CHARGING
1. Remove the battery from the vehicle.
2. The normal charging current is a value in amperes which is 1/10th of the battery capacity. If the
battery needs to be charged rapidly because of reasons such as time limitations, the maximum charging
current for rapid charging is the battery capacity expressed as an ampere value.
Battery typeCapacity (5-hour rate)Normal charging currentRapid charging current
75D2354 A5.4 A54 A
80D2658 A5.8 A58 A
95D3170 A7.0 A70 A
3. Determine when charging is finished.
DWhen the specific gravity of the battery electrolyte is constantly within 1.250 - 1.290 for a continuous
period of one hour or more
DWhen the voltage per cell during charging is 2.5 - 2.8 V constantly for a continuous period of one hour
or more
Caution
1. The battery plugs should be removed during charging.
2. The battery electrolyte level may rise and overflow from the battery during charging.
3. Explosions may occur if the battery is brought close to naked flames during charging.
4. Be careful to avoid tasks that might produce sparks or other danger while the battery is charging.
5. After charging is complete, replace the battery plugs, pour water over the battery to rinse
away any sulphuric acid, and let the battery stand to dry.
6. Charge the battery in a well-ventilated location.
7. Do not let the battery electrolyte temperature rise above approximately 45
°C (approximately
55
°C during rapid charging).
BATTERY TEST
Test procedure
OK
NG
Replace
Re-test
OK
Normal
(1) Connect a battery tester to the battery.
(2) Apply aloadwith the specified current to the battery.(Refer
to Table 1.)
(3) After measuring the battery voltage after 15 seconds,
remove the loadcurrent.
(4) Compare the measurement value with the specified
minimum voltage.(Refer to Table 2.)
OK:Higher than the minimum voltage
Measure the battery discharge voltage.
OK:12.4 V or more (specific gravity 1.240)NGCharge the battery at 5 A (constant current charging). (Refer
to Table 1.)
(1) Turn on the headlamps for 15 seconds.
(2) Turn off the headlamps and let the battery stand for 2
minutes to allow the battery voltage to stabilise.
(3) Disconnect the battery cables.
