Monthly Maintenance
—
Keep the battery-room clean.
—
Measure and record the ambient temperature of the battery-room.
—
Check each battery’s cleanness; check damage and overheating trace of 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 more than one
battery’s voltage is lower than 13.1V after temperature adjustment, the
batteries need to be equalization charged. If the problem still exists after
adopting above-mentioned measures, the batteries need yearly maintenance or
even three years’ maintenance. If all methods are ineffective, please contact
us.
1.4
Yearly Maintenance
—
Repeat quarterly maintenance and inspection.
—
Check whether connectors are loose or not every year.
—
Make a discharge test to check with exact load every year, discharge 30-40%
of rated capacity.
1.5
Three-year Maintenance
—
Make a capacity test every three years and every year after six years’
operation. If the capacity of the battery decreases to lower than 80% of rated
capacity, the battery should be replaced.
