Lithium iron phosphate battery has been widely used by consumers by virtue of its advantages of "energy conservation and environmental protection". If you don't pay attention to some matters in the work and use of lithium iron phosphate battery, it will bring great losses to consumers. Let's introduce the precautions for the use of lithium iron phosphate battery?
1. Lithium iron phosphate battery can be stored in a clean, dry and ventilated room with ambient temperature of - 5 ℃ - 35 ℃ and relative humidity of no more than 75%. It shall avoid contact with corrosive substances and away from fire source and heat source. The battery capacity is maintained at 30% to 50% of the nominal capacity. It is recommended to charge the stored battery every 6 months;
2. Lithium iron phosphate battery should not be stored at full power for a long time. It is easy to produce air expansion after long-term storage, which will affect the discharge performance. The best storage voltage is about 3.8V for a single chip. It can be filled before use, which can effectively avoid air expansion of lithium iron phosphate battery.
3. Lithium iron phosphate battery is different from nickel chromium and nickel hydrogen batteries because it has a very bad "aging" characteristic, that is, after storage for a period of time, even if it is not recycled, part of its capacity will be permanently lost. Lithium iron phosphate battery should be fully charged and then stored to reduce capacity loss. The "aging" speed is different at different temperatures and different power states;
4. Due to the service characteristics of lithium iron phosphate battery, lithium iron phosphate battery supports high current charging and discharging. The storage time of lithium iron phosphate battery after being fully charged shall not exceed 72 hours. It is recommended that the user be fully charged the day before preparation for operation;
5. Unused batteries shall be stored in the original packaging away from metal objects. If the package is opened, do not mix the batteries together. The unpacked battery is easy to mix with metal objects, resulting in short circuit of the battery, resulting in leakage, discharge, explosion, fire and personal injury. One way to prevent this is to store lithium iron phosphate batteries in their original packaging.
The above is what we need to pay attention to in the process of using lithium iron phosphate battery. Paying attention to the above can effectively prolong the service life of lithium iron phosphate battery.
