Frequently Asked Questions
What does CCA mean and why is it important for cold weather?
CCA stands for Cold Cranking Amps, a rating that measures a battery’s ability to start an engine in cold temperatures. A higher CCA means more starting power when the oil is thick and the chemical reactions inside the battery slow down. For cold climates, we recommend a battery with at least 700 CCA for gasoline trucks and 800+ CCA for diesels.
Is AGM better than flooded for cold weather?
AGM (Absorbed Glass Mat) batteries generally outperform flooded batteries in cold weather because they have lower internal resistance, which allows more current to flow during startup. They are also spill-proof and more vibration-resistant. However, they cost more. For extreme cold, AGM is usually the better choice.
Can I use a deep-cycle battery as a starting battery in winter?
While deep-cycle batteries can start an engine, they typically have lower CCA than dedicated starting batteries. In cold weather, a deep-cycle battery may struggle to deliver enough power for a reliable start. It is best to use a starting battery for cranking and a deep-cycle for accessories, or a dual-purpose AGM.
How do I maintain my truck battery in cold weather?
Keep the battery terminals clean and tight. Ensure the battery is fully charged before a cold snap, as a discharged battery can freeze. For flooded batteries, check the electrolyte level and top off with distilled water. Consider using a battery warmer or maintainer if you park outside in extreme cold.
What is the best battery for a diesel truck in cold weather?
Diesel trucks require higher CCA due to higher compression. Look for batteries with at least 850 CCA, preferably AGM. The Odyssey 34-PC1500T (850 CCA) or DieHard Advanced Gold (930 CCA) are excellent choices. Many diesel owners also use dual battery setups for redundancy.
