Hyundai Venue: Charging System / Battery. Repair procedures
In general, vehicle battery charging system has three forms.
| 1. |
Constant current charge: The battery voltage gradually rises by charging
with setting a constant current. If charging current and time are not
managed correctly, the battery is over-charged, therefore charging should
be stopped after confirming the completion of charging.
| – |
General charge: Charging the battery for a long time with low
current
|
| – |
Quick charge: Charging the battery for a short time with high
current
|
|
| 2. |
Constant voltage charge: The battery charge current is gradually reduced
by charging with setting a constant voltage.
|
| 3. |
Constant current-Constant voltage charge: Charging with constant current
and voltage to protect the battery damage
| (1) |
Initial Stage: Charging with constant current
|
| (2) |
Last Stage: Charging with constant voltage
|
• |

|
|
Battery Tray
| 1. |
Remove the battery.
(Refer to "Removal")
|
| 2. |
Remove the air cleaner assembly.
(Refer to Engine Mechanical System - "Air Cleaner")
|
| 3. |
Remove the ECM.
(Refer to Engine Control System - "ECM")
|
| 4. |
Remove the installation bolt (A) and then remove the battery (+) terminal
bracket.
|
Battery (+) terminal bracket installation bolt :
8.0 - 10.0 N.m (0.8 - 1.0 kgf.m, 5.9 - 7.4 lb-ft)
|
|
| 5. |
Remove the battery tray after loosening the bolts (A).
|
Battery tray installation bolts :
8.8 - 13.7 N.m (0.9 - 1.4 kgf.m, 6.5 - 10.1 Ib-ft)
|
|
| 1. |
Install in the reverse order of removal.
| •
|
When installing the battery, fix the mounting bracket
on the tray correctly.
|
|
| •
|
After disconnecting then reconnecting the battery negative
cable, reset some parts that require the reset procedures.
(Refer to Body Electrical System - "General Information")

|
|
| Vehicle parasitic current
inspection |
| 1. |
Turn the all electric devices OFF, and then turn the ignition switch
OFF.
|
| 2. |
Close all doors except the engine hood, and then lock all doors.
| (1) |
Disconnect the hood switch connector.
|
| (3) |
Close the doors or remove the door switches.
|
|
| 3. |
Wait a few minutes until the vehicle’s electrical systems go to sleep
mode.
| •
|
For an accurate measurement of a vehicle parasitic current,
all electriacl systems should go to sleep mode. (It
takes at least one hour or at most one day.) However,
an approximate vehicle parasitic current can be measured
after 10-20 minutes.
|
|
|
| 4. |
Connect an ammeter in series between the battery (-) terminal and the
ground cable, and then disconnect the clamp from the battery (-) terminal
slowly.
| •
|
Be careful that the lead wires of an ammeter do not
come off from the battery (-) terminal and the ground
cable to prevent the battery from being reset. In case
the battery is reset, connect the battery cable again,
and then start the engine or turn the ignition switch
ON for more than 10 sec. Repeat the procedure from No.
1.
|
|
| a. |
Connect a jump cable between the battery (-) terminal and the
ground cable.
|
| b. |
Disconnect the ground cable from the battery (-) terminal.
|
| c. |
Connect an ammeter between the battery (-) terminal and the
ground cable.
|
| d. |
After disconnecting the jump cable, read the current value of
the ammeter.
|
|
| 5. |
Read the current value of the ammeter.
| • |
If the parasitic current is over the limit value, search for
abnormal circuit by removing a fuse one by one and checking
the parasitic current.
|
| • |
Reconnect the suspected parasitic current draw circuit fuse
only and search for suspected unit by removing a compoconnected
with the circuit one by one until the parasitic draw drops below
limit value.
|
|
Limit value (after 10-20 min.) : Below 50mA
|
|
| 1. |
Make sure the ignition switch and all accessories are in the OFF position.
|
| 2. |
Disconnect the battery cables (negative first).
|
| 3. |
Remove the battery from the vehicle.
| •
|
Care should be taken in the event the battery case is
cracked or leaking, to protect your skin from the electrolyte.
Heavy rubber gloves (not the household type) should
be wore when removing the battery.
|
|
|
| 4. |
Inspect the battery tray for damage caused by the loss of electrolyte.
If acid damage is present, it will be necessary to clean the area with
a solution of clean warm water and baking soda. Scrub the area with
a stiff brush and wipe off with a cloth moistened with baking soda and
water.
|
| 5. |
Clean the top of the battery with the same solution as described above.
|
| 6. |
Inspect the battery case and cover for cracks. If cracks are present,
the battery must be replaced.
|
| 7. |
Clean the battery posts with a suitable battery post tool.
|
| 8. |
Clean the inside surface of the terminal clamps with a suitable battery
cleaning tool. Replace damaged or frayed cables and broken terminal
clamps.
|
| 9. |
Install the battery in the vehicle.
|
| 10. |
Connect the cable terminals to the battery post, making sure tops of
the terminals are flush with the tops of the posts .
|
| 11. |
Tighten the terminal nuts securely.
|
| 12. |
Coat all connections with light mineral grease after tightening.
| •
|
When batteries are being charged, an explosive gas forms
beneath the cover of each cell. Do not smoke near batteries
being charged or which have recently been charged. Do
not break live circuit at the terminals of batteries
being charged.
A spark will occur when the circuit is broken. Keep
open flames away from battery.
