In the cold winter, the battery level of mobile phones drops "cliff-like", and in the hot summer, the charging speed of electric vehicles slows down inexplicably - temperature is the culprit behind the scenes. Lithium batteries are as sensitive to temperature as human skin. In severe cold and heat, they may "strike" or "self-destruct". This article will dismantle how temperature destroys batteries at the molecular level and provide scientific response strategies.

"Battery repair artifact", "One move to restore 100% capacity", "Old battery refurbished as new" - similar advertisements are flooding the Internet, attracting countless users who are troubled by battery life issues. But can batteries really "rejuvenate"? Repair or IQ tax? Is refurbishment legal? This article will clear the fog for you and provide rational solutions based on battery chemistry principles and industry truths.

Lithium batteries in medical devices are the "invisible guardians" that maintain life - pacemakers rely on them to keep beating, portable ventilators rely on them to maintain oxygen supply, and insulin pumps use them to accurately control the amount of medicine. However, the maintenance of these batteries is far more complicated than that of mobile phones or laptops, and the slightest carelessness may endanger the patient's life. This article will deeply analyze the particularity of lithium batteries in medical devices and provide scientific maintenance methods to help patients and medical staff extend the life of the equipment and ensure safety.

Battery health is a key indicator of battery performance, which directly affects the battery life and service life of the device. Whether it is a mobile phone, laptop or electric car, learning to check the battery health can help you find problems in time and avoid the embarrassment of sudden power outages. This article will introduce the battery health detection methods of different devices in detail and provide tips to extend battery life.

Whether it is a spare battery for a mobile phone, an idle battery for an electric car in winter, or a dry battery stored at home, improper long-term storage will cause the battery performance to deteriorate or even become scrapped. According to statistics, about 30% of battery damage is caused by incorrect storage methods (data source: Battery University). This article will provide scientific storage methods based on the different characteristics of lithium batteries, nickel-metal hydride batteries, and dry batteries to help you keep your batteries healthy to the maximum extent.
