Description

Technical Field

[0001] The invention belongs to the field of emergency batteries, and in particular relates to a battery with long-term standby function. Background Art

[0002] In the field of small batteries, such as No. 5, No. 7, and button batteries. At present, new batteries begin to leak slowly after production, and the theoretical storage time is 10 years, but due to environmental factors, the actual usable life is only a few years. When batteries are used in some equipment that cannot be used for a long time, such as equipment that needs to be used for emergency, disaster recovery, temporary, and sudden situations, although the actual use time of such equipment will not be very long, it needs to be in a state of readiness for a long time, which leads to the need to select batteries that can be stored for a long time, but the actual situation is that these batteries can only last for a few years before they cannot be used. In order to ensure that these devices can be used in emergency situations, it is necessary to manually replace the batteries regularly. If such equipment is scattered all over the place and in large numbers, it will be difficult to replace. Summary of the invention
