The most common situation in winter is that the phone battery power is not long-lasting enough. And the colder the weather, the faster the electricity decreases. The editor reminds everyone to save some power to your phone in colder places. Otherwise, when the battery is completely depleted, the pho...

In recent years, electric bicycles have become a popular means of transportation for commuters and a beautiful scenery in people's lives. As is well known, a good electric vehicle must have a good battery to ensure its driving range. However, some numbers and letter symbols on the battery often...

Why do some lithium battery protection boards need to be activatedNot all lithium battery protection boards need to be activated now, only some protection ICs need to be activated, and this is an old IC solution. The old IC solution requires this to make the protection boards not work, reduce electr...

Due to the current chaotic and mixed market of electric vehicle batteries, some practitioners lack professional ethics and maliciously attack their peers. Some businesses even sell counterfeit batteries to deceive consumers, causing many consumers to lose confidence in the electric vehicle battery i...

The 18650 battery is cylindrical with liquid inside. Due to the design and material of the battery, it is suitable for high currents, so almost all laptops and electric vehicles use the 18650 battery design; Only super laptops can use polymer lithium batteries instead of 18650 batteries due to energ...

The battery capacity is divided by the charging current, multiplied by a coefficient of 1.2, and the time unit is in hours.Explanation: Generally, the capacity of a battery is indicated on the battery, in milliamperes. The larger the value, the greater the capacity. For example, 1200mAh means that t...

There are two basic methods for naming lithium batteries, one is based on the positive electrode material of the lithium battery, and the other is based on the size. These two basic classifications start from the common aspect and have general characteristics. In addition, there is a classification...

The service life of lead-acid batteries is related to many factors and cannot be generalized. There are the following factors that affect the service life of lead-acid batteries:1. Discharge depthThe discharge depth refers to the degree to which the discharge stops during use. 100% depth refers to t...

The conventional working temperature of lithium-ion batteries is between -20 ℃ and 60 ℃. However, generally, when the temperature is below 0 ℃, the performance of lithium-ion batteries will decrease, and the discharge capacity will correspondingly decrease. Therefore, the working temperature for...
