Product Details

The Mastervolt AGM 12/70 (Group 27) is a sealed, maintenance-free 12V 70Ah dual-purpose marine battery engineered to handle both engine starting and onboard service loads. Using Absorbed Glass Mat (AGM) technology, the electrolyte is fully absorbed in fiberglass matting, eliminating free liquid acid and making the battery completely spill-proof and safe for installation in virtually any orientation or compartment location.

This battery delivers high cold-cranking performance—rated at 460 CCA (SAE)—making it an excellent choice for engine starting, bow thrusters, winches, and other high-current demand applications. It also supports medium cyclical use, powering onboard lighting, navigation instruments, and electronics as a reliable house/service battery.

Key Features:

  • Dual-purpose design — functions as both a starter and service battery
  • 70Ah capacity (C20) with 460A CCA (SAE) cold cranking power
  • AGM glass-fibre technology ensures low internal resistance and fast high-current discharge
  • Thicker plates for extended service life and improved cycle durability
  • Fully maintenance-free — no watering, no venting required under normal use
  • Sealed and spill-proof — safe for use in enclosed spaces and difficult-to-access compartments
  • Removable M8 battery terminals — compatible with every standard battery terminal configuration
  • Low 3% monthly self-discharge rate — retains charge well during off-season storage
  • Drop-in upgrade for flooded lead-acid batteries in Group 27 applications
  • Two-year warranty

Specifications:

  • Voltage: 12V DC
  • Capacity: 70Ah (C20, to 10.5V cutoff)
  • CCA (SAE): 460A
  • Max Charge Current: 19.5A
  • Terminal Type: M8 (removable/interchangeable)
  • Dimensions (L × W × H, including terminals and handles): 13.7" × 6.6" × 7.0"
  • Weight: 46 lbs
  • Group Size: 27

The Mastervolt AGM 12/70 is compatible with Mastervolt's 3-step Plus charging method and works seamlessly with standard marine chargers. Whether upgrading from a conventional flooded battery or outfitting a new vessel, this Group 27 AGM delivers the reliability and versatility demanded by serious mariners.
