Buying Guide
Choosing the right battery for your diesel truck can seem complicated. Here are some key things to consider.
- Cold Cranking Amps (CCA): This is crucial for starting your diesel engine in cold weather. The higher the CCA, the better. Make sure the battery meets or exceeds your truck’s requirements.
- Reserve Capacity (RC): This indicates how long the battery can power your vehicle’s electrical system if the alternator fails. A higher RC is better, especially if you have lots of accessories.
- Battery Type: AGM (Absorbent Glass Mat) batteries are typically better than traditional flooded lead-acid batteries. They are more durable, spill-proof, and offer better performance.
- Size and Fit: Ensure the battery fits your truck’s battery tray. Check your owner’s manual for the correct group size.
- Brand Reputation: Stick with reputable brands known for quality and reliability.
- Warranty: A good warranty can save you money and hassle if something goes wrong.
- Consider your Accessories: If you have winches, aftermarket lighting, or a powerful sound system, you’ll need a battery with higher amperage output.
