Battery in Nissan Murano Z51 - a unit that often becomes a headache for owners after 5-7 years of operation. The problem is especially acute in winter, when cold starts require maximum performance from the battery. But even if the car starts with a bang, this does not guarantee that the battery is not on the verge: modern crossovers with their on-board electronics and systems Start-Stop impose strict requirements on the condition of the battery.

In this article we will figure out what kind of battery is needed for Murano Z51 (including versions with VQ35DE and hybrid systems), how to choose the right one among dozens of brands, and what to do to avoid running into a fake. And also - why after replacing the battery the throttle adaptation may be reset and how to avoid this. If you have already encountered a dead battery or just want to prepare for winter, read on.

Battery specifications for Nissan Murano Z51

First thing you need to know: Murano Z51 (2015–2023) is equipped with batteries with reverse polarity ("0" or R+), where the “plus” is on the right. This is critical as incorrect connections can damage the electronics. Standard parameters for most trim levels:

• 🔋 Capacity: 70–80 Ah (for versions with Start-Stop - up to 90 Ah).
• ⚡ Starting current: 600–800 A (EN) or 700–900 A (SAE). For cold regions, it is better to take extra.
• 📏 Dimensions: 278×175×190 mm (length×width×height). Height deviation of ±5 mm is acceptable, but no more.
• 🔌 Terminal type: standard “European” (diameter “+” - 19.5 mm, “−” - 17.9 mm).

For hybrid versions Murano Hybrid the requirements are stricter: here you need a battery with improved cycle resistance (for example, AGM or EFB). The fact is that the energy recovery system constantly charges/discharges the battery, and a regular “acid tank” will fail in 1–2 years. Also often used in hybrids 12V auxiliary battery for powering the on-board network - its parameters are indicated in the service documentation.

⚠️ Attention: If on your Murano Z51 system installed Intelligent Key (keyless entry), after disconnecting the battery, the keys may need to be resynchronized. To do this, insert the key into the ignition switch and turn it to position ON and wait 10 seconds.

For hybrids, the clear choice is AGM, since they can withstand up to 300 deep discharge cycles versus 50–80 for conventional batteries.

Step-by-step instructions for replacing the battery

Replacing the battery with Murano Z51 does not require special skills, but there are nuances that even experienced drivers miss. For example, an incorrect shutdown may result in a factory reset. BCM (body control module) or operating errors Xtronic CVT.

Here is the algorithm of actions:

1. 🔑 Preparation: Turn off the engine, remove the key from the ignition, open the hood and lock it.
2. 🔧 Removing terminals: First disconnect the negative terminal (black wire), then the positive terminal (red). This minimizes the risk of short circuit.
3. 🔩 Removing the fastening: unscrew the nut on the clamping bar (10 wrench) and remove the old battery.
4. 🧹 Cleaning: remove oxides from the terminals and pad (you can use a soda solution or a special cleaner).
5. 🔄 Installing a new battery: install the battery, secure the bracket, connect the terminals in the reverse order (“+” first, then “−”).

Are the terminals tightened (tightening torque 5–7 Nm)|

Does the alarm and central locking work?

Are there any errors on the dashboard (for example, P1614 — immobilizer failure)|

Have the radio and climate control settings been reset?

Check the voltage at the terminals (should be 12.6–12.8 V with the engine off) -->

If after replacement the light on the dashboard lights up Check Engine, don't panic: this is often due to system recalibration. To reset the error, you can disconnect the battery for 10 minutes or use a diagnostic scanner (for example, Launch X431).

⚠️ Attention: On Murano Z51 with the system ProPILOT Assist Cameras and radars may need to be retrained after replacing the battery. To do this, you need to drive 5–10 km on a straight road at a speed of 40–60 km/h.

Common mistakes when choosing and replacing batteries

Even experienced car owners sometimes make mistakes that lead to rapid battery failure or problems with electronics. Here are the most common:

• 🔋 Wrong capacity: installing a 60 Ah battery instead of the recommended 70–80 Ah leads to constant undercharging and sulfation of the plates.
• ❄️ Ignoring climate: in northern regions, a battery with a starting current of 600 A may not cope with frosts below −20°C.
• 🔌 Poor terminal contact: oxides or weak tightening lead to voltage drops and malfunctions ECU.
• 🔄 Lack of adaptation: after replacement, the on-board computer settings are not reset, which leads to incorrect charge readings.

Another typical mistake is buying a battery “for growth”. For example, installing a 90 Ah battery in a version without Start-Stop may lead to undercharging, as the generator Murano Z51 (140–150 A) is not designed for such loads. Also, don’t skimp on brands: cheap batteries (for example, Titan or Zver) often have underestimated real parameters and fail after 1–2 years.

What happens if the polarity is reversed?

If connected incorrectly (“+” to “ground”), at best the fuses will burn out, at worst it will fail. ECU, control unit CVT or multimedia system. On Murano Z51 the module is especially vulnerable I-Key, the repair of which costs 30,000–50,000 rubles.

