Batteries that are not used for a long time should be stored in a dry, ventilated place away from direct sunlight. Alkaline batteries, in particular, are easy to lose power because of moisture or improper storage. Therefore, alkaline batteries that are not used for a long time should be placed in a dry and ventilated place, and the shade is the best place.
In addition, batteries that are not used for a long time also need to be charged and discharged regularly. For some rechargeable batteries, after a period of discharge, it is necessary to charge in time to extend the life of the battery. It is recommended to charge once every 3 months, if the storage time is more than half a year, it is recommended to carry out a full charge and full discharge every half a year to activate the power supply and restore energy.
