Battery Basics
The battery is a key part of your 2015 Nissan Altima. It gives power to start the engine and run electrical parts. Knowing battery basics helps you pick the right one. This keeps your car running well and avoids unexpected stops.
Car batteries come in different types and sizes. Each type suits different needs. Understanding battery specs is important to match your car’s demands. This section breaks down battery types and key specs for your Altima.
Battery Types
Most car batteries are lead-acid types. They store energy using lead plates and acid. Two main kinds are flooded and AGM batteries. Flooded batteries hold liquid acid inside. AGM batteries keep acid in glass mats. AGM batteries last longer and handle vibrations better. Flooded batteries cost less but need more care. Choose the type that fits your budget and use.
Key Battery Specifications
Battery size is shown by group numbers like 35 or 24. Your 2015 Nissan Altima uses group size 35 batteries. This size fits the battery tray and holds enough power. Cold Cranking Amps (CCA) show how well a battery starts the car in cold. Higher CCA means better cold starts. Reserve Capacity (RC) tells how long a battery runs without engine power. Pick a battery with enough CCA and RC for your car. Check the battery voltage is 12 volts, standard for most cars.

Assessing Power And Capacity
Power is key for a car battery. Check the Cold Cranking Amps (CCA) to see how well it starts the engine in cold weather. The 2015 Altima needs around 600 CCA for best results. Also, look at the battery’s reserve capacity. This shows how long the battery can run if the alternator stops working.
Brand And Warranty Considerations

Cleaning Terminals
Dirty terminals cause poor electrical contact. Use a mix of baking soda and water for cleaning. Apply gently with a brush to remove corrosion. Dry the terminals before reconnecting the cables.
Extending Battery Life
Turn off lights and accessories when the engine is off. Avoid short trips that do not charge the battery fully. Keep the battery secure to prevent damage from vibrations. Store your car in a cool, dry place to reduce battery wear.

Troubleshooting Battery Issues
Troubleshooting battery issues in a 2015 Nissan Altima is important to keep your car running smoothly. A car battery can fail at any time. Knowing how to spot problems early helps you avoid getting stuck. This section explains common battery problems, signs of a failing battery, and when to seek professional help.
Common Battery Problems
Corrosion on battery terminals is a frequent issue. It blocks the flow of electricity. Loose or damaged cables can cause starting problems. A battery that is old may not hold a charge well. Extreme temperatures also affect battery performance. Cold weather slows the chemical reaction inside the battery. Heat causes the battery fluid to evaporate faster. These factors shorten battery life.
Signs Of A Failing Battery
The engine may turn over slowly or not start at all. Dim headlights or electrical issues can signal battery trouble. Warning lights on the dashboard often appear. Strange clicking sounds when you turn the key are common. A swollen or leaking battery case shows damage. If your car needs frequent jump-starts, the battery is weak. Pay attention to these signs to avoid sudden failure.
When To Seek Professional Help
Call a mechanic if the car won’t start after several tries. If you see fluid leaking from the battery, get help quickly. Strange smells like rotten eggs indicate a battery problem. Testing the battery with proper tools confirms its condition. Professionals can clean terminals, check connections, and test charging systems. Early service saves money and prevents breakdowns on the road.
