Battery advantages:
1. Good performance: no electrolyte leakage, no battery expansion or rupture under normal use.

2. Good discharge performance: stable discharge voltage and flat discharge platform.

3. Good vibration resistance: The fully charged battery is completely fixed and vibrates at an amplitude of 4mm and a frequency of 16.7Hz for 1 hour. There is no leakage, no battery expansion or rupture, and the open circuit voltage is normal.

4. Good impact resistance: a fully charged battery can naturally fall from a height of 20cm to a hard board with a thickness of 1cm three times. There is no leakage, the battery does not swell or rupture, and the open circuit voltage is normal.

5. Good over-discharge resistance: at 25 degrees Celsius, the battery in a fully charged state can be discharged with constant resistance for 3 weeks (the resistance value is equivalent to the internal resistance required for 1CA discharge of the battery), and the recovery capacity is above 75.

6. Good overcharge resistance: at 25 degrees Celsius, a fully charged battery can be charged at 0.1CA for 48 hours without leakage or battery expansion or rupture. The open circuit voltage is normal and the capacity maintenance rate is above 95.

7. Good resistance to high current: a fully charged battery is discharged at 2CA for 5 minutes or 10CA for 5 seconds. No conductive parts are burned out and there is no appearance deformation.
