Leoch is one of the world’s leading multi-range battery manufacturers. The Leoch JIS / Automotive AGM line is engineered to deliver premium performance and durability. Unlike traditional flooded batteries, AGM technology encapsulates the acid in fibreglass mats — allowing the battery to be mounted in any orientation and improving vibration resistance.
AGM (versus flooded) advantages include:
No free acid — safer, leak-proof installation
Better vibration tolerance — ideal in rough driving conditions
Zero maintenance — no topping up of electrolyte
Longer shelf life & lower self-discharge
These features make Leoch AGM batteries an excellent choice as original equipment replacements or upgrades.
