Maximise Charging Performance for 12V Auxiliary Battery Systems

Conventional alternator charging systems often leave auxiliary batteries undercharged, reducing available capacity and extending recharge times. This 12V 130A Alternator-to-Battery Charger overcomes these limitations by delivering a fully automatic multi-stage charging profile that optimises voltage and current for faster, more efficient charging. Combining intelligent battery charging and split-charge functionality into a single compact unit, it helps maximise battery performance for marine, caravan, motorhome and other 12V dual-battery applications.

Key Features

• 130A Charging Output – Delivers up to 130A of intelligent charging to maximise charging performance for compatible 12V auxiliary battery systems.
• Optimised Multi-Stage Charging – Automatically adjusts the charging profile to improve battery charging efficiency and support longer battery service life.
• Integrated Split-Charge Functionality – Combines battery charging and battery isolation into one compact unit, reducing installation complexity.
• Boosts Alternator Charging Performance – Increases charging voltage to help auxiliary batteries reach a higher state of charge than conventional alternator systems.
• Compatible with Single or Twin Alternators – Supports installations using one or two alternators within the charger's rated capacity.
• Battery Temperature Compensation – Automatically adjusts charging characteristics when used with the optional battery temperature sensor.
• Alternator Temperature Protection – Supports an optional alternator temperature sensor that temporarily suspends charging if excessive temperatures are detected.
• Remote Display Compatible – Optional remote display provides charging information, system status and configuration options.
• No Alternator Modification Required – Installs without requiring internal alternator modifications, making it suitable for a wide range of existing electrical systems.
• Suitable for 12V Mobile Power Systems – Ideal for boats, caravans, motorhomes, RVs, 4WDs and other vehicles requiring improved auxiliary battery charging.

This 12V 130A Alternator-to-Battery Charger provides a practical solution for improving charging efficiency and maintaining healthier auxiliary batteries. Its intelligent charging technology helps maximise available battery capacity while simplifying dual-battery installations.
