The Powerking 912 uses a 12 volt battery. As a 12V lithium electric drill, it adopts brushless design, quieter and more energy-saving, more powerful and smaller in size. The body can be said to be small, flexible and light, and can. be used freely in tight places. It is worth mentioning that in terms of materials, Shida also invests in craftsmanship and technology.
Premium soft rubber handle is used to reduce resistance. The vibration felt by the hand when tightening screws and drilling is also lighter than that of ordinary lithium electric drills, which can better protect the wrist.
Characteristics of lithium batteries
1 They have a higher weight-to-energy ratio and a higher volume-to-energy ratio.
2. High tension. The voltage of a single lithium battery is 3.6V, which is equal to the series voltage of three rechargeable nickel-cadmium or nickel-metal hydride batteries.
3. The battery has low self-discharge and can be stored for a long time. This is the most important advantage of this battery.
4. No memory effect. Lithium batteries do not have the so-called memory effect of nickel-cadmium batteries, so lithium batteries do not need to be discharged before being charged.
5. Long life expectancy. Under normal working conditions, the number of charge and discharge cycles of lithium batteries is far more than 500 times.
6. Can be charged quickly. Lithium batteries can generally be charged with a current of 0.5 to 1 times the capacity, shortening the charging time to 1 to 2 hours
7. They can be used in parallel as desired.
8. Since the battery does not contain metal elementsheavy such as cadmium, lead and mercury, it does not pollute the environment and is the most advanced green battery in the world.
9. High cost. Compared to other rechargeable batteries, lithium batteries are more expensive.
Yes, keeping it without power for a long time will cause damage to the battery, which is irreversible and cannot be repaired. The battery cannot be replaced.
If not charged for a long time, the battery itself will automatically discharge. If self-discharge is severe, the battery may be seriously cracked and short-circuited. So it may not be available. Lithium batteries have no memory effect and can be recharged at any time.
Lithium battery storage methods that are not suitable for long-term use:
1. If lithium batteries are not used duringant a long time, they should be charged to 50% to 80% power, removed from the instrument and stored in a dry and cool place, and recharge the battery every 3 months to avoid excessive storage time and battery too low due to self-discharge, resulting in irreversible capacity. loss.
2. Self-discharge of lithium batteries is affected by ambient temperature and humidity. High temperature and humidity will accelerate the battery's self-discharge. It is recommended to store the battery in a dry environment. 0℃ and 20℃.
