AGM Technology
AGM (Absorbent Glass Mat) batteries use fibreglass separators to absorb and retain the electrolyte within the battery. This sealed construction makes AGM batteries maintenance-free and highly resistant to vibration, providing a dependable alternative to conventional flooded leisure batteries for mobile applications.
