Precautions and instructions for using polymer lithium batteries.
To ensure proper use of lithium batteries, please read the user manual before use.
1. Warning:
a. Do not place lithium batteries in fire.
b. Do not reverse the polarity of the lithium battery charger.
c. Do not short-circuit lithium batteries (P+, P -).
d. Avoid excessive impact and vibration of lithium batteries.
e. Polymer lithium batteries cannot be disassembled or twisted.
f. The battery cannot be immersed in water.
g. Polymer lithium batteries should not be mixed with other types and models of batteries.
h. Please keep out of reach of children.
2. Polymer lithium battery charging:
a. Please use a suitable charger to charge the battery.
b. Do not charge with a repaired or damaged charger.
c. Do not charge lithium batteries for more than 24 hours.
d. Do not use a charging current exceeding the maximum specified in the specification sheet to charge polymer lithium batteries.
e. Charging voltage: Please do not exceed the maximum charging voltage specified in this specification.
f. Charging temperature: The battery needs to be charged and discharged within the specified temperature range.
g. Please use constant current and constant voltage method for charging. Do not reverse the positive and negative poles to avoid damaging the battery.
h. Polymer lithium batteries must be stored with electricity and charged and discharged every three months.
3. Discharge of polymer lithium batteries:
a. The discharge current shall not exceed the maximum rated discharge current specified in the specifications. High current can cause lithium batteries to generate heat and reduce capacity.
b. Discharge temperature: The battery must be discharged within the temperature range specified in the specifications.
c. Overdischarge: The battery will not be damaged if it is instantly discharged and then charged immediately. But if left for a long time, the polymer lithium battery will be damaged. During long-term storage, the battery may become over discharged due to self discharge. Therefore, to avoid over discharge of lithium batteries, they must be stored with electricity.
4. Precautions for flexible packaging of polymer lithium battery aluminum foil:
a. Do not hit the battery with sharp points.
b. Trim your nails or wear gloves.
c. Clean the workbench to avoid sharp parts.
d. Heating the edge to over 100 ° C and bending the edge can easily damage the edge.
5. Precautions for Operating Polymer Lithium Battery Ears
The mechanical strength of polymer lithium battery lugs is not exceptionally strong, especially aluminum lugs. Do not bend the ears unless necessary. Extreme ear connection, it is recommended to use ultrasonic or spot welding methods; The shell design should ensure that the pole piece is not subjected to external forces. If manual welding of protective plates is used, the following precautions are crucial for ensuring battery performance:
a. The temperature for welding chromium iron must be controllable and anti-static;
b. The temperature of chromium iron during welding should not exceed 370 ℃;
c. The soldering time cannot exceed 3 seconds;
d. The soldering frequency cannot exceed 5 times, and the next soldering can only be carried out after the electrode has cooled down;
e. It is strictly prohibited to directly heat the battery cells, as temperatures above 100 ℃ can damage the cells.
