The EK091 belongs to the Exide EXIDE Start-Stop Auxiliary range. More Exide batteries
Inside the EK091: AGM technology
The EK091 is AGM: the electrolyte is absorbed in glass fibre mats, so it is sealed and spill-proof. It withstands many more cycles than a conventional lead battery, at the cost of being more sensitive to overcharging.
