Batteries must be protected from damage.

Battery terminals (usually the ends) must be protected from short circuit (i.e., the terminals must not come in contact with other metal). Methods include: leaving the batteries in their retail packaging, covering battery terminals with tape, using a battery case, using a battery sleeve/pocket in a camera bag, or putting them snugly in a plastic bag or protective pouch. Leaving rechargeable batteries in its charging (wall) unit is not considered protecting from short circuit.
