Marine and leisure applications demand a battery that can handle sustained power draw from multiple onboard consumers without rapid voltage drop or premature failure. The Exide ER350 is a 12V 80Ah dual-purpose leisure battery engineered specifically for boats operating a single battery bank to serve all electrical loads, including navigation electronics, lighting, bilge pumps, and auxiliary equipment.
Manufactured by Exide Technologies under the Exide Dual leisure range, the ER350 is built to withstand the partial state-of-charge cycling typical of marine use, where full recharge between sessions cannot always be guaranteed. The range is rated NCC Class C, confirming independent verification of capacity claims to National Caravan Council standards.
The ER350 measures 270mm × 173mm – 222mm (L × W × H) and sits in a D26 case with Korean B1+B6 hold-down compatibility. It delivers 510A CCA (EN) and 350A MCA, with a rated capacity of 80Ah (C20). Polarity is standard (positive left, code 1). No direct cross-references are listed; confirm fitment against your vessel's battery tray dimensions and hold-down points before ordering.
The ER350 is one of several capacities in the Exide Dual range. Related models include the ER450, ER550, ER600, ET550, ET650, EN750, EN850, and EU80-6, offering a stepped range of capacities for different vessel configurations.
