The 12v battery has not been full for 24 hours, which may have the following two reasons.
1. The charger is faulty
Due to the reduced output current of the charger, 24 hours are similar to trickle charging. If the battery is not hot, it can prove that the charge is too small.
The charger may change the light function of the zombie, at this time due to overcharging bottle will heat.
2. Battery failure
Due to the short circuit of a unit plate in the 6 units, the charger can not detect the full voltage signal, the so-called has been in the state of charging.
12v battery is not full for 24 hours, there may be the following situations:
1, the battery capacity is too large, the charger power is too small, the charger 24 hours work is less than the battery capacity;
2, the battery has aging damage, although the display charging, but the voltage has not risen, so it has been charging;
3, when the charger fails, it only shows normal charging, but in fact there is no effective current and voltage.
Not being fully charged for so long means there's something wrong with the battery, which may need a refill.
