How to use lead -acid batteries.18650 li ion rechargeable battery wholesaler

　　The charging method of lead -acid batteries is a very general saying; different types of lead -acid batteries, different application scenarios, and different discharge depths have different charging methods.

　　There are many types of lead -acid batteries. At present, the most widely used valve -controlled closed batteries (the AGM batteries that are often said to refer to this category), valve -controlled closed colloid battery (generally referred to as colloid or GEL battery) Three types; of course, there are low market shares such as 0pzv, OPZS, and winding type, and are not listed in this article.

　　According to application scenarios, cars start, communication, electricity, electric bicycles and electric vehicles.

　　The so -called discharge depth is the percentage of the amount of power from the battery. For example, a battery of 100 amp is released at 30 amp, and the discharge depth is 30/100 = 30%dod. Among them, DOD is DEPTHOFDISCHARGE is an abbreviation of discharge depth. In addition, the rated voltage of common lead -acid batteries is 12V, with 2V and 6V, and 4V and 16V are relatively rare. This is because each CE11 of the lead -acid battery or the rated voltage of the unit of the unit is 2V. In order to obtain a higher voltage, multiple units are often connected into one, and the 6 units are connected into one, that is, 12V, so as to use it with 12V, so that it is 12V, so that it is 12V. This type.

　　This article briefly describes the category of charging at 25 ° C at room temperature at 25 ° C.

　　Charger or charger

　　DC voltage meter DC current meter

　　Timer

　　Determine the rated voltage and rated capacity of the battery or battery pack. The rated voltage is used to determine the charging voltage, and the rated capacity is used to determine the charging current.

　　Regarding voltage: The easiest way is to read from the label; for example, the rated voltage of the CSB battery displayed in Figure 1 below is 12V.

　　If the label is worn or there is no label at all, it can be judged from the number of exhaust holes or safety valves. The exhaust pores are round holes that can be opened or opened at the top of the battery. To be sure, all lead -acid batteries currently have exhaust holes. Each exhaust hole represents a unit, which is 2V, and the total voltage of 12 exhaust holes is 24V.

　　Regarding the capacity: You can also read or calculate it from the label; in general, the rated voltage of the battery will be indicated on the label. The three PNP batteries are indicated as 65AH, but the UPS battery is usually represented by W. For this type of battery, the simple calculation method of the capacity is that the Watsu is divided by four, that is, 8.5AH; but when it encounters Figure 2, there is no way. Large, in general, the 12V100AH AGM battery weighs 30 ~ 35 kg, so if the battery weighs 500 kg in Figure 2, it can calculate its capacity of about 700AH.

　　If you only need to use the method introduced by this article once, you can skip this step; if you need to use it for a long time, it is recommended to implement this step carefully, that is, determine the opening voltage when the battery is 100%full. 0cv (OpenCircuitVoltage, opening voltage) at 0CV (Power Status).

　　Determine the charging voltage.

　　The charging voltage is divided into floating charging voltage, average charging voltage, fast charging voltage, etc. Generally speaking, the floating charging voltage is used in daily floating charging, minimum; it is used when it is charged and then charged, which is high; fast charging is the rapidly full charging voltage in emergency scenes, the highest, not commonly used.
