A: We recommend not putting the battery into the equipment when the battery is not used for a long time. The battery should be discharged to half charge (i.e. when the equipment displays only half its power). ), then the battery should be stored in a dry place. In a room temperature environment, you can put it in the PVC protective cover we provide for protection during storage.
B: For batteries stored for a long time, in order to maintain the battery performance at its best, please remove the battery every 3 months. Take it out and charge it again, then charge it half charged and put it away. This is what I saw on the official Punofi website. It can be seen that they are very knowledgeable about battery maintenance.
The parameters of the 32650 lithium iron phosphate battery are as follows:
1. Overall dimensions : external diameter 32 mm, height 65 mm.
2. Capacity Range: The capacity range is between 4500 and 6500 mAh, but versions above 5000 mAh are also available.
3. Voltage and charging limits: The rated voltage is 3.2 volts, and the voltage after full charge can reach 3.7 volts.
4. Charging Current: Some information mentions that the charging current is 15A, but this refers to the design value or measurement of a specific product.
5. The current under the test conditions is not the standard configuration of all 32650 lithium iron phosphate batteries.
6. Discharge cut-off voltage: Different products have different discharge cut-off voltages, such as 41.25V, 18.4V, etc.
7. Internal resistance: The internal resistance of the finished product is between 100 and 200.
8. Safety Features: It has functions such as que short circuit protection, overcharge protection, overdischarge protection, overcurrent protection and temperature protection.
9. Operating Temperature Range: The operating temperature range during charging is 0 degrees Celsius to 45 degrees Celsius, while the temperature range during discharging is minus 20 degrees Celsius to 60 degrees Celsius.
10. Storage Temperature: During storage, it should be kept between minus 20 degrees Celsius and 40 degrees Celsius.
