Introduction
The life of lead acid batteries is limited to several
years and while working batteries loose capacity. When
the battery capacity becomes unacceptably small, bat-
tery needs to be replaced. It is exceptionally important
to determine correct time of battery replacement. If a
battery is replaced too early – the owner of a battery
looses money. If a battery is replaced too late, the loss
could be even larger.
Qulon-12ns - lead acid battery capacity indicator
is a device for battery capacity estimation. With Qulon,
one can sort 12-volt batteries by their capacity and re-
ject batteries that have lost capacity.
Memory for keeping test results helps user dur-
ing testing large amount of batteries.
The battery capacity estimation is based on the
dependence between battery capacity and battery abil-
ity to conduct electric current. Battery capacity indicator
sends a test pulse to a battery and analyses the battery
answer. Qulon-12ns utilises the most up-to-date method
of battery capacity estimation taking into account the
multifrequency battery response to test pulses.
Different battery producers use different techno-
logies and battery designs. Therefore, the dependence
between test pulse form and value and battery answer
form and value could be slightly different. That is why
Qulon-12ns is not a high precision device for capacity
measurement. It estimates battery capacity
