CHARGING METHOD INTRODUCTION

1. Lithium-ion Battery Charging Method:
When the charger detected the voltage of the Li-ion battery mounted onto the charger is less than 3.0V/cell, it will use 450mA current test charged the battery. Should the voltage of the battery can not increased to over 3.0V after 30 minutes of continuous trickle charging, the charger will consider this battery a bad one. For normal battery charging, the charger will use 3A/2A/1.5A to charge the battery and it will continuously monitor the batterys temperature / current / voltage. Once the preset quick charge time is up or the preset current value is reached, the charger will automatically reduce it charging current to 0.3A and its LED indicator will switched to FULL CHARGE state. But it will not stop slow charging until the preset 30 minutes time have lapse or the charging current is reduced to less than 100mA, then the battery is considered as fully charged and the charging is terminated.
Max. Charging Time: 2.5 hours
Voltage Error Detection: Less than 4V or higher than 26.5V
Trickle Charging: when <3.0V/cell, charging current approx 450mA
Trickle Charging Time: 30 minutes

2. NIMH Battery Charging Method:
The charger will quick charge the battery at constant maximum current and preset time, and continuously monitor the -dV/dT signal and temperature condition of the battery. Once a -dV/dT signal is detected, it will change to the slow charging for another 30 minutes. Then the charging process will stop and the battery is considered fully charged.
Max. Charging Time: 2.5 hours
Over-temperature Limit: 47.5 degree Celcius.
-dV/dT Measurement: After a negative voltage change (the smallest unit value) is detected and followed by 2 consecutive detections of no voltage increase, a -dV/dT is established. The negative value is the smallest unit value of 27mV.
