1, in the repair of hand drill lithium battery, need to pay special attention to safety issues. First of all, you need to use professional tools to disassemble and repair, to ensure your own safety. In addition, when disassembling the battery wireless drill battery does not charge , it is necessary to avoid damaging the protection chip and other important components inside the battery, so as not to cause harm to the battery and itself. Finally, when installing the battery, it is also necessary to pay attention to polarity to avoid problems such as short circuit or overheating of the battery.
2, secondly, check whether there is a problem with the charger, such as whether the output voltage is normal, if the charger is faulty, it can be replaced with a new one. Then, poor battery contact may also lead to failure to charge, at which time it is necessary to clean the battery contact point and ensure good contact. batteryIf the internal protection chip fails, it will affect battery charging and may need to be checked and repaired or replaced. When the battery voltage is lower than the normal value, charge to the appropriate voltage before continuing the processing.
3, or change a charger, the voltage is higher than 12 volts, and charge with a charger within 18 volts, so it is good. Do not leave the battery for a long time, which is easy to damage the battery.
4, such a failure is because the wireless drill battery is not charged Our poor contact or the line connection is not smooth when charging, timelyAfter unplugging the power supply, look at the lithium battery tail plug board whether there are some foreign objects blocked, or because the line is broken. Check the power cord for damage before use. If so, it must be wrapped with insulation tape, and do not be soaked in water and dragged carelessly during use, and do not touch heat sources and corrosive media.
5, the battery has a long-term use of self-discharge process, when the self-discharge is excessive, the battery voltage is lower than the battery charging voltage, it cannot be charged. At this time, you can first remove the battery protection board, charge for a period of time, and then use the charger to charge. Solution: Replace the charger, the voltage is higher than 12 volts, use less than 18 voltsYou can perform maintenance in the following ways: Check the battery connection. Make sure the connection between the battery and the drill is good and not loose or falling off. Check the charger. Use a multimeter to check whether the charger is working properly. If the charger shows green, the battery is fully charged. If it shows a red light, it means charging is underway. If the charger fails, it needs to be replaced or repaired.
3, when the electric drill battery does not charge, you can try the following methods to restore its charging function: ** Reactivate the battery ** : charge the battery to the full charge state, and then fully discharge, soRepeat 3-5 times to help restore battery activity.
4, check whether the battery connection joint contact is firm, such as the connection joint is not strong, tighten in time; Check whether the battery is damaged, if the battery is damaged, you can immediately replace the new battery; Check whether the battery charger is damaged. If the charger is faulty, you can go to the maintenance point for repair or replace it with a new charger.
When the battery of the electric drill cannot be charged, the following maintenance methods can be tried: Check the electricityWhether the drill has electricity, if the light is on, it means normal. If the indicator is off, check whether the power cable is properly connected and the switch is on. If the switch is on but the cable connection is faulty, reconnect the power cable. Check the spring clip on the battery, if pressed to the positive and negative terminals of the battery, it will also lead to no charge.
When the electric drill battery is not charged, you can try the following methods to restore its charging function: ** Reactivate the battery ** : Charge the battery to the full charge state, and then fully discharge it, so repeated 3-5 times, helping to restore the activity of the battery.
When the hand drill batteryWhen the battery cannot be charged, you can take the following methods to repair: Check the battery connection. Make sure the connection between the battery and the drill is good and not loose or falling off. Check the charger. Use a multimeter to check whether the charger is working properly. If the charger shows green, the battery is fully charged. If it shows a red light, it means charging is underway. If the charger fails, it needs to be replaced or repaired.
If the battery cannot be repaired after the above steps, then the battery needs to be replaced. When selecting the battery, it is necessary to match the parameters such as the model, current, and voltage of the electric drillTo ensure the normal use of the battery. When repairing the lithium battery of the electric drill, special attention needs to be paid to safety issues. First of all, you need to use professional tools to disassemble and repair, to ensure your own safety.

When the electric drill battery can not be charged, you can try the following maintenance methods: Check whether the electric drill has electricity, if the electric drill lights up, it means normal. If the indicator is off, check whether the power cable is properly connected and the switch is on. If the switch is on but the cable connection is faulty, reconnect the power cable. Check the spring clip on the battery, if pressed to the positive and negative terminals of the battery, it will also lead to no charge.
When the battery of the electric drill cannot be charged, the following methods can be taken for maintenance: Check the battery connection. Make sure the connection between the battery and the drill is good and not loose or falling off.Check the charger. Use a multimeter to check whether the charger is working properly. If the charger shows green, the battery is fully charged. If it shows a red light, it means charging is underway. If the charger fails, it needs to be replaced or repaired.
