1. Excellent safety performance: No electrolyte leakage, battery swelling and cracking under normal use.

2. Good discharging performance: with smooth discharging voltage and mild discharging platform.

3. Good shock-proof performance: The fully charged and completely fixed battery, with 4mm amplitude and *6.7Hz frequency do Have a normal open circuit voltage without leakage, batteries swelling or cracking problem after one-hour vibration.

4. Good impact-proof performance: The fully charged battery is proved to maintain normal open circuit voltage and be without Leakage or batteries swelling or cracking after droping three times from *0cm height naturally to a+ 1 cm thick hardwood board.

5. Good resistance to overdischarge: In temperature of *5 degrees Celsius, the fully charged battery discharges with fixed Resistance which is equivalent to the one required by 1 CA discharge of the battery for three weeks, and it can restore Capacity over *5%.

6. Good resistance to overcharge: The fully charged battery is proved to maintain normal open circuit voltage and be without Leakage or batteries swelling or cracking in temperature of *5 degrees Celsius after charging at 0.1 CA for *8 hours, and the Capacity maintain over *5%.

7. Good resistance to high current: The fully charged battery is proved to be without conductive part melted or any appearance Deformation after discharging at 2 CA for 5 minutes or *0 CA for 5 seconds.
