德国尼克NICK蓄电池NCG120-12 12V120AH性能稳定可靠
The performance parameters of batteries mainly includeelectromotive force, capacity, specific energy, and resistance. Byusing batteries as an energy source, stable voltage, stablecurrent, long-term stable power supply, and minimal externalinfluence can be obtained. The battery structure is simple, easy tocarry, and the charging and discharging operations are simple andeasy to operate. It is not affected by external climate andtemperature, and its performance is stable and reliable. It hasplayed a significant role in various aspects of modern sociallife. 
The discharge rate represents the discharge current of abattery, which can be divided into time rate and current rate. Thedischarge time rate refers to the length of time it takes for thebattery to discharge to the discharge termination voltage at acertain discharge capacity. For example, in a 25 ℃ environment, ifthe battery is discharged at the current It to the dischargetermination voltage, the discharge process is called the t-hourrate, and the discharge It is called the t-hour rate dischargecurrent. According to IEC standards, the discharge time rate has20, 10, 5, 3, 1, 0.5 hour rates, and minute rates. The dischargecurrent rate is set to compare the current sizes of batteries withdifferent rated capacities. The t-hour rate discharge current isexpressed in It, usually represented by the 10 hour rate current asthe standard I10.
