You can use any battery you want temporarily so long as it has a high enough amperage to crank the car over.

.

Hereof, can I use a different car battery?

No Lifer. Any battery will work as long as it has the minimum Cold Cranking Amps needed for your car and will physically fit in your battery tray. If it's too big for the tray you can always mount it in the trunk. My car has the battery mounted in the trunk; stock from the factory like that.

is it OK to put a bigger battery in your 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. When you use a larger battery, your car's electrical systems don't automatically start pulling more current simply because it's available.

Just so, what happens if you put the wrong size battery in your 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.

Does revving the engine charge the battery?

But when your engine turns faster, the engine's alternator also turns faster. That way, all of the alternator's power can be directed to recharging the battery. Once the car starts, you CAN rev it up to charge the battery faster, but the best way to do that is to just drive it.

Will a car battery recharge if you let it sit?

The "self-recharging" features of batteries is most noticeable in a car battery. In some cases you can crank the engine until the battery seems totally dead, then come back an hour later and crank it again. If you let the battery rest for awhile, the hydrogen gas dissipates and the battery "comes back to life".

How many years do car batteries last?

Under these conditions, you can probably expect your car battery life to be about six years. On average, a car battery lasts between two and five years. If you live in the northern United States, your car battery lifespan will be longer, because you're in a cold climate.

Can a car battery be too dead to jump start?

YES, a car battery can get so dead it will not receive a jump start anymore. To cut to the chase, and just before we get to the meaty stuff, a “dead” car battery is an indicator of different factors—and almost always, these occur all at the same time.

How long before car battery dies with radio on?

Still all things taken into account, 4 hours to 40 hours. If I could measure the power drawn by the stereo and knew the battery was new and its specification, we could be pretty accurate. Note that interior lamps can run 10 or 15W so would add significantly to the load if you leave the doors open.

What do I do when my car battery dies?

The most common way to deal with a dead battery is by jump-starting it. All you need to jump-start a car is a set of jumper cables and another car (a good Samaritan) with a functional battery. Keep in mind that you should never try to jump-start a car if its battery is cracked and is visibly leaking acid.

Can the wrong battery damage the alternator?

A battery that simply will not accept charge won't necessarily cause premature failure of the alternator unless it is permanently at a low voltage, in which case see the 'shorted' section above. The alternator damage in this scenario is caused by heat. The insulation on the rotor windings can be damaged.

How do you keep a car battery charged when not in use?

Use an all-weather car cover if you cannot leave your car in a garage. Get the car washed and waxed before placing it in storage. Be sure to fill up the gas tank and add a gas stabilizer if you will be storing the car for more than 30 days. Use a battery tender to avoid having to jump-start the battery.

Can I replace car battery with higher CCA?

Replacing a car battery is not as straightforward as it once was. And the higher the cold cranking amp rating of the battery, the better it is for your car. But, don't get that confused with cranking amps – CA. See, cold, cranking amps – CCA, cranking amps – CA.

Does the size of a car battery matter?

Car battery size refers to the physical dimensions of the battery, and although some battery sizes that will not fit your car may fit the electrical specifications needed to make the car work, they will not fit properly into your battery socket and will probably cause problems if you use them.

What happens if you connect positive to negative on a battery?

Connecting the positive terminal of each battery to the negative terminal of the other battery will result in a huge surge of electrical current between the two batteries. The heat can melt internal and external battery parts, while the pressure from the hydrogen gas can crack the battery casing.

How many amps is needed to jump start a car?

400 amps is probably enough to start most small to midsize CARS and the smallest of SUVs and trucks. To start "bigger" vehicles you will probably need the 1000 amp unit. The battery for your car is picked out by the engineers so it's cold cranking amps (CCA) number is bigger than the needed amps to start the engine.
