Storage

Store the batteries in a stable position, and away from any metallic or other conductive material ( including dropping material).

Store the batteries starting from the fully charged state.

When storing the batteries, be sure to remove them from the equipment, or disconnect them from the charger and the load. Keep them in a place where the temperature is sufficiently low.
* When the equipment that incorporates the batteries does not have a circuit (or device) that prevents over discharge (including week current), or if the batteries are stored without being disconnected from the equipment, the batteries may be over discharged and may not recover their capacity after charging.
* If the batteries are not stored at low ambient temperature, their self-discharge increases and their performance deteriorates. And if they are stored in a place where dew condenses, their terminals may corrode.

Charge the batteries, at least once every six months during storage below 25℃(77F). Use the charging method is shown in “Charging Methods”. The interval of this charge must be shortened to half with every rise in temperature of every 10℃ (50F).
* Their self-discharge increases twice by temperature rising of every 10℃ (50F). If they are stored for a long time in a discharged state, their capacity may not recover when recharged after storage.
* If the batteries are stored for a long time (1-2 years at around room temperature), the capacity may not be recovered fully. In this case charge the batteries longer than normal by 12-15hours at the condition of the cyclic operation.

Batteries should be used as quickly as possible.
* The batteries gradually deteriorate during storage.
