DELTA蓄电池DT12012俄罗斯12V1.2AH应急安全电源
蓄电池温度与容量
当蓄电池温度降低，则其容量亦会因以下理由而显著减少。
（A）电解液不易扩散，两极活性物质的化学反应速率变慢。
（B）电解液之阻抗增加，电瓶电压下降，蓄电池的5HR容量会随蓄电池温度下降而减少。
The discharge rate represents the discharge current of a battery,which can be divided into time rate and current rate. The dischargetime rate refers to the length of time it takes for the battery todischarge to the discharge termination voltage at a certaindischarge capacity. For example, in a 25 ℃ environment, if thebattery 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.
