 Precautions and prohibitions:

- Do not put the battery in fire or heat;

- Do not disassemble the battery;

- It is strictly forbidden to immerse the battery in water. When not in use, it should be placed in a cool and dry environment;

- It is forbidden to use the battery near hot and high temperature sources, such as fire, heater, etc.;

- When charging, use a special charger for lithium-ion batteries;

- It is strictly forbidden to reverse/directly connect the positive and negative poles to use the battery;

- It is strictly forbidden to insert the battery directly into the socket;

- It is forbidden to use metal to directly connect the positive and negative electrodes of the battery to short circuit;

- It is forbidden to transport or store batteries together with metals, such as hairpins, necklaces, etc.;

- It is forbidden to hit or throw, step on the battery, etc.;

- Direct welding of the battery and piercing the battery with nails or other sharp objects is prohibited;

- Do not use or place the battery in high temperatures (in the sun or in a very hot car), otherwise it may cause the battery to overheat, catch fire or malfunction and shorten its lifespan;

- Do not use in places with strong static electricity and strong magnetic fields, otherwise it will easily damage the battery protection device.

- If the battery leaks and the electrolyte gets into your eyes, rub your eyes, rinse your eyes with clean water and seek medical treatment immediately;

- If the battery emits odor, heat, discoloration, deformation, or any abnormality during use, storage, or charging, immediately remove the battery from the device or charger and discontinue use;

- Discarded batteries must be covered with insulating paper to prevent fire and explosion;

- If the battery terminal is dirty, wipe it with a dry cloth before use, otherwise it may cause poor contact and failure or overheating.

WARNINGS: The product is NOT subject to the right of return within 14 days (except for non-conformities upon delivery).

In order to avoid certain risks and comply with international sanctions on certain countries and entities, we reserve the right to select customers for this product (depending on the customer, we may request a questionnaire or end-user declaration). Thank you for your understanding.

It will be installed and used only by specialized personnel.

For safety reasons during transport, the battery is not delivered from the factory fully charged. Before use, it must be charged to 100% (use only chargers suitable for this type of battery). The battery can reach its maximum capacity after a minimum of 8 charge-discharge cycles.

Warnings: Do not throw into fire, do not short-circuit, do not throw in the trash after use. Hand over used batteries only to authorized collection centers (such as waste battery collection bins in large stores).
