Two-stage Method
Charging is performed according to the battery charging characteristics using two-stage method.
a)
The first stage is named as „constant current‟: a): Trickle Charge: when the battery terminal
voltage is relatively low, then the charging current is low likewise which can prevent the battery
temperature is too high. b): Quick Charge: When the battery terminal voltage is relatively high,
the charging current will rise to rated value. Large current charging operation leads
to an increase in the electricity quantity of the battery.
b) The second stage is named as Float Charge: The charging current will decrease with the rising
of battery electricity. As soon as charging current value falls below 0.3A, the battery is basically
fully charged. After that charging current will only neutralize the battery self-discharge. Even
long-term charging cannot harm the battery, as charger can keep the battery fully charged and
so guarantee long lifetime of the battery.
