Maintenance-free marine battery with sealed cover. Range of batteries for mixed use (starter and service) *SMF type Sealed Maintenance Free (except SBE230301) *Handling handle *Charge indicator on the whole range. *Tilt range: 45°. *Reliable energy recovery in severe climatic conditions. *Wire terminal (ø8mm) is available on model 108BF. *Very low self-discharge. DOLPHIN PRO batteries not only have a large energy reserve, they also offer excellent performance in all conditions. The 140A / 180A and 230A models are semi-traction batteries, and the DOLPHIN PRO range is maintenance-free for mixed and intensive use. CALCIUM / CALCIUM TECHNOLOGY A new technology known as 'expanded metal' or 'continuous casting'. Used by the world's leading manufacturers, it enables very thin sheets to be produced and a larger quantity to be housed in a tray. The advantages: greater start-up power, better current conductivity, virtually zero self-discharge. Calcium/calcium technology also increases the number of cycles (discharge + charge) and eliminates water consumption.
