    •  OK (0+ / 0-)

      If the contacts are shorted by a metal object, the battery can overheat.

      Some (now most) compound batteries have a sensor to detect a hard short (verses a slow drain) and cust the circuit.

      Some older batteries do not have this feature and present a hazard, and bare batteries don't.

      Perhaps you may recall some Apple and other batteries sontaniously exploding or catching fire. This was cased by very fine metal fragments that were included in the manufacturing process and eventially caused shorts.

      Most batteries produced in the past 3 years or so should be safe, but some airlines prohibit them in checked luggage as a precaution.

      If you store the spare module in a nylon or plastic case it should be safe.
