How to choose a battery for your car?Find the correct battery size and type compatible with your car's model and engine requirementsFind the minimum cold cranking amperage for your carConsider whether you prefer a maintenance-free batteryCheck the warranty coverageLook for a reputable brand that meets industry standards for quality and performance.
You can also use your current battery as a reference for what size to select. Another thing you need to consider is your vehicle's Cold Cranking Amperage (CCA). This is the minimum amount of power your vehicle needs to start. If you choose a battery below your vehicle's CCA, you'll have trouble getting out of your driveway.
It's important to choose a battery with the longest free-replacement period you can get. A battery's warranty is measured in two figures: the free replacement period and the prorated period—which allows only partial reimbursement. A code of 24/84, for example, indicates a free replacement period of 24 months and a prorated warranty of 84 months.
Car batteries are categorized by size, determined by the Battery Council International (BCI) Group size. This system ensures you can easily identify the correct battery size for your vehicle. Since car and truck batteries vary in shape and size, it's crucial to select one that fits your specific make and model.
If you choose a battery below your vehicle's CCA, you'll have trouble getting out of your driveway. You can find your vehicle's CCA on your existing battery or in your owner's manual. We have a wide selection of car batteries on NAPAcanada.com and in our stores.
Absorbent glass mat (AGM) batteries have quickly become the norm for most modern cars. They use similar chemistry as SLAs but are more durable and are claimed to stand up to more charge cycles. Gel-cell batteries are best for deep discharging but may have problems in extreme hot or cold.
Refer to your vehicle's owner's manual for the required specifications. Use reputable online resources to look up the minimum CCA for your vehicle. It's perfectly fine to choose a battery with a higher CCA rating than required, as it can improve performance, especially in extreme conditions.
