Most brands offer at least a three-year replacement warranty – many offer longer, and usually last a lot longer. Note: All Battery’s come with a warranty – SAVE the receipt in case it requires replacement early.
Read your owner’s manual if you want the exact replacement spec’s, but a good garage, PEP boys, Auto Zone etc, can take your auto model number and find the correct match. There are nine size groups: 65, 75, 24/24F, 34/78, 35, 51R, 47 (H5), 48 (H6), and 49 (H8). Each one of these battery sizes fits different car makes and models. When you shop for a car battery, you can’t just look for the one with the best overall rating; you have to choose one that’s sized to fit your specific vehicle.
You can also choose your battery based on where you live ie: Hot-weather batteries, often labeled “South” or “S,” are designed to endure extreme heat. Cold-weather batteries sometimes labeled “North” or “N” have higher cold-cranking amps (CCA).
Type of driving is also a consideration, for instance Off-roaders should have a leak free battery.
It’s not a good idea to shop by brand name, because many use different manufacturers for different lines and even sizes.
If you do it yourself, bring in your old battery. Many states will have you pay a fee from $5 to $20, known as a “core charge” if you don’t bring an old battery to recycle when you buy your new one. Car batteries are the most recycled item in the world.
