The well trusted and top quality Century Deep Cycle Flooded range are constructed with thicker plates, specialist antimonial lead alloys and denser active material to withstand repeated recharge and discharge cycles.

They are suitable for use in engine bays (under the bonnet / hood) but not for internal use in caravans, motorhomes etc. as they will produce gasses while charging.
