16-24 ELECTRICAL SYSTEM
Remove the battery (see Battery Removal).
Do refresh charge by following method according to the
battery terminal voltage.
This battery is sealed type. Charge with current and
time as stated below.
Terminal Voltage: 12.0 12.7 V
Standard Charge: 0.9 A × 5 10 h (see following chart)
If possible, do not quick charge. If quick charge is
done unavoidably, do standard charge later on.
Terminal Voltage: 12 V or lower
Battery Mate 150-9
OptiMate PRO 4-S/PRO S/PRO2
If the above chargers are not available, use equivalent
Increase the charging voltage to a maximum voltage of
25 V if the battery will not accept current initially. Charge
for no more than 5 minutes at the increased voltage then
check if the battery is drawing current. If the battery
will accept current decrease the voltage and charge by
the standard charging method described on the battery
case. If the battery will not accept current after 5 min-
utes, replace the battery.

Determine the battery condition after refresh charge.
Determine the condition of the battery left for 30 minutes
after completion of the charge by measuring the terminal
voltage according to the table below.
12.8 V or higher
12.0 lower than 12.8 V
lower than 12.0 V
4.5 A × 1 h
0.6 A × 20 h
Charge insufficient → Recharge
Unserviceable → Replace
