The VARTA Professional Deep Cycle AGM draws on the very best battery technology currently available, namely AGM technology. The battery acid is held in a glass mat, with the open structure of the glass mat and the small spacing between the electrodes resulting in a good discharging capacity and high resistance to knocks and shocks. Together with the battery’s excellent cyclic stability, this means the battery will last for a long time. It is securely sealed and is therefore 100% leak-proof. All of these traits make it a reliable partner away from campsites and moorings too.
