Always double-check your owner's manual or consult with a trusted mechanic to confirm the correct group size for your specific vehicle.
• Cold Cranking Amps (CCA): CCA is a measure of a battery's ability to start your engine in cold weather. It indicates the number of amps the battery can deliver for 30 seconds at 0°F while maintaining a voltage of at least 7.2 volts. The higher the CCA rating, the better the battery's starting power in cold conditions. For the 2020 Atlas Cross Sport, aim for a battery with a CCA rating of at least 730 CCA to ensure reliable starting performance, even in freezing temperatures.
• Reserve Capacity (RC): RC is the amount of time (in minutes) a fully charged battery can continue to supply power to essential accessories if the alternator fails. A higher RC rating means you'll have more time to reach safety or get to a service station if your alternator quits. A good RC rating for your Atlas Cross Sport battery would be around 120 minutes or more.
• Voltage and Amp-Hour (Ah) Rating: A car battery's voltage is typically 12 volts. The amp-hour (Ah) rating indicates how much charge the battery can store. For the 2020 Atlas Cross Sport, a battery with an Ah rating of around 70-80 Ah should be sufficient. This ensures that the battery can provide enough power to start the engine and run the vehicle's electrical systems.

Why AGM Batteries are Preferred

AGM batteries have become increasingly popular in modern vehicles due to their numerous advantages:

• Maintenance-Free: Unlike traditional flooded batteries, AGM batteries are sealed and don't require you to add water. This makes them incredibly convenient and hassle-free.
• Spill-Proof: The electrolyte in AGM batteries is absorbed into the glass mats, making them spill-proof. This is especially important for vehicles like the Atlas Cross Sport, where the battery may be located inside the passenger compartment.
• Vibration Resistance: AGM batteries are more resistant to vibration than flooded batteries, which is crucial for vehicles that experience rough roads or off-road conditions.
• Longer Lifespan: With proper care and maintenance, AGM batteries can last significantly longer than traditional batteries.
• Better Performance: AGM batteries provide consistent power output and perform better in extreme temperatures, ensuring reliable starting and performance in all conditions.

Common Signs of a Failing Battery

Recognizing the signs of a failing battery can save you from being stranded on the side of the road. Here are some common indicators that your 2020 VW Atlas Cross Sport battery might be on its way out:

• Slow Engine Crank: This is one of the most common signs. If your engine takes longer than usual to start, it could indicate that the battery is losing its ability to provide sufficient power.
• Dim Headlights: If your headlights appear dimmer than usual, especially at idle, it could be a sign that the battery isn't holding a full charge.
• Electrical Issues: Problems with power windows, radio, or other electrical components can also indicate a weak battery.
• Check Engine Light: A failing battery can sometimes trigger the check engine light. Have your vehicle scanned to determine the cause.
• Swollen Battery Case: A bulging or swollen battery case is a sign of internal damage and requires immediate attention.
• Corrosion on Terminals: Corrosion on the battery terminals can impede the flow of electricity. Clean the terminals regularly to ensure a good connection.
• Age of the Battery: Most car batteries last between 3 to 5 years. If your battery is older than that, it's a good idea to have it tested.
