What happens if you use the wrong size car battery?
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.
Can you use a different size battery in your car?
Different Battery Capacity
Getting more capacity will likely be a heavier expensive but will usually work fine. What is this? 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.
Can I use a battery with higher cranking amps?
More significant considerations are whether the battery fits into the battery tray. Larger CCA rated batteries may be in different size groups. But if you are in the same size group, with suitable connections (posts) then using a higher CCA battery will do no harm.
Can I put a bigger CCA battery in my car?
It is widely believed that the higher the CCA rating, the better the battery will be for your car. It is still possible to use them in your car, but they may not fit in the battery tray. Batteries with a higher CCA can be more reliable and last longer in general.
Will a car start with the wrong battery?
Selecting the wrong battery may also cause the start-stop system to fail. As a result, the engine is rarely or never switched off when the vehicle is at a standstill (e.g. at a traffic light). An incorrect battery can cause a number of various functional failures.
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.
Is 600 cold cranking amps enough?
For an average-size car (this includes compact SUVs to light trucks), a 400-600 CCA jump starter should be enough. A larger truck may need more amps, maybe around 1000 CCA. The amps needed to jump-start a car will be lower than the car battery CCA.
How many CCA do I need for a V8?
A rule of thumb says a vehicle’s battery should have a CCA rating equal to or greater than engine displacement in cubic inches. A battery with a 280 CCA rating would be more than adequate for a 135 cubic inch four-cylinder engine but not big enough for a 350 cubic inch V8.
Does the CCA of a battery matter?
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.
What happens if I put a lower CCA battery in my car?
If your battery has a CCA rating which is too low, the motor won’t receive the current it needs during the start up process. This can cause heat and additional stress on the parts of the motor as the electric motor will be starved of current.
