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. 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. 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.

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. 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. Three times greater cycle resistance than standard batteries: highest E4 classification pursuant to EN 50342-1. 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 ...

Halfords Battery Guarantee 

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: 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? Every battery has two main characteristics: Voltage (V) and Capacity (Ah). Voltage of a battery (V)

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 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. 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*Then, you can choose which battery you want according to the manufacturer and price. Make sure you look out for features such as guarantees. 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. 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. 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. 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).
