However, lithium batteries should not be idle for a long time. Once the voltage is too low, it will have an impact on the life of lithium batteries.

 

2, some information that lithium ions in the first 3-5 times, charging time should be longer than 14 hours, the reason is to fully activate the activity of lithium ions. In fact, this is not based on the fact that the current lithium-ion battery does not require the customer to activate itself, so it does not have to be charged for a long time.
