Advantages of lithium ion battery

1. The energy is relatively high, about 6-7 times that of lead-acid battery;
2. Long service life, which can reach more than 6 years. The battery with lithium ferrous phosphate as the positive pole is charged and discharged by 1C (100% DOD);
3. The rated voltage is high (the single working voltage is 3.7V or 3.2V), which is about equal to the series voltage of three nickel cadmium or nickel hydrogen rechargeable batteries, so as to form a battery power pack;
4. High power bearing capacity;
5. The self discharge rate is very low, which is one of the most outstanding advantages of the battery. Generally, it can be less than 1%/month, less than 1/20 of the nickel hydrogen battery;
6. Light weight, the weight of the same volume is about 1/6-1/5 of the lead acid product;
7. It has strong adaptability to high and low temperatures and can be used in the environment of - 20 ℃ - 60 ℃;
8. It is green and environment-friendly, free of toxic and harmful heavy metal elements and substances.
9. Production basically does not consume water, which is very beneficial for China, which is short of water.

In case of battery leakage, explosion and fire, please pay attention to the following matters::
- Do not put the battery into water or wet it;
- Do not use or store batteries near heat sources (such as fire or heater);
- Please use a lithium battery charger;
- Do not reverse the positive and negative connections;
- Do not directly connect the battery to the wall socket or vehicle cigarette lighter socket;
- Do not put the battery into fire or heat the battery;
- It is prohibited to short circuit the positive and negative terminals of the battery with wires or other metal objects, and it is prohibited to transport or store the battery with necklaces, hairpins or other metal objects;
- It is prohibited to impact, throw or subject the battery to mechanical vibration;
- It is prohibited to pierce the battery shell with nails or other sharp objects, and it is prohibited to hammer, step or squeeze the battery;
- It is prohibited to directly weld battery terminals;
- Do not disassemble the battery in any way;
- It is prohibited to charge the battery under fire or heat conditions;
- Do not put the battery into the microwave oven or pressure vessel;
- It is prohibited to use it in combination with primary batteries (such as dry batteries) or batteries of different capacities, models and varieties;
*Do not use the battery if it emits peculiar smell, heat, deformation, discoloration or any other abnormal phenomenon;
*If the battery is being used or charged, it should be immediately removed from the consumer or charger and stopped using;
*If the battery leaks or emits peculiar smell, it shall be removed from the place close to the open fire immediately;
Leakage of electrolyte may cause fire or explosion;
*If the electrolyte enters the eyes after the battery leaks, do not wipe it. Wash it with water and seek medical assistance immediately. If not handled in time, eyes will be injured;
*If the battery leaks and the electrolyte gets on the skin or clothes, immediately wash the affected area with flowing water, otherwise it may cause skin inflammation.
*If the equipment is not used for a long time, take out the battery and place it in a cool and dry place; otherwise, the battery may rust or have poor performance.
*If the battery terminals become dirty, clean them with a dry cloth before use. Otherwise, the battery will have poor contact, causing energy loss or failure to charge.
*Any matters not mentioned in this instruction shall be determined by both parties through consultation
*If the battery has been stored for more than three months, please charge the battery with 0.5C current to 3.7-3.9V.
