit."
