The Banner Group, with its two business units 'Automotive' and 'Energy Solutions', is a leading international provider of Porsche battery solutions.The company has been producing batteries for all types of vehicles since 1937. The automotive sector covers an extensive product portfolio with starter, on-board network and leisure batteries in original equipment (OE) and retrofitting (IAM). These products are mainly developed and produced at the company headquarters in Leonding (Austria).

A Quick Look at Banner

Banner information on this page is based on details supplied by the manufacturer or distributor, plus any OE references provided with the parts.

Choosing the Right Fit for Your Porsche

Where Banner is listed for Porsche, use the supplied model coverage and OE references to confirm suitability. Check details that commonly affect fitment such as model year, side/position, and connector type where relevant.

• Typical reasons to choose or replace Banner batteries include short-trip use, storage periods, or high electrical demand where stable voltage reduces “ghost faults” and improves starting reliability.
• Low battery voltage can trigger multiple warning lights, cause start-stop issues, and lead to intermittent electrical faults that disappear after charging.
• Practical checks include confirming overall battery health first, then testing charging voltage and load capacity before blaming individual control units.
• For some Porsche models, battery registration or coding may be required after replacement, so always verify the procedure for your specific car.
• Using a smart battery conditioner during storage helps maintain correct voltage and reduces the risk of flat batteries and spurious fault codes.
• Always match the battery technology (e.g. AGM where specified) and capacity to the original specification to avoid system conflicts.

Browse by Category

If you already know the area you are working on, start with the category and then filter by Porsche model. Where real-world symptoms and typical reasons to replace are provided, use them to keep the wording grounded.

Engine Electrical — Engine electrical parts are replaced when Porsche owners experience starting, charging, ignition, or sensor-related faults that affect drivability, such as intermittent no-start, misfires, rough running, warning lights, or heat-related failures. Switching to known-quality components helps avoid repeat issues and misleading fault codes.

• Before replacing engine electrical parts, confirm basic checks such as battery condition, grounds/earth straps, and connector corrosion, and use fault codes as guidance rather than the sole basis for replacement.
• Where possible, verify suspected components with testing (power, ground, and signal) so you replace only what is actually faulty.

Batteries & Chargers — Batteries and chargers are changed when the existing battery will not hold charge, cranks slowly, or repeated flat-battery incidents and low voltage start causing electrical faults. Porsche owners also upgrade when cars are stored or driven infrequently, choosing correct technology (such as AGM where applicable) and smart maintainers to suit their usage.

• Use a smart charger or maintainer matched to the correct battery type instead of a basic trickle charger, especially on modern Porsche models.
• If the car goes flat when parked, check for parasitic drain and confirm the battery’s resting and cranking voltage before assuming other electrical faults.
