There are various sayings about battery maintenance on the Internet, such as "full discharge once a month to calibrate the battery" and "avoid charging while using". But are these suggestions really scientific? Do modern batteries still need to be "calibrated" regularly? This article will reveal the truth for you.

In this era surrounded by electronic devices, batteries are the energy core of devices, and their maintenance is important. However, different devices have different battery types, usage scenarios, and frequencies, and the battery maintenance methods are also different. Today, let's take a deep look at the differences in battery maintenance for common electronic devices.

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.

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.

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.
