Prolong your car battery’s life by not using the radio, lights, or AC when the car isn’t running. Car battery pricesĬar batteries vary in price based on the type and the size, but you can typically expect to pay between $100 and $300.įor an SLI battery, you’ll usually pay between $100 and $200.įor a sealed battery like an AGM, you’ll usually pay between $200 and $300. If you plan to install the battery yourself, it helps to choose a model with a handle to make lowering it into the tight confines of a car engine a little easier.
Look for a completely sealed battery for the least maintenance necessary.Ĭar batteries can weigh as much as 40 pounds, which can make them difficult to maneuver. The best car battery is relatively maintenance free, which means you don’t need to add liquid to it. For a higher performing battery, opt for one with 2 hours of reserve capacity.
Look for a battery that can supply at least 1½ hours of reserve capacity. Battery reserve capacityĪ battery’s reserve capacity indicates how long it can provide power if you leave the headlights and other accessories on, or if the battery’s charging system fails. For the best results, choose a battery with the highest CCA rating available that fits the car manufacturer’s requirements. The rating indicates the number of amps that a 12-volt battery is able to deliver at 0℉ for 30 seconds while keeping the voltage at a steady 7.2 volts.ĬCA rating is particularly important if you live in a cold climate. Cold cranking amps (CCA)ĬCA measures a battery’s starting power in cold temperatures. Your owner’s manual should list your vehicle’s requirements when it comes to a CA rating, so you can choose the right option for your car. They’re not used as often in cars, though, because the battery can run down fairly quickly, making it difficult to drive long distances.ĬA measures the starting power of a battery. Deep cycle batteriesĭeep cycle batteries deliver power over a more prolonged period of time than SLI batteries. They are a type of lead-acid, rechargeable battery, but can only provide power in quick bursts, such as the few seconds it takes to start the car. Most car batteries are SLI batteries, which help start the car, as well as power the lighting, radio, ignition, and other features. Starting, lighting, and ignition (SLI) batteries AGM batteries provide more power in short bursts than other sealed batteries, so they work well for cars.
Gel cell types work best in deep cycles, and they may have issues in extreme hot or cold, so they’re not the best option for cars. There are two main types of VRLA batteries: gel cell and absorption glass mat (AGM). If the battery goes, it must be replaced. They are completely sealed, though, which means they usually can’t be repaired. VRLA batteries are low maintenance and don’t require adding any water as wet cell batteries do.
