EnerSys SUPERFACE 12TM-200 Quick Manual

QUICK GUIDE TO ENERSYS TM SUPERSAFE BATTERY
1) INITIAL CHARGE PROCEDURE
It is possible that batteries will lose charge during storage and transportation. It must also be
noted that ENERSYS deliver SUPERSAFE batteries according to IEEE1188 standard which
requires batteries to leave the factory at 95% or greater state of charge. It is therefore
crucial that battery banks are properly charged prior to commissioning and acceptance
capacity testing.
NOTE: Improper initial charging will affect battery performance and lifetime.
STEP 1 – Initial Charger setup
Once the battery bank has been fully assembled and the connections checked, connect the
battery charger to the battery bank. Take care to ensure that the charger positive is
connected to the battery positive and the charger negative is connected to the battery
negative.
A) Count the number of cells (there should be 54 for a 125 V station battery !).
B) Measure the actual battery case temperature and check against the battery
temperature reading seen by the battery charger. Ensure the temperature readings
are approximately the same (± 2 °C), otherwise adjust charger/relocate temperature
probe as necessary.
C) Set charger voltage to an equalization value of 2.40 V.p.c (129.6 V) at 25 °C (measure
battery case temperature and set charger voltage to 129.6 V plus 0.162 V for every °C
below 25 °C). Never exceed 132.3 V regardless of temperature.
D) Set a charger temperature compensation slope of - 0.003 V.p.c (- 0.162 V) per °C
above 25 °C.
E) Set a charger maximum (ceiling) voltage of 132.3 V (2.45 V.p.c)
F) Set a charger minimum (floor) voltage of 120.9 V (2.24 V.p.c)
