A:AnswerWhen battery is charging, all lights will blink green from left to right. as the battery begins to charge, one green will remain steady (when the battery reaches 25% charged). two lights will remain steady when the battery reaches 50% charged. 3 lights will remain steady when battery reaches 75% charged and then all 4 will remain steady green once the battery is 100% charged. If this does not happen, it means the battery did not charged correctly.
