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. 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. 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? 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.

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*

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). 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.

About Bosch

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. 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.
