Because of its large capacity and no memory effect, lithium batteries are used more and more widely in modern production and life, especially those products such as mobile phones and computers, which are not equipped with lithium batteries! In general, some mobile phones will be equipped with a spare battery. If the backup battery is charged, how can it be saved to ensure that its energy is not lost?
Lithium primary battery
Also called a lithium battery. It can be discharged continuously or intermittently. Once the power is exhausted, it can no longer be used, and is widely used in electronic products such as cameras that consume less power.
The lithium primary battery has a very low self-discharge and can be stored for 3 years. It can be stored under refrigerated conditions and the effect will be better. It is a good idea to store the lithium primary battery in a low temperature place. Note: Lithium primary battery is different from lithium ion battery. Lithium primary battery can't be charged, charging is very dangerous!
2. Lithium-ion battery
Also known as secondary lithium battery. It can be stored for more than half a year at 20 ° C because of its low self-discharge rate and most of its capacity can be recovered.
The self-discharge phenomenon of lithium batteries, if the battery voltage is stored for less than 3.6V for a long time, it will cause the battery to over-discharge and damage the internal structure of the battery, reducing battery life. Therefore, the lithium battery stored for a long time should be recharged every 3 to 6 months, that is, the charging voltage is 3.8~3.9V (the optimal storage voltage of the lithium battery is about 3.85V), and the temperature should be kept at 40%-60%. It should not be full. The battery should be stored in a dry environment at 4 ° C ~ 35 ° C or moisture-proof packaging. Keep away from heat and keep out of direct sunlight.
