Capacity: Refers to the battery can provide power, expressed in ampere hour (Ah), is in a certain environment temperature, in a specified current value, electricity to a given constant exile termination voltage (typically 1.75 V/single) the measurement duration time (hours), with the current value (amp) multiplied by the discharge time (hours) it is concluded that the battery discharge capacity (Ah).
Battery: Consists of two or more individual batteries, usually connected in series, sometimes a single battery can also form a battery.
Charging: The process by which the battery is recharged. During charging, the terminal voltage of the battery is increased.
Charging efficiency: Refers to the ratio of the battery discharge capacity (Ah) to the recharging capacity (Ah).
Constant current charging: it is a charging method to control the current. By controlling the charging time, the power can be fixed. When using constant current method to charge VRLA battery, need to install timer to avoid overcharging.
Terminal voltage: terminal voltage of the battery at the end of charge and discharge.
Cycle: the battery after a charge and a discharge is called a cycle.
Cycle life: the number of charge and discharge cycles a battery can provide before failure. Cycle life has a great relationship with the depth of discharge of the battery.
Cycle use: a method of use in which the battery is charged and discharged repeatedly.
Deep discharge: the battery discharges to 80 ~ 100% of its rated capacity.
Discharge depth: the percentage of the rated discharge capacity of the battery.
Discharge: Refers to the battery output current process.
Discharge rate: Usually expressed as a multiple of capacity (C), refers to the rate at which a battery discharges. Such as 0.1c discharge refers to the discharge of 0.1 times the capacity of the current (ampere).
