16-26 ELECTRICAL SYSTEM
Measure with a digital voltmeter [A] which can be read
to one decimal place voltage.
If the reading is below the specified, refreshing charge is
Battery Terminal Voltage
Remove the battery [A].
Do refresh-charge by following method according to the
battery terminal voltage.
This battery is sealed type. Never remove seal caps
[B] even at charging. Never add water. Charge with
current and time as stated below.
Terminal Voltage: 11.5 ∼ less than 12.6 V
0.9 A × 5 ∼ 10 h (see following chart)
4.0 A × 1.0 h
If possible, do not quick charge. If the quick charge
is done due to unavoidable circumstances, do stan-
dard charge later on.
Terminal Voltage : less than 11.5 V
Charging Method : 0.9 A × 20 h
If the current does not flow when charging, raise the
voltage initially (25 V as maximum), and let down the
voltage to charge when the current starts to flow as a
yardstick. If ammeter shows no change in current after
5 minutes, you need a new battery. The current, if it can
flow into the battery, tends to become excessive. Adjust
the voltage as often as possible to keep the current at
standard value (0.9 A).
