What is the Difference Between Cold Crank Rating and Reserve Rating in Car Batteries in Houston, TX?

September 13, 2018 5:01 am Published by Leave your thoughts

Batteries were first invented in the 19th century and they have been featured heavily in a wide range of commercial, automotive, industrial and residential products and applications ever since. Modern batteries are capable of delivering incredible amounts of energy and are designed for optimum longevity, durability and performance.

Durable, long-lasting batteries are especially important when it comes to automotive applications. Car batteries must deliver consistent performance regardless of extreme weather conditions and other circumstances. You might have heard about cold crank ratings and reserve ratings before, but it’s important that you understand the difference between these two ratings so that you can select the car battery that is best for you.

Cold crank rating vs. reserve rating

The cold crank rating is an indicator of a battery’s ability to start an engine in cold temperatures. This figure is important since car engines are far easier to start when the temperature is warmer than when it is colder.

The cold crank rating specifically indicates the number of amps that a 12-volt battery can maintain for 30 seconds with an environmental temperature of 0°F can deliver at 0°F for 30 seconds while keeping a voltage of at least 7.2v.

Reserve capacity is a measurement of time that references how long a fully-charged battery can deliver 25 amps of current in 80°F temperatures before the battery discharges to 10.5 volts. Reserve rating is an indicator of how a battery will perform over an extended period of use, while cold crank rating demonstrates a battery’s ability to deliver brief, powerful bursts of energy.

Choosing a car battery

The importance of the cold crank rating might seem pretty straightforward, but why is the reserve rating so important for car batteries? Most of the time, your car battery will be used to ignite your engine and then will be charged as your car runs. However, there are some circumstances that might require prolonged battery usage.

Let’s say, for example, that you experience a sudden mechanical issue with your car while you’re driving. You need your battery to power windshield wipers, electronic accessories, headlights and electrical pumps while you await roadside assistance.

It’s important to think about both reserve ratings and cold crank ratings when you’re selecting a battery. If you live in a colder climate, it’s especially important to purchase a battery with a good cold crank rating. If you live in a rural area, pay special attention to reserve ratings so you can power your car’s electrical components in the event that you are stuck roadside for a longer period of time.

The best way to select a good battery is to find a local supplier of car batteries in Houston, TX who can give you some direction and explain the various factors that apply.
