What is a good CCA for a battery?

Still, it’s good to be aware of your CCA rating, as replacement batteries should equal or exceed the original battery in ratings to avoid poor performance. Typical CCA readings for a car range from 350 to 600A, and higher for trucks.

A higher CCA just creates the ability for the battery to provide more starting amperage; it does not force more power than your starter should consume. More significant considerations are whether the battery fits into the battery tray. Larger CCA rated batteries may be in different size groups.

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.

CCA or Cold Cranking Amps is the maximum current that a new, fully charged, 12V battery can deliver for 30 seconds, with the voltage NOT dropping below 7.2V, at 0°F (-18°C).

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.

Well, that’s still very important, because cold, cranking amps tells you the ability of the battery to do work right now. And the higher the cold cranking amp rating of the battery, the better it is for your 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.

The battery capacity won’t impact it at all except taking longer to charge. The vast majority of the alternators output is directed to running the vehicle and any accessories. The charge rate on any battery is well below what the battery is rated for.

EverStart batteries are available at Walmart and are made by a company that also produces some of the premium brand batteries. These have excellent performance and are very affordable. The amp ratings are perfect for extreme weather and below freezing temperatures. There is no maintenance involved and very easy to use.

5 Signs That Your Car Battery Needs to Be Replaced
Car Struggling to Start. If the vehicle isn’t starting or seems slow to fire up, then it’s often the battery that’s the problem. Flickering/Dimming Lights. Dashboard Warning Light. Electrical Malfunctions. Corrosion.

How many amps do I need to jump start my car? 400 to 600 amps will be more than enough to jump-start any normal, consumer vehicle. Commercial vehicles may require up to 1500 or 2000 amps. Compact and small vehicles can be boosted with as little as 150 amps.

While the required power will vary depending on the type of battery you have, 400 to 600 amps should be enough to start your battery. If your car is relatively small, you might not need more than 150 amps to get your car battery started.

They can be recharged by applying an appropriate voltage to the outside terminals, thereby reversing the chemical reaction inside the cells. For a detailed explanation, see our article on battery theory.

Expert Reply: In order to achieve maximum cranking amps you will want to wire your two 12 volt batteries in parallel (see photo). The output of 12 volts will remain the same but the capacity and cranking amps will become the sum of the two batteries.
