通常电源设备的容量用kv·a或kw来表示。作为电源的vrla电池，选用安时（a·h）表示其容量则更为准确，蓄电池容量定义为∫t0tdt，理论上t可以趋于无穷，但实际上当电池放电低于终止电压后仍继续放电，这可能损坏电池，故t值有，电池行业中，以小时（h）表示电池的可持续放电时间，觉的有c24、c20、c10、c8、c3、c1等标称容量值。

Generally, the capacity of power supply equipment is expressedin kV · a or kW. However, for VRLA battery as a power supply, it ismore accurate to use ampere hour (a · h) to represent its capacity.The battery capacity is defined as ∫ t0tdt. Theoretically, t cantend to infinity, but in fact, when the battery discharge is lowerthan the termination voltage, it will continue to discharge, whichmay damage the battery. Therefore, the value of T is. In thebattery industry, hours (H) represents the sustainable dischargetime of the battery, and it is perceived that there are C24, C20,C10, C8, C3, C1 and other nominal capacity values.

小电池的标称容量以毫安时（ma·h）计，大电池的标称容量则以安时（a·h）、千安时（ka·h）计，电信工业常取c10、c8等标称容量值。例如，常见的deka电池12avr100sh为12v单体，100a·h容量，即可持续放电10h，电流为10a,共放出安时数为10*10=100a·h（实际测试中，为使电流值保持恒稳，当电压变化时，应调整外电路负载，以便计量）。

The nominal capacity of small batteries is measured inmilliampere hours (MA · h), while the nominal capacity of largebatteries is measured in ampere hours (a · h) and kiloampere hours(KA · h). The nominal capacity values such as C10 and C8 are oftentaken in the telecommunications industry. For example, the commonDeka battery 12avr100sh is a 12V monomer with a capacity of 100 a ·h, which can discharge continuously for 10h, the current is 10a,and the total discharge ampere hours is 10*10=100 a · H (in theactual test, in order to keep the current value stable, when thevoltage changes, the external circuit load should be adjusted formeasurement).

电动车用蓄电池的容量以下列条件表示之：

The capacity of battery for electric vehicle is indicated by thefollowing conditions:

电解液比值1．280/20℃

Electrolyte ratio 1.280/20 ℃

放电电流5小时的电流

Discharge current 5 hour current

放电终止电压1．70v/cell

Discharge termination voltage 1.70v/cell

放电中的电解液温度30±2℃

Electrolyte temperature in discharge: 30 ± 2 ℃

1．放电中电压下降 放电中端子电压比放电前之无负载电压（开路电压）低，理由如下：

1. the voltage drops during discharge. The terminal voltageduring discharge is lower than the no-load voltage (open circuitvoltage) before discharge. The reasons are as follows:

1．v=e-i.r

v：端子电压（v） i：放电电流（a）

v: Terminal voltage (V) I: discharge current (a)

e：开路电压（v） r：内部阻抗（ω）

e: Open circuit voltage (V) r: internal impedance（ ω）

2．放电时，电解液比重下降，电压也降低。

2. when discharging, the specific gravity of electrolytedecreases and the voltage also decreases.

3．放电时，电池内部阻抗即随之增强，完全充电时若为1倍，则当完全放电时，即会增强2～3倍。

3. when discharging, the internal impedance of the battery willincrease. If it is 1 time when fully charged, it will increase 2 ~3 times when fully discharged.

用于起重时电瓶电压之比用于行走时的电压低，乃是由于起重用之油压马达比行走用之驱动马达功率大，放电流大，则上式的i.r亦变大。

The reason why the battery voltage is lower when it is used forlifting than when it is used for walking is that the power of thehydraulic motor used for lifting is greater than that of thedriving motor used for walking, so the discharge current is large,and the I.R of the above formula is also large
