Modern crossover Nissan Murano is a complex engineering structure where the electrical network plays the role of a nervous system. Not only engine starting, but also the correct operation of the multimedia system, climate control and electronic driver assistants depends on the health of the power source. In harsh winter conditions or long periods of parking, the car battery becomes a critical component, the failure of which can leave you stranded.
Owners Nissan Murano often face the need to replace the battery every 3-4 years. This is a normal resource, but it is important to understand that the wrong choice of capacitance or ignoring the polarity can lead to the failure of expensive control units. In this article, we will analyze in detail which battery is suitable for different generations of the model, how to properly replace it without losing settings, and what nuances need to be taken into account during maintenance.
Features of the Nissan Murano electrical system
Cars Nissan Murano the second (Z51) and third (Z52) generations are equipped with modern generators and charge management systems. This means that the voltage in the on-board network is not a constant value; it varies depending on the load and operating mode of the engine. Standard lead acid batteries may not be able to handle these charge/discharge cycles, which will shorten their service life.
In addition, the car contains many electronic modules that are sensitive to power surges. When disconnecting the terminals on Nissan Murano Often the throttle adaptations are reset or the radio settings are lost. Therefore, the replacement process requires care and knowledge of specific procedures in order to avoid unnecessary problems with the electronics after installing a new battery.
It is important to consider the type of starter and its starting current. In winter in Siberia or the Urals, the load on the starter increases many times due to thickened oil. If you choose a battery, consider not only the capacity, but also the starting current, especially if the temperature in your area drops below -30 degrees Celsius.
Selection criteria and technical parameters
When selecting a replacement, it is necessary to strictly observe the geometric dimensions of the housing, the type of terminals and polarity. For most versions Nissan Murano It is typical to use batteries with reverse polarity (the “+” terminal on the left when looking at the battery), but there are exceptions depending on the year of manufacture and the region of delivery. Incorrect selection will result in the power cables simply not reaching the contacts.
The key parameter is the starting current. For diesel versions it should be significantly higher than for gasoline counterparts. Standard values for V6 petrol engines are between 600 and 700 Amps according to the EN standard. For diesel engines, this figure should be at least 750-800 Amperes to ensure reliable starting in cold weather.
Below is a table with recommended characteristics for various car modifications:
| Generation | Engine | Recommended Capacity (Ah) | Starting current (A) | Size (LxWxH) |
|---|---|---|---|---|
| II (Z51) | 3.5 V6 (Petrol) | 70-80 | 640-720 | 278x175x190 |
| II (Z51) | 3.5 V6 (Hybrid) | 90+ (Starter) | 800+ | 278x175x190 |
| III (Z52) | 3.5 V6 (Petrol) | 75-85 | 680-760 | 278x175x190 |
| III (Z52) | 3.5 V6 (Hybrid) | 95-100 | 850+ | 278x175x190 |
⚠️ Attention! Never install a battery with a smaller capacity than stock, even if it physically fits in the compartment. This will lead to rapid degradation of the battery and the inability to start the engine after a short trip.
When choosing a brand, you should pay attention to production technology. High-quality batteries use calcium or hybrid plates, which are less susceptible to sulfation and self-discharge. Manufacturers such as Exide, Varta, Bosch or Amara, often offer lines specially adapted for Japanese cars with a high-density engine compartment layout.

Self-replacement battery process
Replacing the battery with Nissan Murano is not particularly difficult, but requires a certain set of tools and adherence to a sequence of actions. Before starting work, you need to prepare keys for 10 and 12, as well as lubricant for the terminals. It is better to carry out work in a warm room or during a warm time of day to avoid freezing of the electrolyte in case of accidental discharge.
First you need to turn off the power to the on-board network. It is necessary to disconnect strictly in a certain order: first the negative terminal (minus) is removed, and only then the positive (plus). This rule protects electronic units from short circuits if the key accidentally touches the car body when unscrewing the positive terminal.
☑️ Preparation for replacement
After removing the old battery, you must thoroughly clean the seat and check the condition of the wiring. Oxidized contacts can lead to poor contact and overheating of the terminals. Use a special brush for cleaning, and before installing a new battery, apply a thin layer of special grease or lithol to the terminals to prevent corrosion.
