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. The higher the CCA, the more power the battery can deliver at 0°F. For trucks in cold climates, we recommend a battery with at least 750 CCA for gas engines and 850 CCA for diesel engines.
Should I choose an AGM or flooded battery for cold weather?
AGM batteries generally outperform flooded batteries in cold weather because they have lower internal resistance and are more resistant to freezing. They also require no maintenance. Flooded batteries are cheaper but may struggle in extreme cold and need periodic water checks. For severe winters, AGM is the better choice.
How does reserve capacity affect cold weather performance?
Reserve capacity (RC) indicates how long a battery can run essential accessories if the alternator fails. In cold weather, a higher RC (120 minutes or more) is beneficial for running heaters, lights, and plows without draining the battery. It also provides a safety margin if the engine is hard to start.
Can I use a battery with lower CCA if I have a block heater?
A block heater reduces the load on the battery by warming the engine, so a lower CCA battery may suffice. However, if you frequently park without plugging in, we still recommend a high-CCA battery. Always match the battery to your worst-case scenario.
How do I maintain my truck battery in winter?
Keep the battery terminals clean and tight. For flooded batteries, check water levels monthly. Ensure the battery is fully charged before a cold snap, as a partially charged battery can freeze. Consider using a battery warmer or maintainer if the truck sits idle for long periods.
