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.

What Is This Part?
This is the gasket associated with the battery carrier plate, also described as the seal for the battery tray. It forms part of the battery installation alongside the carrier plate, battery rail and associated fixings. Its role is to seal the carrier-plate interface, while the mounting components retain the battery assembly. The gasket can be renewed separately when its condition makes it unsuitable for refitting.


What Does This Part Do?

  • Seals the carrier plate: Provides the gasket at the battery tray installation.
  • Completes the assembly: Works with the carrier plate as part of the original battery mounting arrangement.
  • Allows separate seal renewal: Enables a damaged gasket to be replaced when the surrounding components remain serviceable.


Why Replace This Part?
A torn, hardened or permanently compressed gasket may no longer seat properly at the carrier plate. Replacement is appropriate when inspection identifies deterioration that prevents the existing seal from being reused correctly.

Inspect the gasket whenever the carrier plate is removed, rather than assuming removal alone makes replacement necessary. While access is available, check the plate, battery rail and fixings for damage or corrosion. Any deterioration of the mating surfaces should also be addressed, as fitting a new gasket does not repair a damaged plate.


When to Replace This Part?

  • Visible damage: Tears, splits or missing sections in the gasket.
  • Loss of shape: Permanent flattening or distortion that prevents correct seating.
  • Age-related deterioration: Hardening or crumbling found during inspection.
  • Damage during removal: The seal is pulled apart or damaged when the carrier plate is lifted.
  • Unsuitable for refitting: The gasket cannot be positioned correctly after checking and cleaning the mating surfaces.


Where Is This Part Fitted?
Location: At the battery carrier plate within the front battery assembly. It is fitted at the carrier-plate sealing interface, close to the battery mounting components.


Product Summary

  • Product: Battery tray / carrier plate seal.
  • Brand: Porsche.
  • Part number: 99650462200.
  • Fitting location: Front battery assembly, at the carrier plate.

Check fitment for your specific vehicle (model, year, engine) before ordering.


What Is This Part?

The battery tray is the supporting platform beneath the battery. It forms part of the mechanical mounting arrangement, alongside the battery retaining rail and fixings where applicable. Its condition matters because the battery needs a sound, correctly seated base before the retaining hardware can hold it properly. Battery removal provides an opportunity to inspect the tray, its mounting points and the surrounding installation.


What Does This Part Do?

  • Supports the battery: Provides the base on which the battery rests.
  • Maintains seating: Helps keep the battery positioned correctly within its mounting arrangement.
  • Completes the mounting assembly: Works with the associated retaining hardware to support secure installation.


Why Replace This Part?
Replacement may be appropriate if inspection finds corrosion, cracks, distortion or damaged mounting points that prevent the tray from supporting the battery correctly. A distorted base can leave the battery sitting unevenly, while deterioration around a fixing can affect the mounting assembly.

Inspect the retaining hardware and surrounding mounting area at the same time. If the battery is loose, check the complete assembly before deciding which component needs replacement. A flat battery, slow cranking or electrical warning messages alone do not establish that the tray is faulty.


When to Replace This Part?

  • Structural deterioration: Corrosion or other damage has weakened the supporting surface or mounting points.
  • Cracks or distortion: The tray is split, bent or no longer allows the correct battery to sit evenly.
  • Damaged fixings: Mounting holes or fixing areas are damaged and cannot retain the tray correctly.
  • Movement after fastening: The battery remains insecure after the correct retaining hardware has been checked and fitted.
  • Damage found during removal: Inspection with the battery removed reveals deterioration that was previously hidden.


Where Is This Part Fitted?
Location: Directly beneath the battery, forming the supporting base of the battery mounting assembly.


Product Summary

  • Product: Battery tray / battery carrier plate.
  • Brand: Porsche.
  • Part number: 99750415100.
  • Purpose: Supports the battery and works with its retaining hardware.
  • Repair context: Replacement of a damaged or deteriorated battery support following inspection.

About Batteries & Chargers

Batteries & Battery Chargers – Reliable Power Solutions for Porsche Performance

Batteries and battery chargers are essential for maintaining your Porsche’s performance, reliability, and electrical health. The battery supplies the power required to start your engine and run all onboard electronics, while a quality charger ensures your battery remains in peak condition during storage or periods of infrequent use. Together, they keep your Porsche ready to perform — whether on the road, at the track, or in the garage.

At Design911, we stock a full range of genuine and manufacturer-quality batteries and battery chargers suitable for the transaxle cars, 911, Boxster, Cayman, Cayenne, Macan, and Panamera models. Our selection includes AGM, lithium, and conventional batteries, along with intelligent smart chargers that optimise battery health, extend lifespan, and ensure efficient energy delivery for every type of Porsche.

What Do Car Batteries and Chargers Do?

  • Car batteries supply electrical power for engine starting, ignition, and all onboard systems, including lighting, infotainment, and climate control.
  • Battery chargers maintain optimal voltage and charge levels, especially during long-term storage, preventing sulfation and premature battery failure.

These components work together to ensure consistent performance, quick starts, and reliable energy storage, especially in high-performance vehicles that demand precision power management.

Why Do Batteries Fail?

Even high-performance batteries degrade over time. Common causes of failure include:

  • Age-related wear reducing charge capacity.
  • Parasitic electrical drain from onboard electronics.
  • Temperature extremes accelerating internal deterioration.
  • Infrequent use leading to discharge or sulfation.
  • Poor charging habits or alternator issues causing undercharging or overcharging.

Warning signs include slow cranking, dim lights, battery warning lights, or complete electrical loss.

Why Replace or Maintain Your Battery?

Replacing a weak or failing battery ensures your Porsche always starts reliably and powers its advanced electronics safely. Using a quality charger also helps maintain optimal battery condition, extending lifespan and performance.

Benefits include:

  • Improved starting reliability and voltage stability.
  • Protection against battery drain and electrical faults.
  • Longer service life through proper maintenance charging.
  • Manufacturer-quality performance and compatibility with Porsche systems.

Our chargers feature smart technology that automatically monitors and adjusts charging rates — perfect for seasonal storage or vehicles with limited use.

1. How long does a Porsche battery last?
Most Porsche batteries last between 4 and 6 years, depending on usage and climate. Regular use, proper charging, and avoiding deep discharges can significantly extend battery life. Using a smart charger during long-term storage helps maintain health and performance.

2. What are the signs of a failing Porsche battery?
Common signs include slow engine cranking, dim lights, flickering dashboard electronics, or battery warning lights. If your Porsche struggles to start after being parked for a few days, the battery may be weak or not holding charge.

3. Do I need a special charger for my Porsche battery?
Yes — modern Porsches often use AGM or lithium-ion batteries that require intelligent chargers with microprocessor control. These chargers adjust voltage and current automatically, preventing overcharging and extending battery lifespan.

4. Can I use a trickle charger on my Porsche?
While trickle chargers can keep a battery topped up, smart battery chargers are safer and more effective for Porsche vehicles. They monitor charge levels and automatically switch to maintenance mode once full, preventing damage or overheating.

5. How do I prevent Porsche battery drain when not driving?
If your Porsche is parked for long periods, connect a smart charger or maintainer, disable unnecessary electrical systems, and avoid leaving key fobs nearby (which can keep electronics active). This ensures the battery stays charged and ready to go.
