  Ampere hour (Ah): It is a unit used to define the capacity of a battery. When the battery is discharged, the value obtained by dividing the discharge current (ampere) by the duration of discharge (hour).

  Capacity: refers to the amount of electrical energy that a battery can provide, expressed in ampere hours (Ah). It is measured as the duration (in hours) of constant current discharge at a given termination voltage (usually 1.75V/cell) at a specified current value at a specific ambient temperature. The battery discharge capacity (in ampere hours Ah) is obtained by multiplying the current value (in amperes) by the discharge time (in hours).

  Battery: Composed of two or more single battery cells, usually connected in series, and sometimes single battery cells can also form a battery.

  Charging: This is the process of the battery regaining electrical energy. During the charging process, the voltage at the battery end will increase.

  Charging efficiency: It is the ratio of the discharge capacity (Ah) of the battery to the charge capacity (Ah) during recharging.

  Constant voltage charging: It is a charging method that controls the voltage. When using this method to charge the discharged battery, the charging current will gradually decrease. Constant voltage charging is a commonly used charging method for VRLA batteries.

  Constant current charging: It is a charging method that controls the current. By controlling the charging time, fixed charging can be performed. When using the constant current method to charge VRLA batteries, a timer needs to be installed to avoid overcharging.
