Understanding lead-acid battery coding

The car battery shall be marked with a code according to its specifications. This code can be Complicated and is defined based on different standards of coding.

DIN Number (German Industrial Standard):

1^st digit = Battery Voltage

(1-2 = 6 Volt & 5-7 = 12 Volt)

2^nd & 3^rd digits = Nominal capacity

(e.g., 560 = 60Ah @ 20-hour rate / 660 = 160Ah @ 20-hour rate)

4^th & 5^th digits = unique code

(Referring to the specifications of battery such as terminals types, vibration and endurance level and …)

ETN Number (European Type Number):

1^st digit = Battery Voltage

(1-2 = 6 Volt & 5-7 = 12 Volt)

2^nd & 3^rd digits = Nominal capacity

(e.g., 560 = 60Ah @ 20-hour rate / 660 = 160Ah @ 20-hour rate)

4^th, 5^th & 6^th digits = unique code

(Referring to the specifications of battery such as terminals types, vibration and endurance level and …)

7^th, 8^th and 9^th digits = Cold Cranking Performance

Cold Cranking Performance (Amps)
(Cold Cranking Performance (CCA) is the starting ability of the battery in specific conditions. It may introduce in accordance with different standards such as SAE, DIN or EN)
