Does it matter what size car battery you use?

Car Battery Sizes Do Matter When it comes to car batteries, size matters. The size of your car battery will make a huge difference in the functionality of your car. A small two-door car is much different from a large work truck, and each vehicle requires a different level of power to turn the engine.

Can you put the wrong size battery in a car?

Just as with any part or accessory, using the wrong size battery can lead to a host of problems. While it isn’t always necessary to use the OEM brand, you should always replace your battery with the size and output that the manufacturer recommends.

Does my car need a specific battery?

Are All Car Batteries the Same? No. Car batteries differ in multiple ways to work with different vehicle’s specifications, and they are generally year, make, model-specific. This battery starts your car, and it also provides the power necessary to run the radio, lights, and other electrical components in your car.

What happens if my car battery is too small?

(CA) is the amount of amps that a 12-volt battery can produce for 30 seconds at 32° F (0°C) while maintaining at least 1.2 volts per cell (7.2 volts for a 12-volt battery). In other words, CCA/cold-cranking amps determine how much power you need to start your engine. There is no such thing as too much CCA.

What happens if I connect the car battery wrong?

When the jumper cables are incorrectly connected, the polarity of the electrical system on the vehicle with the dead battery will be reversed for a few seconds. This can irreparably damage many of the sensitive electronic components that are common on today’s vehicles, such as on-board computers and electronic sensors.

Will a higher amp battery damage my car?

As several people have stated, no, a larger battery will not harm your alternator (or other electrical components), provided that it is putting out the correct voltage.

Can any car battery fit any car?

There is no “one-size-fits-all” battery suitable for every car. The battery type, physical size, terminal configuration, and cold cranking amps (CCA) or amp-hour (Ah) rating are all important factors that ensure the proper fit and function of a battery.
