The reason why lithium battery chargers cannot charge lead-acid batteriesIt is generally not recommended to use it this way. Although chargers without pulse function can theoretically charge the battery, it may still harm the battery. Although the battery has a protective plate, it can theoretically...

After the new battery is put into use, it must be regularly charged and discharged. The purpose of charging is to enable the battery to store electrical energy and restore its capacity in a timely manner to meet the needs of electrical equipment. The purpose of discharge is to timely test the capaci...

The largest supercapacitor in industry has a diameter of 65mm and a length of mm. Volume=3. (pi) * 32.5 * 32.5 (square of radius) *=. cubic millimeters=cubic centimeters=ml. Supercapacitors can be divided into double-layer capacitors and pseudocapacitors based on energy storage mechanisms. It is a n...

Looking at the applicable environment, if the ambient temperature is high, generally speaking, based on 25 degrees, for every 10 degrees increase, the lifespan is reduced by half;There are also charging conditions. If there is frequent undercharging and less charging than discharging, it will quickl...

Which is better compared to lithium-ion batteries, nickel hydrogen batteries, or nickel cadmium batteries? Nickel hydrogen batteries are a combination of hydrogen ions and metallic nickel, with a 30% higher battery capacity than nickel cadmium batteries. They are lighter, have a longer lifespan, and...

What is the normal internal resistance of the batteryFor lithium-ion batteries, the internal resistance of the battery is divided into ohmic internal resistance and polarization internal resistance. Ohmic internal resistance is composed of electrode material, electrolyte, diaphragm resistance, and c...

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...
