Q 1. What are the dimensions of the Exide 12N9-4B-1 battery?

A. The battery measures 135mm in length, 75mm in width, and 140mm in height including the terminal. It is housed in a Case C43 enclosure with a Hold-Down B00 configuration.

Q 2. What voltage and capacity does the 12N9-4B-1 provide?

A. This battery is rated at 12V with a capacity of 9Ah (C20) and a Cold Cranking Amp (CCA) rating of 85A to EN standard, making it suitable for typical motorcycle engine-starting applications.

Q 3. What is the polarity configuration of the Exide 12N9-4B-1?

A. The battery has a Polarity 1 configuration. Installers should verify this against the vehicle manufacturer's wiring diagram and battery tray layout before installation to avoid connection errors.

Q 4. Which cross-reference codes does the 12N9-4B-1 correspond to?

A. This battery cross-references to the YB9-B and FB9-B designations, which are commonly referenced across Japanese and European motorcycle battery fitment guides.

Q 5. Is the Exide 12N9-4B-1 suitable for start-stop motorcycle systems?

A. Compatibility with start-stop systems has not been confirmed for this battery. Refer to the product label and your vehicle manufacturer's specification to determine suitability for start-stop applications.

Q 6. Does the Exide 12N9-4B-1 require any maintenance or initial filling?

A. As a GEL battery, this unit is sealed and maintenance-free. It does not require acid filling or electrolyte checks during its service life, unlike conventional dry-charged motorcycle batteries.

Q 7. What does the warranty cover for the 12N9-4B-1?

A. The battery is covered by a 1-year manufacturer's warranty against defects in materials and workmanship under normal operating conditions. Warranty claims resulting from misuse, incorrect fitment, or failure to follow installation guidelines are not covered.

Q 8. Are there alternative variants available if the 12N9-4B-1 does not suit my application?

A. Yes. A related GEL variant, the GEL12-19 (PID000138096), is available within the Exide Equipment Gel range and may be suitable for applications requiring a higher capacity rating.

Q 9. How is the Exide 12N9-4B-1 delivered, and what is the returns policy?

A. This battery is classified as unsuitable for standard courier shipment due to its GEL chemistry and associated transport regulations. Please contact PartsForMachines directly to discuss availability and shipping options. A 30-day returns policy applies to eligible orders.

Q 10. What type of battery technology does the 12N9-4B-1 use?

A. It uses GEL electrolyte technology, in which the acid is immobilised within a silica compound. This eliminates free liquid, reduces leakage risk, and improves vibration resistance compared to conventional wet-fill batteries — a practical advantage in motorcycle use.
