Inspection [07/2015 - ]: Procedure

ELECTROLYTE SPECIFIC GRAVITY
1. Measure the electrolyte specific gravity using a hydrometer.
  If it is less than the specification, recharge the battery.
  
  See step 5
  
  Battery electrolyte specific gravity
  
  1.22 to 1.29 (20 °C (68 °F))

BATTERY VOLTAGE

Inspect the battery as follows:

Step	Inspection	Results	Action
1	Measure the battery positive voltage.	12 V or more	Go to Step 3.
1	Measure the battery positive voltage.	Less than 12 V	Go to the next step.
2	Quick charge for 30 minutes and recheck voltage.	12 V or more	Go to the next step.
2	Quick charge for 30 minutes and recheck voltage.	Less than 12 V	Replace the battery. Refer to REMOVAL [07/2015 - ]
3	Using the battery load tester, apply load current (see battery load test current) and record battery voltage after 15 seconds. Is voltage more than the specification?	Yes	Normal
3		No	Replace the battery. Refer to REMOVAL [07/2015 - ]

Battery load test current

55D23L (60 A*h/20HR): 180 A

GR35 (60 A*h/20HR): 180 A

N-55 (50 A*h/20HR): 130 A

STANDARD SPECIFICATION

Battery temperature (°C (°F))	Minimum voltage (V)
4 (39)	9.3
10 (50)	9.4
16 (61)	9.5
21 (70)	9.6

PARASITIC DRAW
NOTE:
Operating electrical loads while the parasitic draw is being measured can damage the tester.
1. Verify that the ignition is switched off and all doors, the bonnet and trunk/liftgate are closed.
2. Disconnect the negative battery cable.
  Refer to REMOVAL [07/2015 - ]
3. Connect the tester between the negative battery terminal and negative battery cable.
  HINT:
  - If the battery is not left undisturbed for 10 minutes or more, the tester will indicate a high value (approx. 300 mA).
  - If the push button start or any electrical accessory is operated after the tester is connected, the battery must be left undisturbed for 10 minutes or more from that point.
  - For vehicles with the immobilizer system, the system periodically shifts synchronization of the security indicator light flashing. Therefore, 65 mA (0.1 sec.) current is supplied when the security indicator light is illuminated, and 40 mA (2 sec.) current is supplied when the security indicator light is not illuminated. In addition, the measuring instrument, which shows the average value, indicates around 55 mA.
4. Leave the vehicle electrical system undisturbed for 10 minutes or more, and then measure the parasitic draw.
  - If not within specification, measure the parasitic draw while removing the fuses one by one from the inside of the relay and fuse block and the inside of the fuse block.
  - Inspect and repair wiring harnesses and connectors of the fuse where the current draw has decreased.
