Can I Put a Smaller Battery in My Car? Placing a battery with smaller dimensions than the battery box can be done as long as you can still secure it safely and tightly in place. However, you’ll want to make sure that the voltage is the same and that CCA’s are equal to or exceed the manufacturer’s recommended number.
What happens if you put the wrong size battery in your car?
Yes, wrong car battery size will eventually damage your alternator. … Small cells will make the alternator work eventually to supply the flow of energy. However, bigger batteries also require a lot of power from your alternator. The alternator has to work hard to charge these bigger batteries.
Will a smaller battery hurt my car?
Smaller battery size for your car may eventually result in a loss of power. You can feel that the power supply for your vehicle is not enough. … A battery that is too small will prematurely wear out, if it cant sustain the cranking current to start the car..
What happens if I put a lower CCA battery in my car?
Technically a car can use a battery with a lower CCA, but it can damage your engine. Your ignition system may also suffer. In some cases, using a lower CCA battery can lead to starters or ignition coils failing.
Will a higher amp battery damage my 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 it bad to leave your car running for 30 minutes?

Can a battery be too powerful for a 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. And the higher the cold cranking amp rating of the battery, the better it is for your car. …
Does a bigger battery mean more power?
However, in larger battery packs, the physical arrangement and extra number of cells will often mean that they will give a bit more power because you’re more likely to have one or two cells that give a bit higher voltage (because all batteries are slightly different and there’s some natural variation) and the cells won …
