Lead-acid starter batteries - Part 1: General requirements and methods of test

This standard is applicable to lead-acid batteries with a nominal voltage of 12 V, used primarily as a power source for the starting of internal combustion engines, lighting and also for auxiliary equipment of internal combustion engine vehicles. These batteries are commonly called "starter batteries". Batteries with a nominal voltage of 6 V are also included within the scope of this standard. All referenced voltages have to be divided by two for 6 V batteries. This standard is applicable to batteries for the following purposes: - batteries for passenger cars, - batteries for commercial and industrial vehicles for normal use, - batteries for commercial and industrial vehicles for severe use. This standard is not applicable to batteries for other purposes, for example the starting of railcar internal combustion engines.

Batteries d'accumulateurs de démarrage au plomb - Partie 1: Prescriptions générales et méthodes d'essais

La présente norme est applicable aux accumulateurs au plomb, d'une tension nominale de 12 V utilisés principalement comme source de courant, pour le démarrage des moteurs à combustion interne, ainsi que pour l'éclairage et les installations auxiliaires des véhicules équipés de moteur à combustion interne. En langage pratique, ce type d'accumulateur est appelé "batterie de démarrage". Les batteries ayant une tension nominale de 6 V font également partie du domaine d'application de cette norme. Pour les batteries de 6 V, toutes les tensions spécifiées doivent être divisées par deux. Les applications de ces accumulateurs sont les suivantes: - batteries pour véhicules de tourisme, - batteries pour véhicules commerciaux, utilitaires et industriels en usage normal, - batteries pour véhicules commerciaux, utilitaires et industriels en usage intensif. Cette norme ne s'applique pas aux batteries destinées à d'autres utilisations telles que le démarrage des moteurs à combustion interne des autorails.

Svinčeve starterske baterije – 1. del: Splošne zahteve in preskusne metode

Ta standard se uporablja za svinčeno-kislinske baterije z nazivno napetostjo 12 V, ki se uporabljajo predvsem kot vir napajanja za zagon motorjev z notranjim izgorevanjem, razsvetljavo in tudi za pomožno opremo vozil z motorji z notranjim izgorevanjem. Običajen te baterije imenujemo »zaganjalne baterije«. Tudi baterije z nazivno napetostjo 6 V so zajete v področje uporabe tega standarda. Vse navedene napetosti je treba v primeru baterij z napetostjo 6 V deliti z 2. Ta standard se uporablja za baterije za naslednje namene: baterije za potniške avtomobile, baterije za komercialna in industrijska vozila za običajno uporabo, baterije za komercialna in industrijska vozila za izredno uporabo. Ta standard se ne uporablja za baterije za druge namene, na primer za zagon železniških motornih vozil z motorjem z notranjim izgorevanjem.

- 5 - EN 50342-1:2006 1.4 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 4.2.1), the electrolyte density or OCV shall be within the ranges specified in 1.3; − or in a dry-charged state not filled with electrolyte. The density of the acid to fill such batteries before use shall be in the range 1,27 kg/l to 1,30 kg/l at 25 °C unless otherwise specified by the manufacturer. 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. 2 General requirements 2.1 Identification, labelling Batteries according to this standard shall bear the following characteristics on at least one of their sides or on the top surface: a) the identification of manufacturer or supplier; b) the nominal voltage, i.e. 12 V or 6 V; c) the capacity: − either nominal capacity Cn (Ah) (see 3.1.2), − or nominal reserve capacity Cr,n (min) (see 3.1.2), The values of Cn or Cr,n for all batteries shall correspond to the electrolyte density or OCV given in 1.3; d) the nominal cranking current Icc (see 3.1.1); e) the six coloured symbols as specified in Annex A, Safety labelling; f)
the marking for the separate collection and recycling according to EN 61429; g) valve regulated batteries shall be marked ‘VRLA'. NOTE
Batteries may be marked with other information such as the filling and charging date (see 4.1). 2.2 Marking of the polarity This shall be in accordance with: EN 60095-2 Part 2: Dimensions of batteries and dimensions and marking of terminals EN 60095-4 Part 4: Dimensions of batteries for heavy commercial vehicles

For the correlation (relationship) of Cn and Cr,n, see Annex B. 3.1.3 The charge acceptance is expressed as the current Ica which a partially discharged battery accepts at 0 °C and a constant voltage of 14,40 V (see 5.4). 3.1.4 Charge retention is measured by the cold cranking performance of the charged and filled battery after storage on open circuit under defined conditions (temperature, time - see 5.5).

- 7 - EN 50342-1:2006 3.1.5 The endurance test consists of two parts 3.1.5.1 Corrosion test represents the ability of a battery to perform repeated overcharge/storage periods (see 5.6 and 5.7). 3.1.5.2 Cycling test represents the ability of a battery to perform repeated discharge/recharge cycles and long rest periods on open circuit. This ability shall be tested by a series of cycles and rest periods under specified conditions after which the cold cranking performance shall be determined (see 5.6 and 5.7). 3.1.6 Water consumption is defined as g/Ah Ce or g/min Cr,e (see 3.1.2 and 5.8). Valve regulated batteries have a very low water consumption and are not intended to receive addition to the electrolyte (see 5.8.2). 3.1.7 Dry-charged battery: A new battery may be designated as dry-charged if it can be activated -ready for service- by filling it with the defined electrolyte (see 1.3 and 1.4) and in accordance with any specific instructions from the manufacturer and if it then conforms to the requirements of 5.11. 3.2 Mechanical characteristics 3.2.1 Vibration resistance represents the ability of a battery to maintain service under acceleration forces. Requirements are verified by the test defined in 5.9. 3.2.2 Electrolyte retention is the ability of a battery to retain electrolyte under specified mechanical conditions (see 5.10). Valve regulated batteries are submitted to a special test (see 5.10.2). 4 General test conditions 4.1 Sampling of batteries All tests shall be carried out on new battery samples. Samples shall be considered as new no later than − 30 days after the acid filling and formation date in the case of filled and charged batteries, − 60 days after shipment date of the manufacturer in the case of dry-charged batteries. 4.2 Preparation of batteries prior to test - Definition of a fully-charged battery All tests, except that in 5.11, shall commence with fully-charged batteries. Batteries shall be considered as fully-charged if they have undergone the charging procedures of 4.2.1 for vented batteries or 4.2.2 for valve regulated batteries. 4.2.1 Charging of vented batteries The battery shall be charged at a voltage of 16,00 V ± 0,10 V for 24 h with the maximum current limited to 5 In (see 3.1.2). The battery temperature shall be maintained in the range 25 °C to 35 °C. If necessary, an appropriate environmental control system shall be used, e.g. a water bath. In the case of recharging after a test for cranking performance (according to 5.3) the charging time may be limited to 16 h.
