¡El ROCKET Battery es de alta calidad!1. Good safety performance: no electrolyte leakage 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, GEL: the general life is 8-15 years, the temperature is suitable for -25 degrees to 60 degrees, the price is higher than AGM, the high current is general, the floating charge is the best, Vibrate for 1 hour with an amplitude of 4mm and a frequency of 16.7HZ, no leakage, no battery expansion and rupture. If you want to extend the use time, you should increase the temperature in winter or before entering the freezer. ¡El open circuit voltage is normal. 4. Good impact resistance: ¡El battery in the fully charged state naturally falls from a height of 20CM to a hardboard with a thickness of 1CM for 3 times without leakage, without battery expansion 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 is only equivalent to the resistance required by the battery's 1CA discharge), and the recovery capacity is above 75%. 6. Good charging resistance: 25 degrees Celsius, fully charged battery 0.1CA charge for 48 hours, no leakage, no battery expansion and rupture, normal open circuit voltage, capacity maintenance rate above 95%. 7. Good resistance to high current: the fully charged battery discharges 2CA for 5 minutes or 10CA for 5 seconds. No conductive part is blown, no appearance deformation
