It is not uncommon for lithium batteries (such as mobile phones, cameras, and drone batteries) to be accidentally soaked in seawater during outdoor activities, seaside trips, or emergencies. The high salinity and conductivity of seawater may cause serious damage to the battery and even cause safety hazards. This article will provide you with a detailed analysis of the correct handling process and scientific principles of lithium batteries soaked in seawater to help you avoid risks and reduce losses.

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.
