A car battery is the most important ingredient to offer the desired power supply to start and run the car. The battery offers the needed electricity supply that keeps all electronic components in the car working properly and seamlessly. The battery stores the power in the form of chemical energy and later converts it into electrical power to deliver the desired voltage to the car so that it can ignite the engine. The battery also stabilizes the voltage and power supply to keep your car running on the road.
Car Battery Power Capacity
A Battery power capacity represents the amount of power generated as a result of the underlying electrochemical reaction to run the car. If we measure the car battery in terms of the total number of electrons then it will become difficult to keep track so, for convenience, the car battery power is measured on an ampere per hour basis.
Amp per hour means that if the battery has a capacity of 1 amp per hour, then it will give a continuous power of 1 ampere to the attached load for 1 hour, or 2 amp for half hour, or one-third ampere for 3 straight hours, and so on. Ideally, the battery should be giving this amp-per-hour ratio power until it gets completely discharged and is unable to offer more power. But the reality does not coincide with their ideal ratio. The batteries working in real conditions undergo many factors that affect their performance which is why they can't generate power in this ideal linear manner.
This is so because, at a high current level, the battery generates more heat which affects the internal resistance of the battery. This change in internal resistance can affect the chemical reaction taking place inside the battery which is the reason that battery can discharge sooner than it is ideally meant to. This is why batteries do not follow the linear amp-to-hour ratio.
Some manufacturers also share the derated amp-to-hour ratio to give a real estimate to the customers. The car battery power capacity can also differ for different companies and sizes of the battery. Generally, the car power capacity is 70 amp per hour at 3.5A of power.
Car Battery Voltage
The car battery voltage represents the electric potential the battery holds to provide power to run the car. Usually, the cars are equipped with a 12-volt battery. It doesn’t mean the battery has only 12 volts. In reality, the stored voltage ranges from 12.6 to 14.4 in the battery.
You will be surprised to know that the voltage level varies when the car is not used (that is the engine is off) versus when you are running the car (the engine is working). For a 100% charged car battery with an off-engine, the battery voltage should be 12.6. This voltage which is checked when the car is at rest is referred to as the resting voltage.
When the engine starts and the car hits the road, the voltage fluctuates from 13.5 to 14.5. The alternator is the device that boosts the voltage inside the battery because it is recharging the battery alongside. To understand it in a much better way you should know how the voltage in the battery works. You might be aware that the battery stores the electric charge to generate power.
When the car is started, the stored electric energy in the battery is converted into mechanical energy that ignites the engine to start the car.
Once the engine starts, the alternator generates an electric current which gets over the starter energy from the battery.
During a drive, these 2 phenomena keep on occurring continuously where the starter converts electric energy into mechanical and the alternator recharges the battery and generates an alternate electric current.
If the voltage reading of a car is fluctuating significantly then it means that the alternator or the battery has malfunctioned.
Remember adequate voltage is required to start a car. The ideal voltage to start a car is 12.6 with the engine turned off. The car can be ignited even at 12.4. But below 12.2 volts (while the engine is off) the car won't even ignite and fails to hold the charge.
Car Battery Price
Investing in a worthy car battery lets you enjoy the battery for an extended time. Car batteries are usually expensive. If you take proper maintenance measures then you can enjoy these expensive batteries for many years to come. The cost of car batteries in general ranges from 60$ to 300$. This is why you should invest in a good battery that belongs to a well-reputed brand and whose specifications meet your requirements.
You might be getting confused to see this massive fluctuation between car battery prices. With different companies, features, life spans, and types of batteries the price of batteries fluctuates. Many factors are responsible for this difference in battery prices. Some of the most prominent factors are listed below:
Size of the Battery: The standard size of the battery comes in a group of 24, 65, and 75. Any battery larger than this standard size becomes more expensive because of the larger size.
Technology: a battery can use varying technologies that dictate the working of a battery. The lead-acid batteries are the most cost-effective ones but their life span is short and they can have trouble performing during extreme weather conditions. The AGM (absorbent glass mat) batteries are better in power supply, life span, and stability and are pricier. Then comes gel batteries which are similar in performance to AGM batteries.
Warranty: The car batteries come with warranties that secure users against the product. The warranty amount and terms of warranty fluctuate with the battery model, price of the battery, and other such factors. Or in other words, a battery with a good warranty comes at an expensive price.
Performance in Cold Weather: The batteries also have a measure named cold cranking amps that measure how well the driver has driven the car during cold temperatures. The batteries with high cold cranking ratings are comparatively expensive.
