    Detailed introduction

    >; Performance characteristics

    1) Good safety performance: no electrolyte leakage, no battery expansion and rupture under normal use.
    2) Good discharge performance: the discharge voltage is stable, the discharge platform is gentle.
    3) Good shockproof: the battery in the fully charged state is completely fixed, vibrates at an amplitude of 4mm, a frequency of 16.7 Hz for 1 hour, no leakage, no battery expansion and rupture, and the open-circuit voltage is normal.
    4) Good impact resistance: fully charged batteries naturally fall from a height of 20cm to 1cm thick hardwood 3 times. No leakage, no battery expansion and rupture, normal open circuit voltage.
    5) Good over discharge resistance: 25 degrees Celsius, fully recharged battery for a fixed resistance discharge for 3 weeks(resistance value equivalent to the resistance required by the battery 1 CA discharge), recovery capacity of more than 75 %.
    6) Good overchargeability: 25 degrees Celsius, fully charged battery 0.1 CA for 48 hours, no leakage, no battery expansion and rupture, normal open-circuit voltage, capacity maintenance rate of more than 95 %.
    7) Good large current resistance: fully charged battery 2 CA discharge 5 minutes or 10 CA discharge 5 seconds. No conductive parts melt, no appearance deformation.
