The service life of lithium batteries is about two to three years. In other words, the cycle life of lithium batteries is about 500 times.

1. Cycle life refers to the number of cycles of power and complete discharge that a battery can withstand before its capacity drops to a certain specified value under a certain charging and discharging system. After each cycle is completed, the battery capacity will decrease slightly and the battery's lifespan will also decrease. The cycle life is not equal to the number of charges. If the battery is charged multiple times in a charging and discharging cycle, the actual loss to the battery is a cycle.

2. Lithium batteries are batteries that use metallic lithium or lithium alloys as negative electrode materials and non-aqueous electrolyte solutions, so this type of battery is also called metallic lithium batteries. Unlike other batteries, lithium batteries have the characteristics of high charging density, long lifespan, and high unit cost.

3. Be careful not to mix the battery with metal objects to avoid metal objects touching the anode and cathode of the battery, causing short circuits, damaging the battery, and even causing danger. Lithium batteries should be stored in a ventilated and dry environment, away from high temperatures and sources of ignition, to prevent high temperatures and humidity from affecting the performance of lithium batteries and corroding their surfaces.
