Kia Sportage (5th generation, NQ5): Battery Replacement

The battery is located in the engine bay on the left side of the vehicle (as seen from the driver's seat) and is secured by a lower hold-down bracket. A battery sensor (IBS) is installed next to the negative terminal. It must not be removed from the terminal or damaged. After replacement, some electronics may need to be reset.

Difficulty: Easy Time: 30-40 minutes Steps: 12

Part

№	Part	Alternatives
01	12 V starter battery, about 60-70 Ah, European case size, reverse polarity (positive on the right)with Start-Stop — higher cold-cranking current version, AGM/EFB	Varta, Bosch, Exide, Mutlu

Tools

10 mm socket or wrench (sometimes a 12 mm is needed for the hold-down bracket)
extension with ratchet
terminal cleaning tool (brush or sandpaper)
terminal protective grease
multimeter. Optional: 12 V memory saver that plugs into the cigarette lighter socket

Step by step

12 steps

Park the vehicle on level ground, set the parking brake, turn off the engine, switch off all electrical consumers, and remove the key or move out of the smart key range with the doors locked. Wait 3-5 minutes for the control modules to go to sleep. Write down or photograph the radio, clock and other settings.
Open the hood and, if necessary, remove the plastic cover over the battery (held by latches or clips). Release it carefully without yanking.
Disconnect the negative terminal first: loosen the 10 mm clamp bolt on the terminal or IBS sensor and lift the terminal off the post. Move it aside so that it cannot touch the battery.
Then disconnect the positive terminal: open the protective cap, loosen the 10 mm bolt, and remove the terminal.
Remove the bolt of the lower hold-down bracket (fastener at the base of the battery, 10-12 mm wrench), then remove the bracket or clamp.
Lift out the old battery with both hands by the handle or the case. It is heavy (about 14-18 kg), so keep it upright to avoid spilling electrolyte.
Inspect the battery tray and terminals: remove dirt and corrosion, and if there is electrolyte leakage, wipe it with a baking soda solution and dry it. Make sure the vent tube (if equipped) is intact and connected to the new battery the same way as on the old one.
Set the new battery on the tray, check the polarity (positive on the positive side, same as the old one), and secure it with the bracket. Bracket bolt torque: about 8-12 N·m (6-9 lb-ft). Tighten evenly without skewing it; the battery must not move.
Connect the positive terminal first, then the negative. Terminal torque: about 4-6 N·m (3-4 lb-ft). Do not overtighten, since the lead posts are soft. Coat the terminals with protective grease and fit the cap over the positive terminal.
Check the voltage with a multimeter: with the engine off, a new battery should read about 12.4-12.8 V. Start the engine and confirm 13.8-14.8 V at the terminals (alternator charging).
Put the cover back. Check the operation of the power windows (recalibrate the "auto" function if necessary by holding the switch at its end position), the clock, the radio and the Start-Stop mode. To start the car after the reset, press the brake pedal first, then the start button.
Take the old battery to a recycling center. Do not throw it in the trash.

Common mistakes and warnings

Always start by disconnecting the negative terminal and finish by connecting the negative terminal, so that you do not short the positive to the body with a wrench
Do not remove the IBS sensor from the negative terminal and do not replace its wiring
If charging fault codes appear after replacement or Start-Stop does not work, a 20-30 minute drive often helps: the system learns and accounts for the capacity of the new battery
If the faults remain, check the terminal tightness and have the sensor condition checked at a repair shop
