Infiniti battery replacement in Al Taawun
An Infiniti takes a Japanese JIS-size battery, usually a D23 on the Q50 and QX50 and a D26 or D31 on the QX60, QX70 and QX80. Most are standard maintenance-free batteries with no coding, so the change is done where the car is parked in Al Taawun in one short visit. The technician tests the battery and alternator free before fitting anything.

Infiniti battery sizes and types
JIS codes read like 80D23L. The first number is a performance rating, the letter and digits give the case, and the last letter gives the terminal side. Saloons such as the Q50 and Q70 usually sit in the D23 case, with some V6 and V8 cars in D26. The QX60 and QX70 usually use D26, and the QX80 with its 5.6 V8 takes a D26 or the longer D31 depending on year. Idle-stop models carry their own codes such as Q-85 or S-95. The technician copies the code from the fitted battery.

Infiniti models we replace batteries for
Tap a model for its battery type, where it sits and what the swap involves.
Infiniti QX80The QX80 usually takes a D26 or D31 JIS battery in a front corner of the engine bay. With a 5.6 V8, rear AC and screens for every row, it should get the highest-rated battery that fits the tray.
Infiniti Q50On the Q50 the battery is at the rear of the engine bay under a cowl cover, usually a D23 size. The 2.0t with idle stop needs a start-stop rated battery, while V6 versions take a standard one.
Infiniti QX60The QX60 usually takes a D26 battery under the bonnet and is a quick swap. As a school-run seven-seater it idles with the AC on a great deal, so capacity matters more than the brand on the label.
Infiniti QX50The newer QX50 with the variable-compression turbo engine has idle stop on many versions and takes an EFB or AGM start-stop battery. The older V6 QX50 uses a standard D23. The technician checks which one you have.
Infiniti Q70The Q70 keeps its battery under the rear cowl cover like the Q50, usually a D23 or D26 depending on engine. It is a large saloon with many comfort modules, so slow window and seat motors are an early hint.
Infiniti QX70The QX70, formerly the FX, usually takes a D26 battery tucked at the back of the engine bay under a cover. Access is tighter than on the QX80 but it is still a front-of-car job done in any bay.
How the battery and charging system work on a Infiniti
Underneath, an Infiniti is Nissan engineering, and the electrical system is refreshingly plain. Most models charge a conventional maintenance-free battery through a current sensor that lets the alternator rest when the battery is full. There is no registration step. The exceptions are the four-cylinder turbo cars: the Q50 2.0t and the QX50 with the variable-compression engine have idle stop on many versions and need a start-stop battery, EFB or AGM. What all Infinitis share is a thirst for standby power, since the Intelligent Key system keeps listening for the fob day and night.
Signs a Infiniti battery is on its way out
- The push-button start lights the dash, the engine gives one click and the cluster dims.
- The door handle buttons stop responding and the car has to be opened with the emergency key blade.
- Cranking sounds slower after a few days parked, and the idle dips when the AC compressor cuts in.
What we watch for when fitting a Infiniti battery
- The cowl cover over the battery on the Q50, Q70 and QX70 is unclipped, never forced; its clips go brittle in the heat, so they are eased out one at a time.
- After reconnection the power windows need their auto-up function reset, and a steering sensor light may need a short drive to clear.
- Idle-stop models get a start-stop rated battery with the same JIS code, not the ordinary battery of the same case size.
- The technician asks where the key is kept, because a fob stored within range of the car keeps the keyless system awake and slowly drains the battery.

Where the battery sits in a Infiniti
Infiniti hides some batteries well. On the Q50, Q70 and QX70 the battery sits at the back of the engine bay, close to the windscreen, under a plastic cowl cover held by clips. It is not visible when the bonnet first goes up, and people sometimes assume it is in the boot. The QX60 and QX80 have it in a front corner in plain view. Either way everything is reached from the front, so the car can stay as it is in a basement bay and the job does not block the aisle.
Infiniti battery help around Al Taawun
Summer is the test for an Infiniti in Al Taawun. Daily highs sit around 42 to 43 C in July and August, and a QX80 left on an open podium deck or along New Al Taawun Road soaks up that heat on top of what a big V8 leaves under the bonnet after a drive. Heat speeds up corrosion inside the battery all season, and the failure usually arrives a month or two later, when the damage is done. Basement parking helps. So does a test in May, while the timing of a replacement is still your choice.
Infiniti battery replacement: FAQs
Is an Infiniti battery the same as the one in the matching Nissan?
Often, yes. The QX80 shares its platform and V8 with the Patrol and the QX60 with the Pathfinder, so case sizes usually match. The technician still reads the code on your battery, since trims and years differ.
Why can't I see the battery when I open the bonnet of my Q50?
It is under a plastic cover at the back of the engine bay, near the base of the windscreen. The cover unclips to reveal the battery and its fuse links. It is not in the boot.
Can leaving the Intelligent Key near the car flatten the battery?
It can contribute. When the fob stays within range, the car keeps waking to talk to it, and that small draw adds up over days of parking. Keep the key a good distance from the car, and have the battery tested if it has gone flat more than once.
How long should the battery in a QX80 last in Sharjah?
Around two to three years is typical in private use here, sometimes less if the car does short trips or sits for long spells. Heat is the main cause, not mileage. A yearly test from the second summer onwards tells you where yours stands.
