① Do not mix the lithium-ion battery with metal objects to prevent metal objects from touching the positive and negative poles of the lithium-ion battery, causing short circuit, damage to the lithium-ion battery and even danger.

② Grasp the correct charging method: first connect the charger and battery pack, and then connect the charger power plug to the 220V AC power supply. This connection sequence can prevent electric sparks when plugging and unplugging the charging plug. The charger displays a red indicator when the power is turned on.

③ The lithium ion battery can enter the dormant state under the cold storage condition. However, after the lithium bicycle is used under high temperature, the removed battery pack cannot be placed in the freezer immediately, but placed in a cool place to slowly cool the lithium ion battery.

④ In the daily use of lithium-ion batteries, they should be put aside for about half an hour after being charged, and then used after the battery performance is stable. Give the lithium ion battery a standing period, otherwise it may affect the normal performance of the battery.

⑤ Please stop using the lithium-ion battery when it is found to have discoloration, deformation or unusual phenomena. During actual charging, stop charging when the specified charging time is exceeded and the charging work cannot be completed, otherwise the lithium ion battery will leak, heat and damage.

⑥ Prevent the use of lithium ion batteries that are hot after being fully charged. When the battery is newly charged, the temperature may be very high. If the internal temperature of electronic components is used immediately, it will rise, which may have a negative impact on the electronic components of the device.
