12 hours.
It takes about 12 hours to fully charge with a 5A charger, which is relatively slow. But if you don't mind the slow speed, it's good for the battery itself.
Proper use of lithium batteries: 1. Charge according to standard times and procedures, even for the first three times. 2. When the lithium battery displays a low battery warning while driving the electric vehicle, the lithium battery should be charged as soon as possible. 3. Activation of lithium battery electric vehicles does not require special methods. The lithium battery will be activated naturally when the electric vehicle is driving.