How to extend battery life: tips for Murano Z51

Average battery life for Murano Z51 - 4–6 years, but with proper use it can be increased to 7–8 years. Here's what really works:

• 🚗 Regular trips: If the car sits idle for more than 2 weeks, the battery is discharged. It is optimal to drive at least 30 km per week.
• 🔌 Charging in winter: in frosts below −15°C, the battery voltage drops by 20–30%. Use automatic storage (For example, Ctek MXS 5.0) to maintain charge.
• 💡 Disabling consumers: Before parking for a long time, turn off seat heating, multimedia and other devices that consume power in standby mode.
• 🔧 Generator check: if the voltage at the terminals is lower when the engine is running 13.8 V, the generator is not charging the battery.

For hybrid versions Murano it is critical to monitor the condition auxiliary battery (usually located under the trunk floor). Its lifespan is 3–5 years, and if it fails, the car may not start, despite a serviceable main battery.

Battery diagnostics: when is it time to change?

A battery rarely fails suddenly; it is usually preceded by “symptoms” that are easy to notice:

• 🔊 Slow engine start: The starter turns sluggishly, especially in the morning.
• 💡 Dim headlights: When the engine is idling, the headlights shine weaker than usual.
• ⚠️ Errors on the panel: warnings appear like Low Battery or Service Required.
• 🔋 Fast discharge: After parking overnight, the voltage drops below 12.4 V.

For accurate diagnosis you can use:

• 📊 Multimeter: measure the voltage with the engine turned off (the norm is 12.6–12.8 V). If below 12.2 V - the battery is low.
• 🔧 Load fork: The load test will show the actual capacity. Drawdown below 9 V - a sign of wear.
• 💻 Diagnostic scanner: some errors (eg P0562 - low on-board voltage) directly indicate problems with the battery.

If the battery “dies” suddenly, check not only it, but also generator, fuses (especially F37 And F38 in the block under the hood) and mass on the body. Often the problem lies in oxidized contacts or a broken negative wire.

What to do if the battery runs out on the road?

The situation when Murano refuses to start in the middle of the highway, familiar to many. Here's what you can do:

1. 🚗 Lighting up: connect the wires to the donor (observe the polarity!), start its engine and let it run for 5–10 minutes. Then try to start Murano. If it doesn’t work, check the contacts.
2. 🔋 Booster (starting device): connect NOCO GB40 or similar booster to the terminals and start the engine. It's safer than lighting a cigarette.
3. 🔧 On-site replacement: If you have a spare battery, replace it following the instructions above. The main thing is not to forget to reset the errors with the scanner.

If none of the methods worked, check:

• 🔑 Immobilizer: Sometimes after a complete discharge the battery blocks the start. The keys need to be retrained.
• 🔌 Fuses: check in the block under the hood F10 (10 A) and F20 (15 A) - they are responsible for the ignition circuits.
• 🚨 Alarm: some systems (for example, Pandora) block the starter when the battery is discharged.

⚠️ Attention: On Murano Z51 with CVT You cannot tow the car for a push start - this can damage the variator. The only safe way is to light a cigarette or use a booster.

FAQ: Frequently asked questions about the battery Nissan Murano Z51

Is it possible to install a battery with a larger capacity than the manufacturer recommends?

Yes, but with reservations. For example, instead of 70 Ah, you can put 80 Ah if the generator can cope with recharging. However, for versions without Start-Stop A capacity higher than 80 Ah is impractical - the battery will constantly be undercharged. Also make sure that the new battery physically fits in the designated space (height and width).

What kind of battery is installed on Murano Z51 from the factory?

Original battery from Nissan has an article number 28501-4M00B (for petrol versions) or 28501-4M01B (for hybrids). This is a battery with a capacity of 70 Ah, a starting current of 640 A (EN), manufactured GS Yuasa or Panasonic. However, original batteries are often more expensive than analogues with similar characteristics.

Is it necessary to “train” the on-board computer after replacing the battery?

Yes, on Murano Z51 After replacing the battery, it is recommended to reset the adaptation ECU And TCM (transmission control module). To do this:

1. Disconnect the negative terminal for 15 minutes.
2. Plug it back in and start the engine.
3. Let it idle for 5-10 minutes, then drive 10-15 km with smooth acceleration.

This will help the computer “retrain” for the new battery.

Why does the multimedia system not work after replacing the battery?

On Murano Z51 multimedia complex NissanConnect may require code entry after power failure. The code is usually found in the service book or on a sticker in the glove compartment. If there is no code, contact your dealer - he can generate it using the VIN. Also check the fuse F36 (15 A) in the cabin unit.

Can lithium batteries be used on Murano Z51?

Theoretically yes, but in practice this is fraught with problems. Lithium batteries (for example, Braille B14115) is lighter and more powerful, but:

• Requires a special charger.
• May conflict with the system Start-Stop (not all models support BMS - battery management system).
• They cost 2–3 times more than lead-acid ones.

If you decide to use lithium, choose models with built-in BMS and tension 12.8 V (For example, Antigravity AG-801).
