Car batteries are essential for auto maintenance. Make sure to get a battery that's right for your car and that works for you.
Before buying a car battery, check your car's owner's manual or examine the old battery in your car to make sure you buy the right size and type. Most cars use a 12.6 volt lead-acid battery, but others use different voltages and different electric charge methods. Also, check your car's owner's manual to see whether it specifies a recommended number of cold cranking amps (CCA). A battery's CCA tells you how much power it can deliver when it's 0 degrees Fahrenheit outside. Your battery should meet your car's minimum CCA recommendation, but don't go more than 200 amps above that number.
Consider the battery's reserve capacity as well. Reserve capacity is the time in minutes that the battery can deliver 25 amps before dropping below 10.5 volts. The higher the reserve capacity, the better. Finally, consider whether to get a no-maintenance or low-maintenance battery. No-maintenance car batteries never require any maintenance, while low-maintenance batteries require you to replenish the battery water occasionally.
