If the battery is only mildly discharged, the current consumed by the battery during recharge is determined by the battery itself. The larger battery has more capacity in the first place, so its voltage will drop less than a smaller battery, but it’s also capable of accepting a faster charge.
Can a car battery be smaller than original?
Also, an undersized battery may not have enough juice to power your car’s accessories, especially while your vehicle is turned off. Even just listening to the radio for an extended period may cause your battery to go dead.

Does it matter what size battery I put in my car?
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.

What happens if you put a larger battery in your car?
Larger batteries have more reserve capacity. This gives you more time to run accessories like the stereo or lights without the battery running down to the point where it will no longer start the engine.
Is it OK to use a bigger car battery?
When you use a larger battery, your car’s electrical systems don’t automatically start pulling more current simply because it’s available. The current draw will remain the same. Because of this, a larger battery will not deplete faster than it’s smaller counterpart.
How do I know what size battery to get?
Your car’s battery group size can be found in the battery section of the owner’s manual. If you no longer have access to your original owner’s manual, you may also consult the reference guides provided by battery retailers to determine the appropriate battery group size for your car.
Does a bigger car battery mean more power?
The problem in most cases is that the terminals will contact the hood and short out the battery or the physical dimensions just will not work. Battery physical size does not mean that the battery has more power or longevity.
What is the most common car battery size?
In general, these more-common battery group sizes are 24, 24F, 25, 34, 35, 51, 51R, 52, 58, 58R, 59, and 65. Helpful Hint: Some vehicles can handle a larger battery than was originally installed. A physically larger battery usually has more power and reserve time than a smaller battery.
Does idling car drain battery?
Over time, idling can cause your head gasket, spark plugs, or cylinder rings to deteriorate and stop working. Drains car battery. Idling does not allow your battery to charge and causes it to strain.
Can I swap batteries between cars?
so, it’s not surprising that some people believe car batteries are universal and completely interchangeable too. This is not the case. It is important to ensure that your car has the right battery for its needs.
How can I test my alternator?

- Get a multimeter.
- Set your multimeter to DCV (DC Volts) above 15.
- Make sure your alternator’s positive and negative terminals are clean.
- Put the multimeter’s black cable to the negative terminal and the red cable to the positive terminal.
- Look for an ideal alternator reading of around 12.6.
What to do after installing a new battery?
After placing the new battery in the battery tray, secure it with the hold-down or clamping device. This helps to reduce vibration—one of the key contributing factors in premature car battery failure. 11. Check the battery cables for corrosion, and, if necessary, clean them.
How long should I let my car run after installing a new battery?
Unhook the clamps in the reverse order of how you put them on. Be sure to drive your car for about 30 minutes before stopping again so the battery can continue to charge. Otherwise, you might need another jump start.
When you buy a new battery is it fully charged?
When you buy a car battery, it typically comes sufficiently charged to start your vehicle, to around 90% of capacity or so. It isn’t required to charge a car battery before its first use.
How do I know if my car battery is compatible?
Look under the specifications section in your owner’s manual. The battery group size as well as other pertinent battery information will be in the specs. Step 3: Search online for the group size. Use an online resource to determine a battery group size for your car.
Is a bigger battery better?
However, some may assume that it is referring to a battery that is physically bigger in size. If all specifications of the battery are the same, there is essentially no advantage of a physically bigger battery. In fact, it is better that the battery is smaller to suit the limited space available in a car.
How do I match my alternator to my battery?
Your alternator should be capable of delivering rated output equal to the maximum acceptance rate of your house battery bank. In other words, the alternator’s rating should be equal to 25 percent (lead acid) 30 percent (gel) or 45 percent (AGM) of your total battery capacity.
How do I determine the size of my alternator?
To figure out how much capacity or amperage the alternator must deliver, determine how much extra power the audio system demands on top of the current system. For example, if you installed a 2,000-watt amp, assuming a nominal voltage of 13.5V, you’d add roughly 150 amps of demand to the electrical system.
Does a bad battery affect the alternator?
A bad battery won’t damage the alternator, but a bad alternator can damage a battery. The car battery simply isn’t made to deliver electrical energy for extended periods, so both components need to be functioning optimally.
