Winter battery play below 0 ° c is not good In normal mode full of can with strong filling patterns Complement more half an hour, 1 hour left and right sides Can make the battery performance is better.
One :The charger to the battery charging time is only a few minutes, or even less time, has shown the full state.
1. check whether the charger is over current, over heat protection or low voltage protection (there is inconsistent voltage), and observe whether the cooling fan works normally.
2. It indicates that the battery has no capacity or is already full (it is recommended to retest it after discharging, or select another battery without power).
3: it is recommended to try adding battery supplement or distilled water.
4: check whether the charger output clip is in good contact with the battery column.
Two: When charging the battery battery shell heat or charger working for a long time still can not show full.
1: check whether there is a short circuit in the battery, so that the charging voltage cannot reach the set voltage of the charger for a long time.
2: no more than 0.3A current exists in the battery.
3: battery production process, material is not qualified, it is recommended to use genuine battery.
4: please replace a good battery and retest.
Three: Charger charging in the normal connection when there is a buzzer alarm or does not work at all.
1: check whether the battery voltage is seriously damaged, resulting in the charger's low-voltage protection (there is an inconsistent voltage).
2: the battery is used for a long time so that the old (scrap battery) or internal resistance, battery short circuit.
3: whether there is still a buzzer alarm when the power supply is connected to the space-time load state.
4: it is recommended to replace the good battery and retest.
