Can I use a different size battery in my car?

Getting more capacity will likely be a heavier expensive but will usually work fine. Not using the original battery brand, on the other hand, is completely fine as long as it has the same size and output recommended by the manufacturer.

What happens if you put the wrong size battery in a car?

Manufacturers precisely match their alternators and batteries to the vehicle’s power requirements. A mismatched battery/alternator combo could cause your alternator to overheat and shorten its life.

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 a battery be too powerful for a car?

Installing a larger-capacity battery changes the currents, which could lead to spikes and surges that may damage the on-board computer or fuse panel. You have a lower chance of damaging the computer, but with alternator failure, damage is still a possibility. The fuse panel likely will receive most of the damage.

Can I use a battery with higher cranking amps?

A higher CCA is fine, provided the battery fits, has the terminals on the correct side, and has at least the minimum CCA recommended by the manufacturer of the vehicle.

What does group size on a battery mean?

Car and Truck Battery Group Size

This refers to the battery size that will best fit the physical dimensions, terminal locations and type required for your vehicle. … Group size is typically based on your vehicle’s make, model and engine type.

Does a bigger car battery mean more power?

No, it doesn’t increase engine power in the slightest. It will generally waste a bit more engine power, though. It will draw more charging current from the alternator (increasing engine load), and the additional vehicle weight due to the larger battery adds a bit more load.

What car uses a Group 35 battery?

The Group-35 Battery is also called Q85, and can also work for Group-24; it is just 1-inch less wide. It is often found in Japanese Cars and Trucks from Toyota, Nissan, Mitsubishi, Subaru, Acura, and in some older American Cars.

Are more cranking amps better?

In general, for both CCA and RC, the higher the number the better. However, if you live in a cold climate, the CCA rating should be an important consideration in choosing a battery. Conversely, if you live in a high heat climate, you don’t need as much CCA.

Can a battery have too many cold cranking amps?

In general, one can always exceed the CCA spec. You probably do it on a warm day, with a charged battery. Having more potential current available will not hurt the car’s electrical system.

Are most car batteries interchangeable?

No. Car batteries differ in multiple ways to work with different vehicle’s specifications, and they are generally year, make, model-specific. Many car batteries do have one important similarity in how they work.