Installing a new battery is done in the reverse order. First, the housing is fixed, then the positive terminal is put on, and lastly, the negative terminal. The terminals must be clamped with force, but without fanaticism, so as not to strip the thread or damage the lead terminal. Make sure that the housing latches are pressed tightly to the bottom of the niche.
⚠️ Attention! If on your Nissan Murano A charge control sensor (IBS) is installed, it must be reset or adapted after replacing the battery. Otherwise, the on-board computer will consider the capacity of the old, worn-out battery, which will lead to incorrect charging mode and rapid failure of the new battery.
What to do with the adaptation of windows and sunroof?
After turning off the power, the “self-timer” and “auto-up” glass functions often stop working. To restore them, lower the window completely, then raise and hold the button up for 3-5 seconds. Repeat for all doors and hatch.
Save your radio station and clock settings before disconnecting the battery by writing them down on paper or taking a photo. This will save you time reconfiguring the multimedia system after installing a new battery.
Saving settings and adapting electronics
One of the main problems when replacing a battery with Nissan Murano is the loss of adaptations of electronic units. The car’s computer remembers the engine operating parameters, adapted to the worn parts, and after resetting the power, it starts working in “basic” mode. This may manifest itself in unstable idle speed or changes in gear shift patterns.
To minimize data loss, experienced professionals use the “feeding” method. To do this, an external power source (charger with voltage maintenance function) is used, which is connected to the OBD connector or directly to the terminals before disconnecting the standard battery. This allows the settings to be saved in the control units' memory.
If you are not using the boost method, a throttle initialization procedure may be required after installing a new battery. This is usually done by turning the ignition on for 10-15 seconds, then starting the engine and idling until it warms up completely. In some cases, a scanner is required to reset errors and adapt.
For owners of hybrid versions Nissan Murano the procedure is even more critical. Here it is necessary to take into account the condition of the traction battery. Disabling the 12-volt battery may cause problems with the hybrid drive control system. In this case, it is strongly recommended to contact specialized services that have the necessary diagnostic equipment.
Using an external power source when replacing the battery is the most reliable way to preserve all multimedia, climate and engine adaptation settings.
Maintenance and service life extension
Even the most expensive and high-quality battery requires regular maintenance. For Nissan Murano It is important to check the electrolyte level in the banks if a serviceable battery model is used. In maintenance-free batteries, monitoring is carried out visually through a status indicator located on the housing cover.
In winter, it is especially important to monitor the electrolyte density and state of charge. Deep discharge of a lead-acid battery can lead to irreversible sulfation of the plates. If the car is parked for a long time, it is recommended to remove the battery and store it in a warm place, recharging it periodically.
- Regularly clean the terminals from oxidation and tighten them.
- Check the operation of the generator for stable voltage in the network.
- Avoid using electrical appliances with the engine turned off.
- Make sure the body is intact and free of cracks.
In addition, it is worth paying attention to the operation of the charging system. If the voltage at the terminals with the engine running exceeds 14.8 Volts or falls below 13.5 Volts, this may indicate a malfunction of the relay regulator or the generator itself. Operating a car with a faulty charging system will quickly kill even a new battery.
How to test a battery with a multimeter?
Connect the multimeter probes to the battery terminals with the engine off. Normal voltage should be in the range of 12.6-12.8 Volts. When the engine is running, the voltage should be 13.8-14.4 Volts.
Market analysis and popular brands
The car battery market offers a wide range of products, but not all of them are suitable for Nissan Murano. Among the most popular brands that have proven themselves among Nissan owners are: Varta (Silver Dynamic and Blue Dynamic series), Bosch (S4 and S5 series), as well as Exide (Premium series). These manufacturers use advanced technology and provide consistent product quality.
It's also worth considering budget options such as Amara or Mutlu. They often offer good value for money, although they may have a slightly shorter lifespan than premium brands. When purchasing, it is important to check the release date of the battery, since even when stored in a warehouse, the battery gradually loses its charge.
For hybrid versions Nissan Murano AGM batteries are best suited. They have higher cycling resistance and are better able to withstand the high load conditions found in hybrid energy recovery systems. Although they cost more, they pay for themselves in increased service life and reliability.
⚠️ Attention! Avoid purchasing batteries manufactured more than 6 months ago. Long-term storage without recharging leads to deep discharge and irreversible changes in the structure of the lead plates, which significantly reduces the battery life.
