Can I use a car battery with lower amps?

Nothing really, unless the new battery is much lower in capacity than the original. You’re talking about CCA or cold cranking amperage, which is how much current can be drawn from the battery to start the engine.

Can I use a battery with lower ah?

CAN I SUBSTITUTE A LOWER AMP HOUR (AH) BATTERY WITH A HIGHER ONE? As long as the battery that you are substituting is the same voltage, you can use a higher capacity (higher Ah) battery than the original one. … You must also keep in mind that the charge time for a higher Ah battery will be longer than a lower Ah battery.

Do amps matter on car battery?

Overall, the amp hour (ah) rating does not matter much as long as you do not use accessories with the engine off. The main thing you need to worry about is your alternator. You can watch the voltage to determine if the alternator is able to keep up.

Can I use a battery with lower cold cranking amps?

Replacement batteries should equal or exceed the OE battery in ratings. Replacing a battery with a battery that has a lower CCA than the original equipment may result in poor performance.

Can we use 35ah battery instead of 45ah?

The only difference between the two is that the 40 AH will hold a charge a little longer than the 35 AH because the plates have a slightly larger surface area. The power will still be the same because they have the same voltage. … The 40 AH batteries are physically larger than the 35 AH batteries.

Is higher Ah battery better?

The higher amp hours of the battery and the higher AH of the cell are the same thing. … The batteries with higher amp hours deliver more power and more performance, allowing the battery to work for a longer time on a full charge as compared to the cells with lower amp hours.

Is a higher Ah car battery better?

The Ampere-hour rating will tell you for how long the battery be able to provide current of the particular amperage. Higher the Ah rating, more powerful the battery.

How many amps should car battery have?

An average car battery has a capacity of around 48 amp hours which means that, fully charged, it delivers 1 amp for 48 hours, 2 amps for 24 hours, 8 amps for 6 hours and so on.

What happens if the amps are too high?

A higher voltage than a device is designed for will most likely blow up some components, but amperage is derived from how much current is actually drawn, based on the device’s resistance, so having “too much” is not a problem and will do no harm.

How many cranking amps do I need to start a car?

How many Cold Cranking Amps (CCA) do I need for my car? 400 to 500 CCA will typically jump start any vehicle, including large pickup trucks and SUVs. A small car battery can be boosted with as little as 150 CCA while large SUVs and trucks will require 400 to 500 CCA.

What happens if you use a lower CCA battery?

Low CCA ratings on a battery can essentially starve your start up equipment of the current it needs during the engine start process. Electric motors starved of current = heat and extra stress on the parts. This can lead to reduced lifespan of the parts.

Can I install a battery with higher cranking amps?

Yes as long as it is of the same group size. Most new car don;t give you the room to put a larger battery in. … Batteries with higher CCA ratings also tend to be larger. They will still work in your car but may not fit in the battery tray.

How many cold cranking amps should my battery have?

A battery should be big enough to allow reliable cold starting. The standard recommendation is a battery with at least one Cold Cranking Amp (CCA) for every cubic inch of engine displacement (two for diesels).

Can I damage my car using the wrong battery?

Yes, wrong car battery size will eventually damage your alternator. … A small battery will ruin the alternator and make it fail soon enough if you keep using it for short, frequent trips. Small alternators usually depend on the battery to provide power.

What does 35ah mean on a battery?

35 ampere hour is a ‘Standard’ unit of measure for batteries. It means that this battery will deliver 35 amperes at a nominal 12 VDC over a 20 hour period. Then the battery will be “dead” and require recharging. If you draw more amperage, than the standard, you get less than ’35 Ah’ of power.

Can the wrong battery damage the alternator?

A dead battery doesn’t have any effect on alternator while a broken alternator brings down the battery very quickly. A dead battery doesn’t have any effect on alternator…… Dead battery puts more stress to the alternator as it draws more power out of it.
