Marine Batteries — Common Questions

• What is the difference between a marine starting battery and a deep cycle battery? +
  A marine starting battery delivers a high burst of cranking current to start an engine. A deep cycle battery is designed for sustained power delivery over time — running navigation lights, a fish finder, bilge pump, or other 12V accessories. Using a starting battery for sustained house loads will shorten its life significantly.
• Do you stock batteries for jet skis? +
  Yes — we stock Bosch powersport batteries suitable for jet ski applications. Call ahead on 0800 100 876 with your make and model and we'll confirm the right battery and price before you come in.
• Can I use a car battery in my boat? +
  Not recommended. Automotive batteries are not built to handle the vibration, moisture, and deep discharge cycles that marine use involves. Marine batteries use reinforced plate construction and sealed designs to handle the marine environment. Using a standard automotive battery in a boat will reduce its service life significantly.
• How much does a marine battery cost? +
  Marine battery pricing depends on the M-series size and whether you need a starting, deep cycle, or dual-purpose battery. Call us on 0800 100 876 with your application and we'll confirm the right battery and price.
• Do I need to call ahead for a marine battery? +
  Yes — we recommend calling ahead on 0800 100 876 to confirm stock before making the trip. Marine batteries turn over less frequently than automotive stock and availability varies.
• What brands of marine battery do you stock? +
  We carry the Bosch marine range — starting batteries (HCM24, HCM27, HCM31) and deep cycle batteries (DC24, DC27, DC31). Call us with your application and we'll confirm the right model.
