Does the charger continue charging after turning green?

The charger will continue with a 2-hour trickle float charge after turning green. Here is an introduction to the charger's charging modes: 1. Constant current with voltage limit: Charges the battery at a fixed current. Before charging, the voltage does not reach the rated voltage, so the charger shows a red light. When fully charged and the voltage reaches the rated voltage, it turns green. 2. Constant voltage with current limit: Charges the battery at a fixed voltage. If charging at a constant voltage continues, the high current can cause the battery to overheat, boil the electrolyte, and trigger intense internal chemical reactions, posing a risk of explosion. 3. Trickle float charge: This is a maintenance charge, commonly known as float charging. At the start of charging, the power is at its maximum. After several hours, the power gradually decreases, and the charging ends with 2-3 hours of low power.
When I see the charger turn green, it usually indicates the battery is fully charged, but sometimes it still trickle charges a little to compensate for natural battery discharge. Most smart chargers are designed safely—once the green light comes on, the main charging stops and won't pump in significant current to avoid overcharging, which could damage the battery or shorten its lifespan. For example, the EV charging station I use reduces power to a very low level after the green light, around just 1-2%, so there's no need to worry at all. However, this depends on the charger model—some older or cheaper versions might not stop, so it's best to check the manual. When charging, I usually disconnect promptly after the green light to protect the battery and be more eco-friendly.
