Many modern cars now feature an Auxiliary Car Battery which supports the main car battery in its function, or in many cases supports specific electrical systems on board your vehicle. For example, the Renault Twizy features an Exide EK143 battery to run the 12V systems while the main battery pack powers the drive system.
We supply AUX batteries from all major battery manufacturers such as Varta, Yuasa, Enduroline and Exide. We offer next day delivery on all stock items when ordered before 4PM on weekdays. Should you have any technical questions about your aux battery, please feel free to contact us.
