Trickle generally means that after the battery is fully charged with high current at first, the charger judges that the charging is close to full according to the detected voltage, and then continues to charge the battery by trickle charging. At this time, the charging current is quite small and intermittent, such as charging for 5 seconds and stopping for 5 seconds to fully charge the battery.

That is, the battery will turn green after being fully charged. Continue to charge with low current will make the battery more fully charged, but don't reduce the battery life because of long-term overcharge. Generally, the power can be pulled out after being fully charged for about one hour, that is, it will turn green after being fully charged. Continuing to charge with low current will make the battery more fully charged, but don't reduce the battery life because of long-term overcharge. Generally, it takes about an hour to charge with a trickle to pull out the electricity.
