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.

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. As with most things, it’s always worth shopping around to make sure you’re getting the best product, at the best price. Choosing the right battery for your car will help ensure your car performs as it should as well as minimise the risk of costly breakdowns. We constantly price match our batteries but from time to time you may find a like for like battery at a lower price. If this is the case please let us know as we will do our very best to beatthat price. The AGM car battery EK800 is ideal for vehicles with a modern start-stop and regenerative braking system and is approved by the car manufacturer. The acid is leak-proof bound in a glass fleece and the unique carbon additive makes this battery extremely powerful and durable. Replace Varta F21 Silver Dynamic AGM. Benefits of the Exide EK800 Car Battery: In short, if we install a higher capacity battery, we will increase battery life, improve starting and, in addition, we will be able to use the electronic equipment of our vehicle for a longer time. However, what happens if we don't have a space to install a larger battery? 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.Then, you can choose which battery you want according to the manufacturer and price. Make sure you look out for features such as guarantees. Three times greater cycle resistance than standard batteries: highest E4 classification pursuant to EN 50342-1. 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. For these cases, manufacturers usually manufacture batteries of different benefits for the same size. The most basic range usually has less ah and the highest range contains the highest performance, both in amp hours and starting capacity.

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. 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. 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.If you start to notice your car’s engine isn’t quite behaving properly – for example, it doesn’t always start first time, you can hear it whirring but it doesn’t actually start or you can’t turn it on at all, it’s likely time to change your battery. 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. 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. 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:

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). 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 ... Therefore, answering the initial question, if we replace a car battery with a higher capacity one, we will be able to leave the elements that depend on the battery in operation for a longer time. In addition, with the same consumption the higher capacity battery will discharge less, which in the long run will result in a longer battery life. Is there a problem if we install a higher capacity battery?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. Every battery has two main characteristics: Voltage (V) and Capacity (Ah). Voltage of a battery (V) 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. 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). Resistance: It is the resistance offered by what we connect to the battery. If we connected a direct cable from one terminal to another, the battery would give its maximum current intensity. For this reason, it is very dangerous to connect any current conducting element between the two battery terminals. Be careful, therefore, with connecting a direct cable, putting something metallic between the two terminals, or even spilling water on the battery.
