110 BulletBatt Car Battery 12V 80Ah

Product Information

For example : If a light bulb used only 1 ampere in an hour then a 50Ah battery could light up 50 light bulbs for an hour. Alternatively it could power 1 light bulb for 50 hours* The Halfords start/stop batteries come fully charged and ready to fit. Most vehicles require this battery to be registered with the on-board computer system. Therefore, a professional fitting at a Halfords store, autocentre garage or through our Mobile Fitting Service is strongly recommended. Learn more about our Mobile Fitting Services here. Features & Benefits: That is, the same battery could give 4.75A for 20 hours (4.75A x 20 hours = 95Ah c20), 9A for 10 hours (90Ah c10) or 17A for 5 hours. If we did not have the power losses, the battery should have been able to provide 19A for 5 hours (95Ah) or 9.5A for 10 hours (95Ah). In theory, a battery that has 100Ah could give a current intensity of 100 Amps for 1 hour, an intensity of 1 Ampere for 100 hours, or 2 Amps for 50 hours. However, this is not always the case, as the faster a battery discharges, the more power it loses. Therefore, it is common to find batteries that have the following capacity:

Under normal circumstances, there should be no problem installing a larger capacity battery. On the one hand, there is usually not enough space to install a battery with a large starting difference (CCA) and, on the other, by starting with a greater capacity (Ah) and starting force (CCA), we will increase the battery's durability. , since both parameters degrade over time. You'll hear more about Cold Cranking Amps (CCA) during the winter because it's a measure of a battery's ability to start an engine in cold temperatures. Voltage: As the resistance of what we have connected to the battery is fixed, the higher voltage we have, the more current we can provide. Or put another way, the voltage will determine the current intensity and the higher the voltage, the more intensity we will give.

The average car battery will have an Ah rating somewhere around 50Ah. The 50Ah means that it can push 12 volts out at a rate of 50 amperes in an hour. Your car uses the battery for 2 main purposes (1) the Engine (2) the Electrics such as lights, wipers, satellite navigation, stereo and so on.

For example, Varta for the same size has a battery of 70Ah, another of 74Ah and another of 77Ah. The lowest range is the 70Ah and the highest range is the 77Ah. In these cases, the manufacturer always recommends installing the highest-end (77Ah), especially if the car has a large number of electronic components. In a car, everything that is connected to the battery is prepared to operate at a voltage of 12V. What would happen, therefore, if we could connect a 24V battery or 2 12V batteries in series? After all that has been seen, the answer is simple: if we double the voltage, the current intensity would also increase twice and we would run the risk of burning or damaging everything that is connected to the battery. On the other hand, the capacity of a battery, which is measured in Ah, represents the amount of electricity that a battery can provide. The more capacity (Ah) a battery has, the more electricity it can provide.

We have a range of Varta batteries that are perfect to be used in a wide variety of engine powered vehicles and appliances, from cars and motorcycles to caravans and marine vehicles. With a warranty included with all of our Varta batteries, you can buy your Varta battery from Battery2U in complete confidence. The engine size is primary. A larger engine uses a larger starter motor and needs more battery power to turn it over first thing of a cold morning. Other factors include the number of cylinders the engine has, each of which needs converted energy to create a spark for combustion. With the car electrics – most modern cars have sat-nav and a fairly good stereo. 20 years ago this would not have been the case. Additions such as a powerful stereo were usually added later and sat nav’s didn’t even exist. In doing so the driver 20 years ago would probably not have found his or her battery going flat prematurely because the rest of the vehicle had less electronics on-board. It represents the maximum current a battery can deliver for 30 seconds at -17.8°C (0°F) while maintaining a voltage above a specified threshold. The car battery shown above has 800 CCA. This figure is crucial in colder climates, because lower temperatures can reduce a battery's ability to deliver power effectively.

The Halfords AGM115 Start/Stop 12V Car Battery 5 Year Guarantee is required for vehicles with start/stop technology and/or regenerative braking. The AGM (absorbed glass mat) technology allows up to 360,000 engine starts with start/stop functions. And this is where we can find the problem: if the equipment is faulty, has a ground problem or a short (connection of positive and negative), the battery with greater capacity will provide more intensity than a normal one and could damage part of the electronics ( although electronic systems are usually protected by fuses, precisely to avoid these situations).

What isn't covered by the guarantee? 

Use our ‘find the right battery for your car’ tool to find the correct size of battery. You can do this by entering your number plate, or manually entering the details of your car. Although this is not always the case, because the battery design can be different, a battery with a higher capacity will also have a higher CCA, which could be said to be the maximum intensity it can provide in an instant. That does not mean that he is able to provide it in all situations, only when the team needs it. Likewise, if the battery were to discharge, the current intensity would decrease and the engine would not be able to start, some circuits would not receive enough energy to function correctly, etc ...
