Internal resistance, conductive and instant loading experiment instruments.
1.2
Monthly Maintenance
—
Keep the battery-room clean.
—
Measure and record the ambient temperature of the battery-room.
—
Check each battery’s cleanliness, check damage and trace of overheating on
the terminal, container and lid.
—
Measure and record the total voltage and floating current of the battery
system.
1.3
Quarterly Maintenance
—
Repeat monthly inspection.
—
Measure and record floating voltage of every on-line battery. If there is more
than one battery with voltage of less than 13.1V after temperature adjustment,
the batteries have to go through equalization charged. If the problem persists
after adopting the above-mentioned measure, the batteries will require yearly
maintenance or even three years’ maintenance. If all methods are ineffective,
please contact the manufacturer.
1.4
Yearly Maintenance
—
Repeat quarterly maintenance and inspection.
—
Check whether the connectors are loose or not annually.
—
Perform a discharge test to check the exact load every year and discharge
30-40% of the rated capacity.
1.5
Three-year Maintenance
—
Perform a capacity test every three years and every year after six years’ of
operation. If the capacity of the battery decreases to lower than 80% of the
rated capacity, the battery should be replaced.
