The simple answer is yes. ambient temperature has a significant impact on battery life and performance. Most car batteries use a liquid electrolyte solution to hold a charge, which is affected by hot or cold weather. While it takes extremely low temperatures to freeze a battery, cold reduces the solution’s ability to transfer full power (which is why it can be hard to start a car in winter). There’s a misconception that buying a battery with a higher cca (cold cranking amp) rating will remedy this, but since vehicle computers regulate the amperage required for startup, it actually won’t make any difference.
