3. LED Light battery 12V 20Ah safety test

    @Testing Conditions: Ambient Temperature: 25±5℃; Huminity:45%~75%.

No. Items Standards Testing Methods
1 Short-Circuit The battery should be no remarkable breakage, distortion. And charge normally. Use a resistor with less than 0.05Ω to make the battery short circuit for 1 hour. The appearance and characteristics are normal.
2 Over Discharge Protection Test The battery should be no remarkable breakage, distortion. Appearance and charge are normal. Discharge the battery at the rate of 2A with the load of 30Ω for 24h . Charging for 10sec with specified adapter , and check the voltage(≥8.0V)
3 Impact Test The battery should be no explosion or catch fire Place a full charged battery on a flat and put a stainless steel stick (Diamond 15.8mm) in the middle of the battery upright . Beat the steel stick with 9.1Kg
