1. Lithium batteries that have not been used for a long time should be stored in a cool and dry place. It's best to store them in a semi-electric state. It's dangerous to store them at full power and the battery will be damaged. Storage without any power will also damage the battery. Check the battery every 3 months to see if it needs to be recharged.
2. Lithium batteries should be charged while they are in use, but it should be noted that lithium batteries cannot be over-discharged, which will cause irreversible capacity loss. Don't wait to charge the battery until there is no power at all. The best time to charge is when the power state of the battery is less than 10%.
3. Do not mix the lithium battery with metal objects to avoid metal objects touching the positive and negative poles of the battery. This could result in short circuiting, damage to the battery and even cause danger.
4. Use a regular compatible lithium battery charger to charge the battery. Do not use a charger with inferior quality or other types of lead-acid battery chargers to charge the lithium battery.
