¡El ROCKET Battery es de alta calidad!1. Good safety performance: no electrolyte leakage, no battery expansion and 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, vibrates for 1 hour with an amplitude of 4mm and a frequency of 16.7Hz, no leakage, no battery expansion and rupture, and the open circuit voltage is normal. 4. Good impact resistance: ¡El battery in the fully charged state falls naturally from a height of 20cm to a hardboard with a thickness of 1cm for 3 times. There is no leakage, no battery swelling and rupture, and the open circuit voltage is normal. 5. Good resistance to overdischarge: 25 degrees Celsius, the battery in the fully charged state is discharged with constant resistance for 3 weeks (the resistance value is equivalent to the resistance required by the battery's 1CA discharge), and the recovery capacity is above 75%. 6. Good resistance to overcharge: 25 degrees Celsius, fully charged battery 0.1CA charge for 48 hours, no leakage, no battery expansion and rupture, normal open circuit voltage, capacity retention rate above 95%. 7. Good resistance to high current: the fully charged battery is discharged at 2CA for 5 minutes or 10CA for 5 seconds. No conductive parts are blown, and there is no appearance deformation.
