		abstract={Batteries have an important role in a railway traction substation, where when the main
source of PLN is interrupted / extinguished, the battery serves as the main source of
voltage control for operating and protective relays in the traction substation. In these
conditions the traction substation does not produce a voltage of 1500 Vdc and only acts
as a connecting substation between adjacent substations. In order to ensure the readiness
of battery operation as a DC back-up supply, therefore, measurements of the per cell
battery voltage, internal resistance and loading tests are carried out to determine battery
performance at the Kalideres station traction substation. After getting the results from
the loading test carried out for 5 hours, the data obtained is then processed using the
linear regression method to estimate how long the maximum time the battery can back up
DC loads in the traction substation until it reaches its minimum total voltage of 108 Vdc.
Based on the measurements and tests and data processing carried out, the leoch battery
resulted in the total battery voltage being above the reference standard and is estimated
to be able to serve the load for 7 hours. However, the resistance in the battery is in a fail
state and has passed the reference standard limit set so that it is necessary to
recondition/replace the battery. The results of the loading test after the reconditioning
resulted that the voltage and resistance values in the battery cell were in good condition
and it was estimated that the battery was able to serve DC loads of 5.40 A for 40 hours
with a total final voltage of 108.008 Vdc.}
