During long-term storage of the battery, it will automatically initiate self-discharging to approximately 65% in order to ensure storage safety and prolong battery lifespan. It is normal for the battery to generate slight warmth during this process.
Here are several steps and considerations to take if you notice that a battery is getting very hot:
Immediate Action:
Remove the battery from any charging source immediately if it is connected.
Place the battery in a safe, cool, and well-ventilated area away from flammable materials.
Inspection:
Check for visible damage: Look for signs of swelling, leakage, or physical damage to the battery casing.
Monitor the temperature: Allow the battery to cool down naturally at room temperature.
Long-term Storage:
Avoid high temperatures: Ensure that the storage area is within the recommended temperature range (typically between 15°C and 25°C).
Proper ventilation: Store the battery in a well-ventilated area to dissipate any heat generated during the self-discharging process.
Battery Health:
Regular checks: Periodically inspect stored batteries for any signs of overheating or damage.
Use appropriate storage modes: Some smart batteries have storage modes or settings that help maintain optimal charge levels and health.
Professional Assessment:
If the battery continues to get hot or shows signs of damage, contact the manufacturer or a professional service for further assessment. It may be necessary to replace the battery to avoid potential risks.
The generation of heat during self-discharging is usually normal and minimal, but excessive heat could be a sign of an underlying issue that needs attention. Always prioritize safety when handling lithium-ion batteries, as they can pose risks if not managed properly.
