⚓ Globatt M27 Marine Deep Cycle (12V 100Ah SMF)

“Marine Grade. Zero Maintenance.” The 2026 Power Standard for Sea & Shore.

Built with Ca-Ca (Calcium-Calcium) technology and high-density active material, the Globatt M27 is specifically designed to resist the high-vibration environment of sea travel. Its Dual-Purpose nature means it can reliably start outboard engines up to 350hp while simultaneously powering on-board electronics like fish-finders, GPS, and cabin lights

✨ Key Technical Features

• 🔄 Deep Cycle Capability:

  Utilizes thicker lead plates and a high-density paste. This allows the battery to be discharged to a deeper level than a car battery without damaging the internal cells, making it perfect for running trolling motors or off-grid lighting.

• 🛡️ Robust Marine Case:

  Constructed with high-impact polypropylene to withstand the constant pounding and vibrations of marine hulls. The heat-sealed cover ensures the battery remains leak-proof even in choppy waters.

• ⚓ Dual-Terminal Design:

  Features both standard tapered posts (for engine cables) and threaded wing-nut studs (for accessory wiring). This simplifies the connection of multiple electronics like bilge pumps, radios, and small fridges.

• 🛠️ Sealed Maintenance-Free (SMF):

  A completely closed system with a built-in “Magic Eye” hydrometer. No topping up of water is required, and the integrated flame arrestor prevents external sparks from igniting internal gases—a vital safety feature in boat bilges.

• 🔋 Anti-Corrosion Grids:

  The silver-calcium alloy used in the plates is highly resistant to the humid, salty air of the Singapore Straits, ensuring a longer service life and better charge retention during the off-season.
