2. Electrical Performance

RAYWILL Battery use nickel hydroxide for the positive electrode, hydrogen absorbing alloys in its negative electrode, and potassium hydroxide solution in its electrolyte. The electro-chemical processes are described as below:

Charging:

For standard charging , we recommend constant current charging at 0.1C rate for 14-16hours at 20°C,Overcharge at 0.1C rate without time limit is allowed. For fast charging, we recommend a charging current of 0.5C rate to 1C rate , with the mandatory implementation of quick-charge termination methods . The termination methods include:
Temperature Cut-Off(TCO) of 55°Cmaximum , Rate -of -Temperature -Rise (dT/dt) of 0.7-0.8°C/min. Negative -Delta-Voltage method with 10-15mV/cell . Timer Control can also be applied ,for a capacity input of 120% of nominal. For maximum capacity , trickle charge can be applied after quick -charge is terminated. We recommend trickle-charge of 0.1C for 2 hours, or 0.2C for 1 hour.

Charge type	Charge current	Charge time	Temperature
Standard charge	0.1 C	15 h	0-50 C
Quick charge	0.5 C	2.5 h	0-50 C
Fast charge	1.0 C	1.2 h	0-50 C
Trickle charge	1/30-1/20 C	Continuously	0-35 C

Charge characteristics

Discharging:

At 20±2°C, it can be discharged continuously at 0.2C rate to 1.0V cut-off, or quick discharged continuously at 3Crate to 0.9V.

Discharge Characteristics

Cycle Life:

500 - 1000 charge/discharge cycles can be expected under normal use with a specific charger.
