7-3. Determining Battery Charging Current
1 Battery Charging Chart Chart
Find battery cold crank amp (CCA)
rating on battery. Use CCA rating
on chart to find charge current set-
ting for battery.
EXAMPLE: If battery CCA rating is
500, charging current from chart is
100 amperes.
Do not exceed charging current
found on chart. For longer battery
life, use lowest charge rate
possible.
