Storage, maintenance, and safety protection specifications for lithium batteries
1. Short term storage:
Lithium batteries should not be used for short periods of time (such as within 6 months). When charging the battery, it should be stored in a dry, non corrosive gas environment with a temperature and humidity between -20 ° C~35 ° C~65+20%. Temperatures and humidity above or below this range can cause metal parts to rust or batteries to leak. 2. Long term storage:
When lithium batteries are not used for a long time (such as 6 months or more), they should be charged to 50%~70% of their capacity and removed from the instrument, stored in a dry and cool environment. Batteries should be charged every 3 months to avoid prolonged storage time, which may result in irreversible capacity loss due to low battery capacity caused by self discharge. 2. The self discharge of lithium batteries is affected by environmental temperature and humidity. High temperature and humidity can accelerate the self discharge of batteries. It is recommended to store the battery in a dry environment between 10 ℃ and 25 ℃. 65+20%.
3. Charging and Charging Control:
Charging method: ①) The battery manufacturer provides a dedicated battery device; (2) Customers or users charge their instruments by installing batteries in the equipment.
Usually, lithium batteries have relatively complete protection functions (with protective plates) and do not have many other requirements for battery charging. However, in order to prevent safety issues caused by the failure of the overcharge protection function of the protective board, it is not recommended to charge for a long time. After the battery is fully charged, it should be removed. In addition, the original or battery charger must be used when charging, and the operation and use must be carried out according to the instructions, otherwise the battery may be damaged or even dangerous
4. It is strictly prohibited to dismantle or squeeze the battery without authorization, otherwise it may cause short circuit, explosion or fire.
