4 Designation of starter batteries — Electrolyte density and open circuit voltage
4.1 Designation according to type
Batteries are designated according to their type, as follows:
• flooded batteries (vented);
• enhanced flooded batteries, EFB;
• valve regulated lead-acid batteries, VRLA;
— absorbent glass mat batteries, AGM;
— gel batteries.
4.2 Dry-charged batteries
Lead-acid batteries may be supplied in a dry-charged state. Dry-charged batteries can be activated by filling with the defined electrolyte indicated by internal or external marks or according to the manufacturer’s activation instructions. After activation, these batteries are ready to use.
4.3 Electrolyte density and open circuit voltage
The density of the electrolyte in all fully charged vented batteries shall be in the range of
1,27 kg/I to 1,30 kg/I at 25 °C unless otherwise specified by the manufacturer.
NOTE For valve-regulated batteries, the electrolyte is not accessible and, therefore, its density cannot be checked.
The open circuit voltage (CCV) at 25 °C, of fully charged batteries after a minimum 24 h stand on open circuit, shall be in the range of 12,70 V to 12,90 V for vented types and 12,80 V to 13,10 V for valve regulated types unless otherwise specified by the manufacturer.
The manufacturer shall specify the value and tolerance of the electrolyte density or CCV. If such information is not available, vented battery testing shall be carried out with a density of 1,28 kg/I ± 0,01 kg/I at 25 °C or an CCV of 12,76 V ± 0,06 V at 25 °C and valve regulated battery testing shall be carried out with a minimum CCV of 12,80 V.
5 Condition on delivery
New vented batteries may be supplied either:
• in a state ready for use, or
• in a dry-charged (or charge-conserved) state not filled with electrolyte. The density of the electrolyte to fill these batteries before use (unless otherwise recommended by the manufacturer) shall be:
— 1,28 kg/I ± 0,01 kg/I at 25 °C;
Valve-regulated batteries are normally supplied in a state ready for use.
6 General requirements
6.1 Identification, labelling
6.1.1 General
Batteries complying with this document shall bear the following characteristics on at least the
top or one of their four sides.
6.1.2 The identification of manufacturer or supplier
The name of the manufacturer or supplier shall be indicated.
6.1.3 Nominal voltage: 12 V
The nominal voltage of 12 V shall be indicated.IEC 60095-1 pdf download.
