BATTERY INSPECTION [MZI-3.7]
ELECTROLYTE SPECIFIC GRAVITY
1. Measure the electrolyte specific gravity using a hydrometer.
z
If it is less than the specification, recharge the battery. (See
BATTERY RECHARGING [MZI-
3.7]
.)
Battery electrolyte specific gravity [20 C {68 °F}]
1.22-1.29
BATTERY VOLTAGE
1. Inspect the battery as follows:
VOLTAGE SPECIFICATION
Battery load test current
80D26L(55): 195 A
Standard specification
WARNING:
z
Since battery acid is toxic, be careful when handling the battery.
z
Since battery acid is highly corrosive, be careful not to allow it to
contact clothing or the vehicle.
z
In case battery acid contacts skin, eyes, or clothing, flush it
immediately with running water. Especially if the acid gets in the
eyes, flush with water for more than 15 min and get prompt medical
attention.
Step
Inspection
Action
1 Measure the battery positive voltage.
12.4 V or
more
Go to Step 3.
Less than
12.4 V
Go to the
next step.
2 Quick charge for 30 min and recheck voltage.
12.4 V or
more
Go to the
next step.
Less than
12.4 V
Replace the
battery.
3
Using the battery load tester, apply load current (see ) and record battery
voltage after 15 s. Is voltage more than the specification?
Yes
Normal
No
Replace the
battery.
