Battery Marking

Battery marking

Performance
The performance of a car battery is normally expressed as follows:
- Cold cranking amperes, CCA. See the explanation in Terminology Terminology
- Reserve capacity, RC. See the explanation in Terminology Terminology
- Capacity, C20 (in certain cases). See the explanation in Terminology Terminology.

Recommended charge current
The cold cranking amperes according to the SAE and DIN norms and the corresponding capacity and recommended charge current are shown in the table below.











Volvo battery labels
The illustrations show an example of how the battery labels may appear.





European label

1. Cold cranking amperes, CCA, according to the SAE norm (520 A)
2. Volvo part number (9472329)
3. Reserve capacity, RC, according to the SAE norm (95 min)
4. The nominal terminal voltage of the battery (12 V)*.





American labels

1. The nominal terminal voltage of the battery (12 V)*
2. Capacity (60 Ah)
3. Cold cranking amperes, CCA (550 A)
4. Reserve capacity, RC (100 min)
5. Volvo part number (9459947).
* 12 V is the nominal terminal voltage. This means that the battery has a stand-by voltage of 12.72 V when fully charged. Note that a battery with a stand-by voltage of 12 V is only charged to approximately 35% of capacity (see the diagram in Design and function Design and Function ).
