Is lithium iron phosphate battery suitable for storage at low temperatures?

The usage environment of ordinary lithium iron phosphate batteries: the charging temperature of lithium batteries is 0-45 ℃, and the discharge temperature of lithium batteries is -20 ℃~60 ℃. The self discharge of lithium batteries is affected by environmental temperature and humidity. High temperature and humidity can accelerate the self discharge of batteries. It is recommended to store the batteries in a dry environment between 0 ℃ and 20 ℃.

Is lithium iron phosphate battery suitable for storage at low temperatures?

Lithium batteries need to be fully charged before storage. Lithium iron phosphate batteries can be stored for more than half a year at 20 ℃, indicating that they are suitable for storage at low temperatures. Someone once suggested storing the rechargeable battery in the refrigerator compartment, which is indeed a good idea. Lithium primary batteries have low self discharge and can be stored for up to 3 years. Storing them under refrigerated conditions will result in better performance. Storing lithium primary batteries in a low-temperature place is a good method.

Lithium batteries exhibit self discharge phenomenon, and long-term storage can lead to over discharge and damage to the internal structure of the battery, reducing its lifespan. Therefore, lithium-ion batteries that have been stored for a long time should be recharged every 3-6 months, and it is advisable to charge them to a voltage of 3.8-3.9V.

The higher the storage temperature and the more fully the battery is charged, the more severe the capacity loss. So it is not recommended to store lithium-ion batteries for a long time. If users have idle batteries in their hands, experts recommend storage conditions such as a charging level of 40% and a storage temperature below 15 degrees Celsius or lower. The application temperature range of lithium iron phosphate batteries is very wide. They can still be used outdoors in winter in the north, but their capacity will decrease significantly. If they return to room temperature, their capacity can be restored.

How to store lithium iron phosphate batteries?

Lithium iron phosphate batteries do not have memory effects and can be charged as needed. However, it should be noted that lithium batteries cannot be over discharged, as over discharge can cause irreversible capacity loss. When the machine reminds that the battery is low, it should start charging immediately.

In daily use, freshly charged lithium iron phosphate batteries should be left unused for half an hour until their charging performance is stable, otherwise it will affect the battery's performance.

When not using the instrument, be sure to remove the battery and store it in a dry and cool place.

Pay attention to the usage environment of lithium iron phosphate batteries: the charging temperature of lithium batteries is between 0 ℃ and 45 ℃, and the discharge temperature of lithium batteries is between -20 ℃ and 60 ℃.

Do not mix the battery with metal objects to prevent them from touching the positive and negative poles of the battery, causing a short circuit, damaging the battery, and even posing a danger.

Do not tap, puncture, step on, modify, or expose the battery to sunlight. Do not place the battery in microwave, high-voltage, or other environments.

Use a legitimate matching lithium battery charger to charge the battery, and do not use inferior or other types of battery chargers to charge lithium iron phosphate batteries.

Lithium batteries should be charged with 50% to 80% of their battery capacity when not in use for a long time. They should be removed from the instrument and stored in a dry and cool environment. The battery should be charged every 3 months to avoid prolonged storage and irreversible capacity loss caused by self discharge.

The self discharge of lithium iron phosphate batteries is affected by environmental temperature and humidity. High temperature and humidity can accelerate the self discharge of the battery. It is recommended to store the battery in a dry environment between 0 ℃ and 20 ℃.

In what state is lithium iron phosphate battery best preserved?

Lithium iron phosphate batteries have a storage temperature of 40% at 0 degrees Celsius and a charging state of 98%;

Lithium iron phosphate batteries have a storage temperature of 25 degrees Celsius at 40% and a charging state of 96%;

Lithium iron phosphate batteries have a storage temperature of 40 degrees Celsius and a charging state of 85%;

Lithium iron phosphate batteries have a storage temperature of 60 degrees Celsius at 40% and a charging state of 75%;

Lithium iron phosphate batteries have a storage temperature of 0 degrees Celsius at 100% and a charging state of 94%;

Lithium iron phosphate batteries have a storage temperature of 25 degrees Celsius at 100% and a charging state of 80%;

Lithium iron phosphate batteries have a storage temperature of 40 degrees Celsius at 100% and a charging state of 65%;

Lithium iron phosphate batteries have a storage temperature of 60 degrees Celsius at 100% and a charging state of 60%.

At present, lithium iron phosphate batteries are recognized as a green energy source by the country and are favored by many consumers. They mainly have advantages such as small size, large capacity, high single cell voltage, low self discharge rate, multiple battery cycles, and no pollution. It is best to take out and use the lithium batteries once a month to ensure their good storage status and prevent complete loss of battery power and damage to the batteries.
