■ Warnings

1. Failure to observe the following precautions may result in battery leakage, explosion or fire.

- Do not immerse the battery in water or allow it to get wet.

- Do not use or store the battery near sources of heat such as a fire or heater.

- Do not reverse the positive (+) and negative (-) terminals.

- Do not connect the battery directly to wall outlets or car cigarette-lighter sockets.

- Do not put the battery into a fire or apply direct heat to it.

- Do not short-circuit the battery by connecting wires or other metal objects to the positive (+) and negative (-) terminals.

- Do not place the battery in a microwave oven or pressurized container.

- Do not use the battery in combination with primary batteries (such as alkaline batteries) or batteries of different capacity, type or brand.

- Do not use the battery if it gives off an odor, generates heat, becomes discolored or deformed, or appears abnormal in any way.

If the battery is in use or being recharged, remove it from the device or charger immediately and discontinue use.

- Do not pierce the battery casing with a nail or other sharp object, break it open with a hammer, or step on it.

- Do not attempt to disassemble the battery in any way.

- Keep the batteries out of the reach of children. If a child somehow swallows a battery, seek medical attention immediately.

- If the battery leaks and electrolyte gets in your eyes, do not rub them. rinse them with clean running water and immediately seek medical attention.

If left as is, electrolyte can cause eye injury.

- The isolated measures are needed between battery (the bare Al layer at side and top sealing) and the PCB, and also between battery and electric equipment,

especially avoid the Al layer in packing foil contact to cathode or anode (including electric equipment), otherwise this can cause battery leakage or swelling.
