Read the following matters carefully to ensure the correct use of lithium ion batteries.

18650 and 16340 and 14500 batteries are strictly prohibited. If the battery voltage is lower than 2.75V, it is forbidden to turn on the flashlight. It must be charged. Otherwise, it will seriously affect the battery life. If the new battery is used for the first time, the battery voltage will be placed in the "0V" battery, and it will be scrapped immediately.

So when the brightness of the flashlight drops, it should be charged immediately, so as to prevent the battery from being discharged and causing the damage to the internal short circuit of the battery.

In order to prevent battery leakage, explosion, fire and other cases, please pay attention to the following matters:

Do not put the battery into the water or wet it.

- do not use or store batteries near heat sources (such as fire or heater);

- please use the original charger;

- do not reverse the positive and negative;

Do not connect the battery directly to the wall socket or on the vehicular cigarette - type socket.

Do not put the battery into the fire or heat the battery.

It is forbidden to short-circuit batteries by wires or other metal objects. It is forbidden to transport or store batteries with necklaces, hairpins or other metal objects. The actual capacity is 2200 ma.

- no impact, throwing, or mechanical vibration of the battery;

- prohibit the use of nails or other sharp objects to pierce the shell of the battery, and prohibit the hammer or foot battery.

- no direct welding of battery terminals;

- it is forbidden to decompose the battery in any way.

Forbidden to charge the battery in fire or extreme conditions.

- the battery is forbidden to be placed in a microwave or pressure vessel.

- prohibit the use of a battery (such as a battery) or a combination of different capacities, models and varieties of batteries.

- if the battery is smelling, heating, deforming, discoloring, or having any other abnormal phenomena, if the battery is being used or charged, the battery should be used or charged.

Remove from the appliance or charger immediately and stop using it.

- the battery should be placed in a place where the child is not in contact. If the child is not careful to swallow the battery, it should seek medical assistance immediately.

If the battery is leaking or having a peculiar smell, it should be removed from the open fire immediately.

The leakage of electrolyte may cause fire or explosion.

If the electrolyte leaks into the eye, do not wipe it, wash it with water, and seek medical assistance immediately. If you don't handle it in time, your eyes will be hurt.

Do not use the battery in the thermal environment, such as direct sunlight or heat of the car. Otherwise, the battery will overheat and may be ignited.

It will affect the performance of the battery and shorten the service life of the battery.

Batteries can only be used under the following conditions, otherwise the performance of the battery will be reduced or the life of the battery will be shortened. The use of batteries outside this temperature range may be possible

Cause to overheat, explode, or fire.

Working environment:

Charging: 0 C ~45 C

Discharge: -20 C ~60 C

Storage for 30 days: -20 C ~45 C

Storage for 90 days: -20 C ~35 C

When a child uses a battery, it needs to be taught in accordance with the content of the user's instructions, and pay close attention to them to ensure the right use of the battery.

If the battery leaks and the electrolyte gets on the skin or clothes, rinse the affected area with liquid water immediately, otherwise it may cause inflammation of the skin.

Read the battery's installation instructions and correctly install and disassemble the battery.

If the equipment is not used for a long time, remove the battery and place it in a cool, dry place, otherwise the battery may rust or poor performance.

If the terminal of the battery becomes dirty, clean it with dry cloth before use. Otherwise the battery will be in bad contact, which causes energy loss or can not be recharged.
