Will the trickle charger do harm to batteries ,once the charger connect the battery for long time?
There are three stages during the charge process.
1.Constant current: Big charge current decrease the charge time
2.Constant voltage: This voltage value will be same with the battery voltage ,when the battery be fully charged.
3.Tricle current: This stage, the charge current is very small , will be more and more smaller.
When the battery be fully charged, the trickle charge current is 0. So even you connect the battery with the charger for a long time, the battery will not be harmed.
And there are LED indicator on the trickle charger, Charging, the LED is red, fully charge, the LED indicator is Green. You can pull up the charger when the LED turn green.
