Power banks have long become a "life-saving artifact" for modern people to travel, but many people have misunderstandings about their use: some people are used to plugging them in as backup power, some people leave them idle for a long time after they are fully charged, and some people even treat power banks as "permanent plug-in devices." Are these behaviors really safe? Will long-term plugging in damage the power bank? This article will analyze the plug-in risks of power banks based on the principle of lithium batteries and provide a scientific maintenance guide. I. The core of power banks: the two sides of lithium batteries Power banks generally use lithium-ion batteries or lithium polymer batteries , and their characteristics determine the taboos of use: a. Fear of overcharging and over-discharging: long-term storage with full or empty power will accelerate aging. b. High temperature is an invisible killer: continuous plugging in may cause inter...

Winter is here, and many electric car owners have found that the range displayed when fully charged is "halved", the charging speed is slowed down, and even the power output is weakened. Some people say that "electric cars are naturally afraid of cold", while others question that "there are problems with the battery quality". What is the truth? This article will analyze the impact of low temperature on electric car batteries based on the chemical properties of lithium batteries, and provide a full range of solutions from charging skills to driving habits to help you say goodbye to winter range anxiety. I. Are electric car batteries really "afraid of cold"? 1. The essence of low temperature effects: reduced activity, non-permanent damage When lithium batteries are at low temperatures (especially below 0°C), the viscosity of the electrolyte increases, and the migration speed of lithium ions between the positive and negative electr...

When buying a new mobile phone, many people will hear such advice: "The first charge should be fully charged for 12 hours" and "The first three times, the battery must be fully used and then fully charged to activate the battery." These sayings have been passed down from generation to generation by the elders, and are even regarded as "maintenance secrets" by some businesses. However, these suggestions actually come from battery technology that has long been obsolete. This article will trace the origin of the saying "activate the battery", analyze the characteristics of modern lithium batteries , and provide a scientific guide to charging new mobile phones. I. The historical roots of the saying "activate the battery" 1. "Memory effect" in the era of nickel-metal hydride batteries In the era of feature phones, mobile phones generally use nickel-metal hydride batteries (NiMH) . This type of battery has an obvious ...

Many people have heard the saying that "it is better to charge the phone after it shuts down automatically". Some people think that this can "calibrate the battery", while others think that it can extend the battery life. However, this concept actually originated from the early era of nickel-metal hydride batteries and is not applicable to the lithium batteries of modern smartphones. This article will explore the characteristics of lithium batteries in depth, reveal the truth of this misunderstanding, and share scientific charging suggestions. I. Why is there a saying that "it is better to charge the phone after it shuts down"? 1. Historical background: the memory effect of nickel-metal hydride batteries In the era of nickel-metal hydride batteries (NiMH) , batteries do have a "memory effect". If the battery is charged before it is fully discharged, it will "remember" the shorter usage cycle, resulting in a decrease in cap...

With their flexibility and powerful shooting capabilities, drones have become a powerful tool for aerial photography, mapping, agriculture and other fields. However, many pilots have found that the life of drone batteries seems to be shorter than that of batteries for other devices. A brand new battery may have problems such as significantly reduced battery life, slower charging speed and even swelling after dozens of flights. What scientific principles are hidden behind this? How can we effectively extend the battery life? This article will deeply analyze the key reasons for the aging of drone batteries and provide practical maintenance guidelines. I. Why are drone batteries "short-lived"? Four core reasons 1. High-rate discharge: the "extreme sport" of batteries When drones take off, hover, and fly at high speed, the battery needs to power the motor with an extremely high current (5C~15C rate). For example: If a 5000mAh battery is discharged at a...

Understanding the calculation method of lithium battery cycle times and the influencing factors is crucial for us to correctly use and maintain lithium batteries. When using electronic devices in daily life, we should try to adopt scientific charging methods, avoid extreme temperature environments, and choose lithium battery products with reliable quality. Only in this way can we extend the service life of lithium batteries, give full play to their performance advantages, and bring more convenience to our lives and work. I. What is the "cycle times" of lithium batteries? The cycle times of lithium batteries refers to the complete process of the battery from full charge to full discharge and then full charge. For example, if a 3000mAh battery is used from 100% to 0% and then charged back to 100%, it is considered a complete cycle. However, in actual use, we rarely fully discharge the battery and then charge it again. Therefore, the calculation of the number o...

Today, electronic devices such as mobile phones and laptops have become part of our daily lives. Many people are used to plugging in their devices for a long time, but the debate about whether plugging in will damage battery life has never stopped. Some people say that "charging all the time will cause the battery to swell", while others believe that "modern technology has solved the overcharging problem". Based on the scientific principles of lithium batteries , this article will explore the impact of long-term plugging in on batteries and provide practical maintenance suggestions. I. Core characteristics of lithium batteries Modern electronic devices generally use lithium-ion batteries , which have completely different characteristics from traditional nickel-hydrogen batteries: No memory effect: No need to fully charge and discharge, charging as you use is healthier. Fear of extreme conditions: Keeping 0% or 100% power for a long time will accelerate ag...
