Cold start current and test standard
The battery tester requires the cold start
current in amps and the test standard (IEC,
DIN, SAE, EN, JIS) as a reference value for the
purpose of assessing a battery. A
battery test is contingent

of this reference value.
Battery temperature
The start performance of a battery is greatly
dependent on temperature. In order to arrive
at a reliable test statement it
essential to enter the temperature range of
the battery
(< 0 °C or > 0 °C) next to cold
start current and a test standard. Of signifi-
cance when selecting the temperature range
is the battery temperature, not the ambient
temperature.

3.3 Important tips on testing batteries
New, ready-for-installation, charged starter
batteries, which have been in storage for a
lengthy period, will generally achieve their
full starting power after a few weeks
driving operation.
Dry, charged batteries

!
Testing a dry, charged battery after filling
can lead to an incorrect assessment of the
battery.
Any charging operation or current consump-
tion activates electrochemical reactions in
a battery which persist after charging/con-
sumption.
The battery test delivers
charging or current consumption has taken
place on the battery for at least one hour
prior
to the test.
i
Charging the battery leads to a temporarily
excessively high voltage and the Battery-Test
would assess the battery with a result that
is too critical.
i
If the Battery-Test were be reversed, the
battery would be assessed as being good
during a load or shortly after discharging a
high current.
