3.2.5
gel batteries
VRLA batteries in which the electrolyte is immobilized by fixing as gel
3.3 Condition on delivery
3.3.1 Specific gravity of electrolyte and open circuit voltage
Specific gravity of electrolyte and open circuit voltage of a lead acid battery depend on its state of charge and
temperature.
The specific gravity of the electrolyte of fully charged vented batteries shall be in the range 1,27 kg/l to
1,30 kg/l at 25 °C unless otherwise specified by the manufacturer.
The open circuit voltage (OCV), of fully charged batteries after a minimum of 24 h stand on open circuit, shall
be in the range 12,70 V to 12,90 V for vented types and 12,80 V to 13,00 V for valve regulated types at 25 °C
unless otherwise specified by the manufacturer.
3.3.2 Definition of fully charged new battery
New vented batteries may be supplied:
- either in a state ready for use, filled with the appropriate electrolyte to the maximum level. 24 h after an
initial charge (according to 5.2), the specific gravity of electrolyte or OCV shall be within the ranges
specified in 3.3.1. In batteries with lids without plugs checking specific gravity of electrolyte is generally
not possible. In these cases, only OCV shall be checked according to 3.3.1;
6
---------------------- Page: 8 ----------------------
SIST EN 50342-1:2016
EN 50342-1:2015 (E)
- or dry charged as defined in Clause 7.
Valve regulated batteries are normally supplied in a state ready for use. After an initial charge according to 5.2
followed by a 24 h rest period, the OCV shall be within the range specified in 3.3.1. For these batteries, the
electrolyte is not accessible and therefore its specific gravity cannot be checked.
3.4 Electrical characteristics
3.4.1 The cranking current I , to be indicated by the manufacturer, is the discharge current which the
cc
battery can supply at –18°C for 10 s to a minimum voltage U = 7,50 V and meeting requirements of a
f
simulated cranking profile according to 6.2. It is used as well to check the high current discharge performance
according to 6.3.
3.4.2 The capacity of a starter battery is defined for the temperature of 25 °C ± 2 °C. The nominal capacity
C in this standard is a C20. It shall be indicated by the manufacturer as nominal 20 h capacity C20 (Ah).
n
The nominal 20 h capacity C is the electric charge (in Ah) that a battery can supply with a current:
n
C
n
I = (A)
n
20 h
to a final voltage U = 10,50 V.
f
The effective capacity C shall be determined by discharging a battery with constant current I to U = 10,50 V
e n f
(see 6.1).
3.4.3 The charge acceptance is expressed as the current I which a partially discharged battery accepts at
ca
0 °C and a constant voltage of 14,40 V (see 6.4).
3.4.4 Charge retention is measured by the high current discharge performance of the charged and filled
battery after storage on open circuit under defined conditions of temperature and time (see 6.5).
3.4.5 The Cycling test represents the ability of a battery to perform repeated discharge / recharge cycles.
This ability shall be tested by a series of cycles under specified conditions after which the cold cranking
performance and the 20 h capacity shall be determined (see 6.6).
3.4.6 The Corrosion test checks the resistance of a battery against overcharging at increased temperatures
(see 6.7)
3.4.7 The Deep discharge test represents the ability of battery to overcome an over discharge in a vehicle
by small loads during parking for a long time (see 6.8)
3.4.8 Water consumption test checks if the battery can keep its performance under extended exposure to
heat and overcharge conditions. It is measured as loss of weight during overcharge of a fully charged battery
and is defined as g/Ah C (see 6.9).
e
3.5 Mechanical characteristics
3.5.1 Vibration resistance represents the ability of a battery to maintain service under acceleration forces.
(see 6.10)
3.5.2 Electrolyte retention is the ability of a battery to retain electrolyte under specified mechanical
conditions (see 6.11).

0 Introduction
0.1 Object
The object of this standard is to specify
− general requirements;
− certain essential functional characteristics, the relevant test methods and results required, for
several classes and types of starter batteries.
0.2 Designation of starter batteries
Batteries are classified according to their types
Battery type Definition
Flooded or a secondary battery having a cover provided with one or more
vented openings through which gaseous products may escape
batteries
EFB batteries are enhanced vented (flooded) secondary batteries, with
additional special design features to significantly improve the cycling
capability compared to standard flooded batteries. These batteries shall
have a water consumption performance level of W3, W4 or W5.
Valve a secondary battery which is closed under normal conditions but which
regulated
has an arrangement that allows the escape of gas if the internal
batteries pressure exceeds a predetermined value. The battery cannot receive
addition to the electrolyte.
In Valve Regulated batteries, the electrolyte is immobilized.
In case electrolyte is immobilized by absorbing in a glass mat this type
of VRLA-battery is called AGM-battery (Absorbent Glass Mat).
In case electrolyte is immobilized by fixing as gel this type of VRLA-
battery is called GEL- battery
0.3 Condition on delivery
0.3.1 Electrolyte density and open circuit voltage
Electrolyte density and open circuit voltage of lead acid battery are depending on state of charge and
temperature.
The density of the electrolyte in all fully charged vented batteries shall be in the range 1,27 kg/l to
1,30 kg/l at 25 °C unless otherwise specified by the manufacturer.
The open circuit voltage (OCV), of fully charged batteries after a minimum of 24 h stand on open
circuit, shall be in the range 12,70 V to 12,90 V for vented types and 12,80 V to 13,00 V for valve
regulated types at 25 °C unless otherwise specified by the manufacturer.
0.3.2 Definition of fully charged new battery
New vented batteries may be supplied
− either in a state ready for use, filled with the appropriate electrolyte to the maximum level. 24h
after an initial charge (according to 5.2), the electrolyte density or OCV shall be within the ranges
specified in 0.3.1.In batteries with lid without plugs checking electrolyte density is generally not
possible. In this cases OCV is to check only according 0.3.1.

− or dry charged as defined in chapter 7.
Valve regulated batteries are normally supplied in a state ready for use. 24 h after an initial charge
(according to 5.2) OCV shall be within ranges specified in 0.3.1. For these batteries the electrolyte is
not accessible and therefore its density cannot be checked.

1 Scope
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.
This standard is not applicable to batteries for other purposes, for example the starting of railcar
internal combustion engines or for motorcycles.
NOTE Separate standard for motorcycle batteries is under preparation.
