& 4V4.5AH Lead acid battery / Emergency battery/Rechrgeable battery Characteristics:

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 16.7HZ 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 maintian normal open circuit voltage and be without leakage or batteries swelling or cracking after droping three times from 20cm height naturally to a 1 cm-thick hardwood board.

5. Good resistance to overdischarge: In temperature of 25 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 75%.
