Description
Technical features:
1) NPP12V series batteries have 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 battery in the fully charged state 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: the 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 over-discharge: 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 overcharge resistance: 25 degrees Celsius, fully charged battery 0.1CA charge for 48 hours, no leakage, no battery swelling and rupture, normal open circuit voltage, capacity retention rate above 95%.
