Description
The Mastervolt AGM-SL 12/150 is a powerful, maintenance-free battery designed for applications where space efficiency and high performance are essential. Utilizing advanced AGM (Absorbed Glass Mat) technology, the electrolyte is fully absorbed into glass-fibre mats, making the battery spill-proof, vibration-resistant, and entirely gas-free under normal use. This allows installation in virtually any position without ventilation requirements.
Engineered with a slim footprint, the AGM Slim Line series reduces volume and weight by up to 15%, enabling maximum power storage in minimal space—perfect for marine, mobile, automotive, and off-grid energy systems. Despite its compact dimensions, the battery supports very high discharge rates, making it suitable for starter applications and systems requiring rapid bursts of energy.
The unscrewable M6 terminals allow easy integration with any standard battery connection. With robust construction, high cold-cranking performance, and reliable deep-cycle capability, the AGM-SL 12/150 stands out as a universal, long-lasting energy solution.
