Battery capacity refers to the amount of electricity, which can also be understood as "volume". Below, we will delve into the detailed meaning of battery capacity from several aspects such as battery capacity units, battery capacity calculation, battery capacity testing, and battery capaci...

A dry battery is a maintenance free valve controlled battery with an opaque outer shell, and the liquid cannot be seen when opening the filling hole. Dry batteries require almost no maintenance, saving time and effort!The outer shell of a water battery is usually transparent, and the electrolyte ins...

What is the internal resistance of 18650 lithium-ion batteries?For 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 resista...

Correct charging and maintenance methods for 18650 lithium batteries. The working principle of 18650 lithium batteries is nothing more than charging to reserve energy, discharging to convert it into other energy and release it. When in an idle state without charging or discharging, there are three m...

Nowadays, cars generally use maintenance free batteries, and a car battery generally has a service life of about 3 years. The original battery of a new car can be used for more than 3 years. In addition, if you frequently travel long distances, it may take longer. If you run more in the city, it usu...

20a lithium batteryElectric vehicles are divided into two types: electric and electric motorcycles. The mileage of electric vehicles is determined by the capacity of the battery pack. First of all, for electric vehicles, the 48V12A can run about 40 kilometers, the 48V20A and 64V12A can run about 70...

Whether it is an electric bike that exceeds the standard or a national standard electric bicycle, it will be a means of transportation for the general public in the near future. Electric bicycles or electric bicycles have entered thousands of households and are closely related to people's lives...

The maximum charging current that lithium-ion batteries can accept is usually 1C or even smaller. The so-called 1C charging rate refers to charging at a current rate of 1 times the capacity, with a charging time of 1 hour. In fact, to achieve a long lifespan of lithium-ion batteries, it is basically...

A regular battery, also known as a lead-acid battery, has electrodes composed of lead and lead oxides, and the electrolyte is an aqueous solution of sulfuric acid. The important advantages are stable voltage and affordable price; The disadvantage is frequent daily maintenance. Old style ordinary bat...

Lithium-ion battery: It is a secondary battery (rechargeable battery) that mainly relies on the movement of lithium ions between the positive and negative electrodes to work. During charging and discharging, Li+ is inserted and removed back and forth between the two electrodes: during charging, Li+...
