Why Doesn't the New Battery Turn Green After 12 Hours of Charging?
2 Answers
The reasons for not turning green are as follows: 1. Insufficient current: The charger's current is too small, resulting in a longer charging time and the inability to fully charge the battery within the expected time, causing the charger not to turn green. 2. Excessive temperature: The charging environment temperature is too high (≥45°C), preventing the battery's charging voltage from reaching the specified limit, keeping the charging current at a high level without dropping to the inflection point current, thus preventing the charger from turning green. 3. Mismatched parameters: The charger's parameter settings do not match the battery, leading to prolonged overcharging or undercharging, ultimately causing water loss in the battery and the charger not turning green. [Overcharging directly causes water loss; undercharging leads to water loss via "thermal runaway" after salination.] 4. Excessive acid content: Too much acid inside the battery obstructs the internal oxygen cycle, triggering "thermal runaway" and preventing the charger from turning green.
Hey, I just dealt with a similar issue recently, so I'll get straight to the point. If your new battery doesn't turn green after 12 hours of charging, it's likely due to a faulty charger or incorrect settings. Some chargers only switch to green when the battery voltage precisely hits 14 volts, but new batteries often come with high initial charge and may not trigger the green light. It could also be a loose charging connection or dust and debris causing poor contact. Additionally, low ambient temperatures can slow down charging, delaying the green light. My advice is not to wait endlessly—stop charging and test the battery voltage first: a fully charged battery should read above 12.6 volts. If the voltage is normal, try a different charger; if it's abnormal, take the battery to a shop for repair. Safety first—avoid overcharging, as damaging components isn't worth it.
