Batteries have a code that indicates the size and type of battery. This code differs depending on the specification of the battery construction. There are 3 different specifications in the world that regulate the size, power and performance of batteries and they are the European (EN), the Japanese (JIS) and the American (BCI).
European standard batteries use 2 types of codes. One comes from the older coding according to the German DIN standard and the other is the newer coding according to the European Union (EN) standard. It is always five digits and consists of two parts:
Energy or Nominal Energy (Wh (for a specific C-rate)) – The “energy capacity” of the battery, the total Watt-hours available when the battery is discharged at a certain discharge current (specified as a C-rate) from 100 percent state-of-charge to the cut-off voltage.
The Ampere-Hour Capacity varies with the rate at which the battery is discharged; the slower the discharge, the greater the amount of electricity that the battery will deliver. The Ampere-Hour Capacity is the amount of electricity that a battery will deliver during 20 hours before the voltage falls to 10.50V.
A middle three-digit number that is characteristic of the polarity and capacity of the battery and may vary by manufacturer. E.g. 059 is used for the right position of the positive terminal. The last three-digit number that shows the cold start performance of the battery in tens according to the European standard.
It is this voltage that generally defines the “empty” state of the battery. Capacity or Nominal Capacity (Ah for a specific C-rate) – The coulometric capacity, the total Amp-hours available when the battery is discharged at a certain discharge current (specified as a C-rate) from 100 percent state-of-charge to the cut-off voltage.

Batteries are marked with nominal voltage; however, the open circuit voltage (OCV) on a fully charged battery is 5–7 percent higher. Chemistry and the number of cells connected in series provide the OCV. The closed circuit voltage (CCV) is the operating voltage. Always check for the correct nominal voltage before connecting a battery.

The current energy level of a battery compared to its maximum capacity is known as the State of Charge (SoC) of that battery. SoC is represented in percentage. In simple words, you can call SoC a fuel gauge for batteries, as it tells you how much electrical charge is left behind before a battery needs recharging. In contrast, if you want to know how much energy …
