Items Contents Standards Maintenance
Total float
charging
voltage of
battery group
Measure output end
voltage of positive
and negative end of
battery group with
voltage meter.
1. tested data comply with the
data displayed on the
meter and meet the voltage
standard under the
temperature conditions
2. The error of float charge
voltage after temperature
compensation Is ≤ ± 50mV
1. If data attained by testing is varies
from the standard, the tested data
should prevail.
2. For those adjusted by monitor module
and still can’t reach the allowed error
range after module adjustment, repair
is to be applied or send them back to
factory.
