Battery Types and Specifications

The 2010 Nissan Murano typically uses a Group Size 35 battery. However, it's always recommended to verify the specific battery requirements for your vehicle based on its trim level and any aftermarket accessories installed. The Group Size 35 designation refers to the battery's physical dimensions, terminal placement, and general performance characteristics as defined by the Battery Council International (BCI).

Key specifications to consider when selecting a replacement battery include:

Voltage: 12 volts is the standard for automotive batteries in the Murano.
Cold Cranking Amps (CCA): CCA represents the battery's ability to deliver a high current burst at 0°F (-18°C) for 30 seconds while maintaining a voltage of 7.2 volts or higher. A higher CCA rating is generally desirable, especially in colder climates, as it indicates a stronger starting capability. The recommended CCA for a 2010 Murano is typically around 640-700 CCA, but consult your owner's manual or a trusted auto parts retailer for the precise specification.
Reserve Capacity (RC): RC indicates the number of minutes a fully charged battery can continuously deliver 25 amps at 80°F (27°C) before the voltage drops below 10.5 volts. A higher RC rating signifies the battery's ability to power the vehicle's electrical systems for a longer duration if the alternator fails. This is particularly important for vehicles with numerous electrical accessories.
Ampere-Hour (Ah): Ah is a measure of the battery's energy storage capacity. It represents the amount of current (in amps) that a battery can deliver for a specific number of hours. While not always prominently displayed, a higher Ah rating generally correlates with longer battery life and improved performance.

There are several types of lead-acid batteries commonly available, each with its own advantages and disadvantages:

Flooded Lead-Acid Batteries

These are the traditional and most common type of automotive battery. They contain liquid electrolyte that freely flows within the battery's casing. They are generally the least expensive option, but require periodic maintenance, such as checking and topping off the electrolyte levels with distilled water. Flooded batteries are more susceptible to damage from vibration and spillage if not properly secured.

Absorbent Glass Mat (AGM) Batteries

AGM batteries are a type of valve-regulated lead-acid (VRLA) battery. In AGM batteries, the electrolyte is absorbed into a fiberglass mat separating the lead plates. This design offers several advantages over flooded batteries, including:

Spill-proof: The absorbed electrolyte eliminates the risk of spillage, making them safer and more versatile in mounting orientations.
Maintenance-free: AGM batteries are sealed and do not require topping off with water.
Vibration resistance: The solid construction makes them more resistant to vibration and shock.
Faster charging: AGM batteries can typically accept a higher charge rate compared to flooded batteries.
Longer lifespan: Under comparable operating conditions, AGM batteries generally have a longer lifespan than flooded batteries.

AGM batteries are a popular upgrade choice for the 2010 Murano, particularly for vehicles equipped with a lot of aftermarket electronics or those frequently used in harsh environments. However, they are typically more expensive than flooded batteries.

Enhanced Flooded Batteries (EFB)

EFB batteries represent an intermediate technology between flooded and AGM batteries. They feature enhanced construction and materials to improve their performance and lifespan compared to standard flooded batteries. EFB batteries often incorporate features such as thicker plates, improved separators, and enhanced electrolyte additives. They offer better cycling performance and vibration resistance than flooded batteries but are generally less expensive than AGM batteries. EFB batteries can be a good compromise for vehicles that require more robust performance than a standard flooded battery but don't necessarily need the full capabilities of an AGM battery.

Battery Installation and Maintenance

Replacing the battery in a 2010 Nissan Murano is a relatively straightforward process that most DIY enthusiasts can handle. However, it's essential to follow safety precautions and proper procedures to avoid damage to the vehicle or injury. Here's a general overview of the steps involved:

Gather necessary tools: You'll need a wrench (typically 10mm or 13mm) to loosen the battery terminals and hold-down clamp, a battery terminal cleaner, a wire brush, and potentially a memory saver device to prevent data loss from the vehicle's electronic control units (ECUs).
Disconnect the old battery: Always disconnect the negative (-) terminal first, followed by the positive (+) terminal. This prevents accidental short circuits. Be careful not to touch the wrench to any metal parts of the vehicle while disconnecting the terminals.
Remove the battery hold-down: This clamp secures the battery in its tray. The design varies depending on the specific model year.
Lift out the old battery: Be mindful of the battery's weight and lift with your legs, not your back.
Clean the battery terminals and tray: Use a battery terminal cleaner and wire brush to remove any corrosion from the terminals and the battery tray. This ensures a good electrical connection.
Install the new battery: Place the new battery in the tray, ensuring it's oriented correctly.
Secure the battery hold-down: Tighten the hold-down clamp to prevent the battery from moving around.
Connect the new battery terminals: Connect the positive (+) terminal first, followed by the negative (-) terminal. Ensure the connections are tight and secure.
Verify proper operation: Start the vehicle to ensure the new battery is functioning correctly.

Regular maintenance is crucial for extending the life of your battery. Here are some key practices:

Keep terminals clean: Periodically inspect the battery terminals for corrosion and clean them as needed.
Avoid deep discharge: Excessive discharge can significantly shorten the battery's lifespan. Avoid leaving headlights or accessories on for extended periods when the engine is off.
Proper storage: If the vehicle will be stored for an extended period, disconnect the battery or use a battery maintainer to prevent it from discharging.
Regular testing: Have the battery tested periodically, especially as it ages, to assess its health and performance. Many auto parts stores offer free battery testing services.

Factors Affecting Battery Life

Several factors can influence the lifespan of a battery in the 2010 Nissan Murano:

Climate: Extreme temperatures, both hot and cold, can significantly reduce battery life. Heat accelerates corrosion and electrolyte evaporation, while cold temperatures reduce the battery's chemical reaction rate.
Driving habits: Frequent short trips can prevent the battery from fully charging, leading to sulfation and reduced capacity.
Electrical load: High electrical loads, such as running numerous accessories or a powerful aftermarket sound system, can strain the battery and shorten its lifespan.
Vehicle's charging system: A malfunctioning alternator can overcharge or undercharge the battery, both of which can damage it.
Battery quality: Higher-quality batteries generally last longer and perform better than lower-quality batteries.
