|Capacité (Ah)
|Quantité de courant que peut stocker ou restituer une batterie 
généralement spécifiée en Ah pour un régime de décharge donné

|Tension (V)
|Niveau de tension de la batterie. Doit être compatible avec les organes connectées
|Les batteries au plomb sont constituées d'éléments délivrant chacun une tension de 2,1 V. Le montage en série de ces éléments permet d'atteindre les voltages usuels souhaités, en général 12 V, soient 6 éléments. Pour réaliser des systèmes en 24 ou 48 V, on monte des batteries 12 V en série.<br />

|-
Capacity (Ah) 
|The amount of current that a battery can store or release, usually specified in Ah for a given discharge rate.
|A 10 Ah battery can produce 5 Amperes (A) for 2 hours (h).
|-
|Tension (V) 
|Battery voltage level. It must be compatible with the connected devices.
|Lead-acid batteries are made up of units delivering 2.1 Volts (V) and connecting these units in series makes it possible to reach the generally desired voltage. For example, six units connected in series deliver 12 V. To create 24 V or 48 V systems, 12 V batteries are, in turn, connected in series.
|-
Energy (Wh) 
|The product of multiplication of the capacity by the voltage.

Discharge rate, C<sub>xx</sub> 
|Expressed  as a unit of C<sub>10</sub>, C<sub>20</sub>or C<sub>100</sub>, it indicates the capacity of a battery according to its rate of discharge.

Characteristic Definition Explanation
The amount of current that a battery can store or release, usually specified in Ah for a given discharge rate. A 10 Ah battery can produce 5 Amperes (A) for 2 hours (h).
Tension (V) Battery voltage level. It must be compatible with the connected devices. Lead-acid batteries are made up of units delivering 2.1 Volts (V) and connecting these units in series makes it possible to reach the generally desired voltage. For example, six units connected in series deliver 12 V. To create 24 V or 48 V systems, 12 V batteries are, in turn, connected in series.
The product of multiplication of the capacity by the voltage. A 200Ah 24V battery will have an energy of 4800 Watts hour (Wh).
Expressed as a unit of C10, C20or C100, it indicates the capacity of a battery according to its rate of discharge. 50Ah C20battery means a battery of 50Ah capacity with 20h discharge

C100battery: 90Ah (capacity of 90Ah with a discharge in 100h).

This is the maximum extractable current from a battery over a short period when starting the engine, for example. CCA 420A 5 sec indication means the battery can deliver 420A for 5 sec.
State of charge of a battery, which indicates the amount of electricity remaining. SOC = 50 %: the battery’s charge is 50%.
State of discharge of a battery, or the amount of electricity consumed. DOD + SOC = 100% .
For a battery, a cycle represents a discharge followed by a charge. The number of cycles of a battery depends on the depth of discharge or amount of electricity consumed. The higher the DOD, the lower the cycle life, the same battery can have.
