Key Features & Benefits

• 6 Volt / 11 Amp-Hour Output: Sized correctly for 6V electrical systems, providing the sustained capacity needed for starting and running vintage or classic powersports equipment.
• Polypropylene Case & Cover: The durable polypropylene construction resists gasoline and oil exposure — a real-world advantage for a battery mounted close to the engine in older motorcycle frames — and holds up through extreme weather conditions.
• Poly-Seal Terminal Design: Helps prevent electrolyte leaks around the terminals, contributing to a cleaner, safer installation and reducing the risk of corrosion on surrounding electrical components.
• Conventional Battery Family: A conventional (wet/flooded) design that is compatible with older charging systems not designed for AGM or lithium chemistry — no special charger required beyond a standard 6V battery charger.
• Hardware Included: Comes with the necessary mounting hardware so you have what you need to complete the installation.
• One-Year Manufacturer's Warranty: Yuasa backs this battery with a one-year warranty from the date of purchase, giving you confidence in your investment.

Frequently Asked Questions

Q: Does this battery come ready to use, or does it need to be filled with electrolyte first?
A: The Yuasa 6N11-2D is a conventional (wet/flooded) battery. Electrolyte is sold separately. You will need to fill and charge the battery before its first use, following Yuasa's activation instructions. Make sure you source the correct battery acid and a compatible 6V charger.

Q: Will this battery work in a 12-volt motorcycle?
A: No. This is a 6-volt battery intended exclusively for vehicles with 6V electrical systems. Installing a 6V battery in a 12V system will not provide adequate power and could damage your electrical components. Always match battery voltage to your vehicle's system voltage.

Q: What vehicles does the 6N11-2D fit?
A: This battery fits any application specifying a 6N11-2D replacement. Verified fitment includes the Honda C70M / C70 Passport. Because many vintage bikes across multiple brands have used 6V systems, it's worth cross-referencing the 6N11-2D part number against your owner's manual or current battery label to confirm compatibility.

Q: Does this purchase come with a warranty?
A: Yes. Yuasa covers this battery with a one-year manufacturer's warranty from the date of purchase.
