3 Condition on delivery
New vented batteries may be supplied either
— in a state ready for use, filled with the appropriate electrolyte to the maximum level. After an initial charge (according to 6.2.1 and 6.2,2), the electrolyte density shall correspond to the relevant figures of 2.3;
— in a dry-and-charged (or charge-conserved) state not filled with electrolyte. The density of the acid 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 for class A and B, and
1,23 kg/I ± 0,01 kg/I at 25 °C for class AT and BT.
Valve-regulated batteries are normally supplied in a state ready for use. For these batteries, the electrolyte is not accessible and, therefore, its density cannot be checked.
4 General requirements
4.1 Identification, labelling
Batteries according to this standard shall bear the following characteristics on at least the top or one of their four sides in indelible print:
4.1.1 Class of battery: (PEG) A or B or AT or BT (see 2.3).
4.1.2 Nominal voltage: 12 V
4.1.3 Capacity:
— either nominal capacity C,. (Ah), or
— reserve capacity Cr (mm).
The values C or Cr for all classes of batteries according to 4.1.1 shall correspond to the electrolyte density given in 2.3.
4.1A Nominal cranking current: I (see 5.1.1)
4.1,5 Safety labelling
Batteries shall be marked with the six coloured symbols as described in B.1. However, to be in compliance with some national regulations, additional wording or special labelling can be used (for example safety label for North America area shown in B.2).
4.1.6 Valve-regulated batteries shall bear a special indication.
4.2 Marking of the polarity
According to clause 14 of IEC 60095-2, at least the positive terminal shall be identified by a “i” mark on the lid or on the terminal itself.
6.2 Preparation of batteries prior to test — Definition of a fully-charged battery All tests, except that in 7.12, shall commence with fully-charged batteries.
Vented batteries shall be considered as fully-charged if they have undergone one of the two charging procedures of 6.2.1 or 6.2.2 carried out at 25 °C ± 10 °C.
Valve regulated batteries shall be charged according to the procedure of 6.2.3 at 25 °C ± 10 °C (if necessary, an appropriate temperature control system shall be used, for example a water bath).
6.2.1 Charging of vented batteries at constant current The battery shall be charged
— at a current 012 !(see 5.1.2), until the voltage reaches 14,40 V, and
— then with the same current for a further 5 h.
In the case of recharging after a test for cranking performance (according to 7.3), the time shall be limited to 3 h instead of 5 h.
6.2.2 Charging of vented batteries at modified constant voltage
The battery shall be charged at a voltage of 16,00 V for 24 h with the maximum current limited to 5 In (see 5.1.2).
In the case of recharging after a test for cranking performance (according to 7.3) the charging time may be limited to 16 h.
NOTE If neither complete knowledge of the batlery construchon nor a specification from the manufacturer is available, then charging according to the present subclause Is recommended.
6.2.3 ChargIng of valve regulated batteries
Unless otherwise recommended by the manufacturer, the battery shall be charged
— at a constant voltage of 14,40 V for 20 h with the maximum current limited to 5 I,, (see 5.1.2),
— then with a constant current of 0,5 I for 4 h.
6.3 Activation of dry-charged or charge-conserved batteries
Dry charged batteries shall be filled with the appropriate electrolyte (according to 2.3) to the maximum level indicated by internal or external marks of the battery or according to the manufacturer’s instructions.
6.4Measuring instruments
6.4.1 Electrical measuring instruments
The range of instruments used shall be appropriate for the magnitude of the voltage or currentto be measured.
For analogue instruments, the readings shall be taken in the top third of the scale.- Voltage measurement
The instruments used for measuring voltages shall be voltmeters having an accuracy ofclass 1 or better.The resistance of the voltmeters shall be at least 300 o/v.
Current measurement
The instruments used for current measurement shall be ammeters having an accuracyclass of 1 or better. The assembly of ammeter，shunt and leads shall have an overalaccuracy of class 1 or better.
