Infiniti recommends consulting the owner’s manual or contacting a dealership for battery specifications. -
Alternative views:
Some owners prefer to replace batteries only at dealerships for convenience to avoid fitting issues. Alternatively, others may opt for generic batteries, which tend to be more cost-effective. This choice can lead to mixed reviews, as some believe generic options may not provide the same longevity or performance. It is important to weigh these perspectives and choose based on personal preference and experience.
How Do CR 2032 and CR 2025 Batteries Differ in Size and Function?
CR 2032 and CR 2025 batteries differ primarily in their thickness, capacity, and suitable applications.
The dimensions of the two batteries vary significantly:
– Size: The CR 2032 battery has a diameter of 20 mm and a thickness of 3.2 mm. In contrast, the CR 2025 battery has the same diameter of 20 mm but is thinner at 2.5 mm. This difference in thickness affects their fit in devices.
– Capacity: The CR 2032 typically offers a higher capacity, around 220 mAh, compared to the CR 2025, which usually provides about 170 mAh. The higher capacity of the CR 2032 allows it to supply power for a longer duration.
– Functionality: Both batteries are lithium coin cells and are used in small electronic devices. The CR 2032 is commonly found in devices that require longer-lasting power, such as watches, fitness trackers, and medical devices. The CR 2025 is often used in devices where space is a constraint, like remote controls and smaller electronic gadgets.
– Interchangeability: Although the CR 2032 and CR 2025 batteries may look similar, they are not universally interchangeable. The thickness difference means that using a CR 2032 in a device designed for a CR 2025 may result in a poor fit, while the reverse may cause insufficient power delivery.
Understanding these differences helps users select the correct battery for their specific needs.
How Can I Identify the Correct Battery for My Specific Infiniti Key Fob Model?
To identify the correct battery for your specific Infiniti key fob model, you need to check the key fob’s specifications and choose between common battery types like CR2025 or CR2032.

Battery Types and Specifications:
Battery types for Infiniti key fobs primarily include CR2032 and CR2025. The CR2032 battery measures 20mm in diameter and 3.2mm in thickness, while the CR2025 is thinner at 2.5mm. It is crucial to check your specific key fob model to ensure compatibility with the chosen battery. -
Tools Required for Opening the Fob:
To replace your key fob battery, you will need a flat-head screwdriver. This tool allows you to gently pry apart the fob without causing damage. Some users might prefer plastic opening tools to avoid scratching or damaging the key fob’s surface. -
Attention to Polarity During Replacement:
When inserting the new battery, pay close attention to the battery’s polarity. The positive side (usually marked with a “+” symbol) must face the correct direction as indicated in the battery compartment. Incorrect installation can prevent the key fob from functioning properly. -
Model-Specific Considerations:
Different Infiniti models may have unique fob designs or battery requirements. Consult your owner’s manual for specific instructions or visual guidance. Resources such as the Infiniti website or dealership can provide relevant information specific to your model. -
Common Troubleshooting Tips:
If your key fob does not work after a battery replacement, first confirm that the battery is inserted correctly. If issues persist, check for corrosion on the battery contacts. If corrosion is present, clean the contacts with a small amount of vinegar or rubbing alcohol on a cotton swab. Additionally, if the fob still does not function, it may require reprogramming, which usually involves a visit to a dealership.
Following these steps will ensure a successful battery replacement in your Infiniti key fob.
Why Might I Prefer a CR 2032 Battery Over a CR 2025 for My Key Fob?
You might prefer a CR 2032 battery over a CR 2025 for your key fob due to its higher capacity. The CR 2032 battery typically has a capacity of around 220 mAh (milliamp-hours), while the CR 2025 generally has a capacity of about 150 mAh. This means the CR 2032 can power your device longer before needing replacement.
According to the International Electrotechnical Commission (IEC), these two batteries are defined as coin cell batteries with varying heights and capacities (IEC standard 60086). The “CR” designation indicates that they are lithium batteries, which provide higher energy density compared to alkaline batteries.
The preference for a CR 2032 battery can stem from several reasons. First, its larger capacity allows your key fob to perform better over an extended period. Additionally, some electronic devices, such as key fobs, may require a specific voltage and current output, which the CR 2032 can provide more consistently due to its larger size and capacity.
Technical terms are often used to describe battery specifications. For example, “mAh” measures a battery’s energy capacity. Higher mAh values mean more stored energy, which results in longer operational times. Additionally, voltage refers to the electrical potential, and both battery types typically provide 3 volts.
The underlying reasons for choosing one battery over the other can include your usage patterns. For example, if you frequently use your key fob or if it runs additional features like remote start, the CR 2032 may be more suitable due to its extended life. In contrast, if the key fob serves a more limited purpose, then a CR 2025 might suffice.
You should also consider environmental factors that might affect battery performance. Cold temperatures can reduce battery life. If you live in a geographic area with extreme weather conditions, such as very low temperatures, a battery with a higher capacity, like the CR 2032, can ensure reliable performance.
What Warning Signs Indicate That My Infiniti Key Fob Battery Requires Replacement?
The warning signs that indicate your Infiniti key fob battery requires replacement include decreased range, a blinking light, and difficulty unlocking or starting the vehicle.
- Decreased Range
- Blinking Light
- Difficulty Unlocking or Starting the Vehicle
These warning signs suggest that the battery may be losing its charge, requiring prompt attention to ensure proper operation of your key fob.
-
Decreased Range: Decreased range occurs when the key fob fails to operate from a distance. This indicates that the battery may be weak. A fully functioning key fob should work from several feet away. A lack of responsiveness at a distance suggests that you may need a battery replacement.
-
Blinking Light: A blinking light on the key fob is a clear indicator that the battery is low. When you press a button, the light should illuminate steadily. If it blinks or does not light up at all, it often means the battery is close to failure.
-
Difficulty Unlocking or Starting the Vehicle: Difficulty in unlocking doors or starting the engine can signal battery issues. If you find that you often have to press the fob button multiple times or get very close to the vehicle, it is a sign that the battery is losing its charge. Regular use should require only a single press from a normal distance.
The battery in your key fob is crucial for its functionality. Recognizing these signs can help prevent inconveniences when accessing or starting your vehicle.
