一：By charging time

Now the rechargeable hand drill has many clock specifications, the lithium battery used also has a variety of different voltages. Electric drills are equipped with chargers, different brands of electric clocks according to the manufacturer’s design requirements, respectively 30 minutes of fast charging, 40 minutes of fast charging, 45 minutes of fast charging, there are 1 hour standard charging, 1.5 hours standard charging and 2 hours of slow charging.

二：How to extend the battery life of rechargeable electric drill

In order to make the battery life of the rechargeable electric drill longer.

Regular charge and discharge of the battery, that is, fully charged and then discharged, and then charged to more than 70% of the electricity, the general voltage is about 3.85V, in this state of storage is ideal, pay attention to the environment, can not be wet and avoid heat.

Charge and discharge is mainly because a long time will not lead to the death of battery active substances, the capacity of the battery every month will have a certain attenuation, generally about 2%.
