Battery terminal torque requirements, Table 1 – C&D Technologies 41-6965 Condensed User Manual
Page 4
The following maintenance schedule should
be followed:
Quarterly
•
Check pilot units temperature at the
negative terminal.
•
Measure and record the system float
charging voltage.
•
Measure and record the individual units float
charging voltage.
Semi Annually
•
Repeat the quarterly checks.
•
Optionally perform a 10 second high rate
(e.g. 100 ampere) load test on the individual
units.
•
Optionally perform an impedance or
conductance test for the purpose of trending
battery over time.
Annually
•
Repeat the semi annual checks.
•
Retorque all inter unit connecting hardware per
table 1.
•
Perform inter unit connector resistance
checks.
IX. PERFORMANCE TESTS
The battery system should be given a capacity
discharge test at acceptance when new and
biannually thereafter. When the capacity declines
to 85% of rating the battery should be capacity
tested annually.
The load current used for the capacity test should be
derated for testing temperatures below 75ºF.
