Yuasa motorcycle AGM battery YUAM6212B (YT12B-BS) 10Ah 210 CCA — dry-pack, maintenance-free

Yuasa YUAM6212B (YT12B-BS) is a bottle-supplied Absorbed Glass Mat (AGM) motorcycle battery that delivers reliable, maintenance-free starting power for many Ducati, Kawasaki, Triumph and Yamaha bikes when activated.

This dry-packed Yuasa battery ships with electrolyte in a separate bottle so you fill it only when ready, combining long shelf life with AGM technology that prevents spills, reduces water loss and keeps charge longer than conventional lead-antimony designs. With a compact footprint and 210 C.C.A., it’s engineered for high-crank starts in sportbikes, cruisers and select scooters while staying vibration-resistant and valve-regulated for safer handling.

How does this battery differ from a conventional flooded motorcycle battery?

The YUAM6212B uses Absorbed Glass Mat separators to immobilize electrolyte inside the plates, making it nonspillable and safer to mount in various orientations. Its valve-regulated AGM design minimizes water loss so you don’t need to add distilled water, and the dry (bottle supplied) packaging preserves capacity until activation.

• AGM technology prevents electrolyte sloshing and reduces corrosion
• Valve-regulated design eliminates routine water top-ups
• Bottle-supplied dry pack extends shelf life before first use
• Lead-calcium alloy holds specific gravity longer than lead-antimony types

Will this battery fit my motorcycle or scooter?

The Yuasa YUAM6212B (YT12B-BS) is a compact battery (150 x 69 x 130 mm) that suits many sportbikes, naked bikes, adventure models and select scooters. Check the listed compatible models or compare physical dimensions and terminal layout to your OEM battery to confirm fitment.

• Dimensions: 6 in (L) x 2 3/4 in (W) x 5 1/8 in (H)
• Weight when filled: approx. 9 lbs
• Common fits include Ducati, Triumph, Kawasaki and Yamaha models
• Compare terminal orientation and mounting bracket before purchase

What are the performance specs and charging recommendations?

This battery delivers 10 Ah capacity (10HR) and a cold cranking amperage of 210 C.C.A. at 0°F (-18°C), enough for high-compression motorcycle engines. Use a motorcycle-compatible smart charger and apply a regular charge current around 1 A for optimal life; store charged and top up with a charger if the bike is inactive for long periods.

• Capacity: 10 Ah @ 10HR
• Cold Cranking Amps: 210 C.C.A. @ 0°F (-18°C)
• Recommended regular charge: ~1 A (use compatible smart charger)
• Periodic charging advised during long storage to prevent sulfation

How do I activate and handle the bottle-supplied battery safely?

The YT12B-BS ships dry and includes an electrolyte bottle for user activation; follow Yuasa’s instructions for filling, seating the acid bottle, and venting. After filling, allow any initial stabilization period, then charge as recommended and install using proper PPE and tools to avoid spills.

• Fill only when ready to use; keep bottle upright and follow label steps
• Wear eye protection and gloves during activation
• Charge after filling according to manufacturer guidance
• Dispose empty acid bottle per local hazardous waste rules

Who is this for: The Yuasa YUAM6212B YT12B-BS is aimed at riders and mechanics who want a compact, high-cranking AGM battery with extended shelf life before activation. It’s well suited to sport and performance motorcycles (Ducati, Kawasaki, Triumph, Yamaha), enthusiasts who winter-store bikes, and anyone preferring the safety and maintenance advantages of valve-regulated AGM technology over traditional flooded batteries.
