Advantages of removable batteries: Cost Effective : Instead of replacing the entire device, users can purchase additional batteries if the battery runs out. Emergency Replacement : In case of no power supply, the user can quickly replace the battery to continue using the device. Maintenance and Repair : If the battery is damaged, users can replace the battery individually instead of the entire device. Compatibility : Users can purchase batteries of different capacities or types to sui…

Lithium batteries are not safe. Lithium batteries will also have a chance of explosion, but the odds will not be so high, it can also be said that all batteries are not safe, there is a risk, and according to information, lithium batteries, although the chance of explosion is very small, but lithium batteries have a higher risk of spontaneous combustion. In fact, excellent regular high-quality lithium battery brands, in every aspect of lithium battery production have done their homewo…

The range of electric cars has always been a concern, because with the development of electric cars, the capacity of electric car batteries is getting bigger and bigger, there are motors that are more and more powerful, and some people need to run long distances using electric cars. When you buy an electric car, the business will often say that the electric car can run 100 kilometers, but in the actual process of riding, found that the range of the electric car is discounted, some eve…

Touch screen pen modeled after the human body contact screen, when the finger touch in the electronic screen, the human body electric field and touch screen surface formed a capacitance, the finger can suck away a small current. Touch screen pen is also this way, capacitance is a direct conductor, the current can flow from the four corners of the screen electrodes, the current flowing through these four electrodes and the distance between the tip of the pen can be realized by a precis…

The following is a detailed introduction for you. First, check the charger First of all, you need to check whether the charger is working properly. You can try to use other chargers to…

Lithium battery is a common rechargeable battery, which has the advantages of high energy density, low self-discharge and no memory effect. However, lithium batteries also have some shortcomings, such as easy to overcharge and overdischarge, affected by temperature, aging and so on. So, if you encounter a 12v lithium battery can not be charged how to repair? Here are some common lithium battery repair methods. First, 12v lithium batteries do not charge into the cause 1. Charger failur…

1, fuse tube blown: carefully check the circuit board above the various components, look at the appearance of these components is not burnt or electrolyte overflow, smell – smell there is no peculiar smell; and then measure the resistance value of the power input to see the phenomenon of a local short-circuit; and then measure the power supply filter capacitors can be normal charging and discharging, switching power tubes whether the breakdown of the damage, the UC3842 and the s…

The following collation of basic battery fault handling methods, for your reference. First, the voltage class failure 1、High battery voltage: After fully charged and static, the voltage of single string or several strings of battery is obviously high, while other monomer is normal. Failure causes: ① collection error; ② LMU equalization function is poor or invalid; ③ cell capacity is low, the voltage rises faster when charging. Failure causes Treatment: ① The voltage display value of …
