The Mastervolt 62001600 AGM 12/160 is a Group 4D, 12-volt, 160Ah sealed Absorbed Glass Mat (AGM) marine battery engineered for dual-purpose performance. It combines both starter and service functions into a single maintenance-free unit, making it an ideal universal battery for marine, RV, and powersports applications.
In AGM batteries, the electrolyte — a mixture of water and sulphuric acid — is largely absorbed in fiberglass matting rather than free-flowing liquid. This sealed construction means there is no gas formation under normal use, no electrolyte spillage risk, and no ventilation requirements, allowing the battery to be mounted in virtually any orientation or location aboard a vessel.
Key Features:
- Dual-purpose design — serves as both a starter battery for high-current engine cranking and a service battery for onboard lighting, instrumentation, and electronics
- High cranking power — 550A CCA (DIN) / 870A CCA (SAE), delivering the same initial power surge as a 180Ah flooded lead-acid battery
- 160Ah nominal capacity (C20 rating) at 12V DC
- Glass-fibre AGM technology — ensures low internal resistance for fast charge acceptance and high discharge rates
- Thicker plate construction — extends overall battery lifespan and supports medium cyclical use
- Fully sealed and maintenance-free — no watering, no terminal corrosion from outgassing, no spill hazard
- Universal terminal compatibility — M8 / A-type terminals; battery poles are removable and compatible with every standard battery terminal type
- Max charge current: 45A — compatible with Mastervolt's 3-step Plus charging method
- First-rate condition after winter storage due to very low self-discharge rate
- Two-year manufacturer warranty
The Mastervolt AGM 12/160 is a direct, high-performance upgrade from flooded (wet cell) lead-acid batteries. Its Group 4D form factor and robust 19.1" x 6.7" x 9.5" footprint fit standard large-format battery boxes and trays. Whether used as a primary house bank, dedicated engine starter, or combination battery, this AGM delivers reliable power in demanding marine environments.
