The most important tips for Lithium battery charging and discharging in use are:
1. Charge according to standard time and procedure, even if the new Lithium Battery, the first three times should also be done;
2. When the machine power is too low, it should start charging as soon as possible (don't wait for automatic shutdown);
3. There is no special way to activate a lithium battery. It will be activated naturally during normal use of the machine. If you insist on using the popular "first three 12-hour charges" activation method, it won't actually work.
