12A Smart Diagnostic Battery Charger
With battery analyser functions
12V DC 12A

12A Smart Battery Charger, to charge, protect, repair and analyse 12V batteries in vehicles up to 5L. Smart chargers are ideal for lead acid, gel, calcium, AGM and EFB batteries - and essential for maintaining START/STOP vehicles.

The RSC612/RESC612 Smart Charge applies an eight stage cycle, that recharges at the optimum speed, repairs damage to the battery, and automatically switches to a low charge rate once the battery is recharged, ensuring that it maintains its charge level without causing damage through overcharging. The RSC612/RESC612 also has four battery analysis tools, that test start power, the alternator check, battery cranking performance and battery voltage, to give you a full view of your vehicle battery's health.

The RSC612/RESC612 also has maintenance mode - ideal for long term connection - and memory saver function, so it can retain the vehicle's electronics settings (e.g. radio settings) if the battery is disconnected. The winter charge mode is ideal for charging in cold weather. The LCD screen makes it easy to take readings and select charge or analysis settings. This is a comprehensive battery care tool.

Rennline M6 to SAE Battery Terminal Conversion Kit

The Rennline M6 to SAE Battery Terminal Conversion Kit provides a simple and effective solution for converting batteries with female M6 threaded terminals into standard SAE battery posts. Designed for enthusiasts and professionals alike, this high-quality conversion kit allows you to use conventional automotive battery clamps, quick-disconnect connectors and accessory wiring without the need to modify or replace your existing battery cables.

Perfect for Porsche owners upgrading or replacing their battery, the kit offers a clean, reversible installation that preserves your battery while making future maintenance and accessory installation significantly easier. Whether you're fitting an Odyssey AGM battery or another battery using female M6 threaded terminals, the Rennline conversion kit delivers a secure, reliable connection with factory-quality fit and finish.

Each SAE battery post is precision manufactured and supplied pre-threaded at the top, allowing the installation of either M8 or M10 hardware using the included fixings. This makes it quick and convenient to add additional power or earth connections for accessories such as battery chargers, inverters, fuse blocks, motorsport electronics, audio systems or auxiliary equipment without compromising the main battery connection.

Although originally developed for Odyssey AGM batteries, the conversion posts are compatible with most batteries featuring female M6 threaded terminals, making them a versatile upgrade for road cars, classic Porsche restorations, performance vehicles, race cars and off-road applications.

Why Upgrade to the Rennline M6 to SAE Conversion Kit?

Many modern AGM batteries utilise threaded M6 terminals, which can limit compatibility with traditional battery clamps and electrical accessories. The Rennline Conversion Kit eliminates this problem by converting your battery to the industry-standard SAE post configuration, providing greater flexibility while maintaining a neat, professional installation.

Features

• Converts female M6 threaded battery terminals to standard SAE battery posts.
• Compatible with standard automotive battery clamps.
• Allows installation of quick-disconnect battery connectors.
• Ideal for additional accessory power and ground connections.
