Signs of a Failing Battery
If your 2019 Nissan Altima is experiencing battery issues, it’s crucial to recognize the signs of a failing battery.
1. Sudden, Slower Start
A noticeable slowing down in your car’s starting cadence, especially in colder temperatures, could indicate a failing battery. If this occurs unexpectedly, it’s essential to have your battery tested promptly.
2. Headlights and Power, But No Start
Having operational lights and accessories, but encountering a click or buzz when trying to start the car, is another sign of a potential battery problem. While the battery may have enough power for lights, it might not provide sufficient amperage for starting the engine.
3. No Radio Functionality
If your radio doesn’t turn on when the ignition is in the ON position, it could be a sign of a weak battery charge. Pay attention to any flickering or dimming of electronic devices before starting your vehicle.
4. Swollen Battery Size
Inspecting the physical condition of your battery is essential. A swollen or fat battery indicates overcharging, likely caused by a faulty voltage regulator. This can lead to irreversible damage and a need for immediate replacement.
5. Odd Smell from the Battery
An unusual smell, particularly a rotten eggs scent, signals potential battery failure. This smell indicates gas venting and the release of sulfuric acid, posing a threat to other engine components. Swift battery replacement is recommended.
6. Aging Battery
As batteries age, their performance declines. The average lifespan of a car battery is four to six years. At the four-year mark, it’s advisable to have a technician assess the battery’s charge to prevent unexpected issues.
7. Check Engine Light Flashing
While a flashing check engine light often signals serious engine problems, it could also be related to a failing battery. Seeking a free diagnosis at your local AutoZone store can help identify the issue.
8. Vehicle Starts, Then Dies Immediately
An unusual scenario where the vehicle starts but dies immediately can be attributed to battery failure affecting signals to the Engine Control Unit (ECU). Conducting a simple battery check is the initial step in troubleshooting this issue.
Choosing the Right Replacement Battery
To address these battery issues, it’s crucial to choose the right replacement battery for your 2019 Nissan Altima.
