In general, a battery with a CCA rating of at least 300 is recommended for most vehicles in moderate climates. However, if you live in a particularly cold climate, you may want to consider a battery with a CCA rating of 400 or higher.
Here are some additional factors to consider when choosing a weather car battery:
* Battery size: Make sure the battery you choose is the correct size for your vehicle. The battery size is typically listed on the battery's label.
* Terminal type: The battery's terminals must match the terminals on your vehicle's battery cable.
* Warranty: Choose a battery with a good warranty. The warranty should cover both defects in materials and workmanship.
By considering these factors, you can choose the right weather car battery for your vehicle and ensure that you're able to start your engine even in the coldest weather.
