If you choose a new battery with a lower RC, it could fail to properly power your car’s critical systems. With more and more cars using computers and battery power for essential systems, RC has become an important battery feature.Īs with CCA, try to match your new battery’s RC with the original battery. Reserve capacity refers to a battery’s ability to keep essential car accessories powered after a vehicle’s alternator fails. As with group size, your current battery’s CCA should be listed somewhere on the battery label.Įach car is engineered with the factory battery CCAs in mind, which is why it’s a good idea to match the CCA of your current battery – rather than attempt to “upgrade” your battery to one with more CCAs, as this can lead to decreased battery life. The higher the CCA, the more powerful the battery. You can also check your owner’s manual, which may list the group size, or try searching Google for your group size based on your vehicle’s make, model, and year.ĬCAs refer to a battery’s ability to turn a cold engine. All batteries should have their group size listed somewhere on the label. In addition to battery dimensions (length, width, and height), terminal location is also critical to proper fit.įortunately, you won’t need to get out the measuring tape to match battery dimensions. If it is too big, it won’t fit in your vehicle. If your replacement battery is too small, it won’t be properly secured. Your car battery rests in a specifically sized battery box.

Lithium-ion : Lithium-ion batteries can be much smaller and lighter than AGM and SLA batteries.It is the most common type of car battery in modern vehicles. This type of battery offers a superior lifespan to standard flooded batteries and can handle large power demands. Battery acid is absorbed in fiberglass mats, which prevents leakage or spillage. Absorbed glass mat : An absorbed glass mat battery is highly vibration-resistant, non-spillable, and maintenance-free.This type of battery is most common in older vehicles (pre-1980). The battery contains liquid battery acid and will require more maintenance than an AGM or lithium-ion battery. Standard flooded lead acid : This is the most common type of car battery.Lithium-ion batteries are also becoming more common for cars.

Standard lead-acid (SLA) and absorbed glass mat (AGM) batteries are the most common. There are a number of different car battery technologies out there. When looking for a new car battery, you should look for a replacement with specs similar to your old battery. There is no one best car battery for every vehicle.
