Yuasa YTX14AH-BS AGM Motorcycle Battery YUAM62H4A — 12Ah, 210 CCA, Bottle-Supplied (BS) Maintenance-Free

The Yuasa YUAM62H4A YTX14AH-BS is a maintenance-free AGM motorcycle battery supplied dry with an acid pack, offering 210 CCA, 12 Ah capacity and valve-regulated, nonspillable construction.

Designed for modern motorcycles, ATVs and powersport machines, the Yuasa YTX14AH-BS combines improved cold-cranking performance with long-lasting lead-calcium chemistry. The bottle-supplied (BS) version ships dry so you activate the battery when you install it; its AGM separators trap electrolyte for a spill-resistant, low-maintenance unit that resists water loss and holds charge characteristics longer than traditional lead-antimony cells.

What performance improvements does this battery provide?

The YTX H Series boosts starting power with up to 30% more cold cranking amps compared to earlier Yuasa models. That extra CCA helps cold starts and heavy electrical loads while the 12 Ah nominal capacity supports accessories and short multi-start cycles.

• Cold Cranking Amps (CCA): 210 at 0 °F (-18 °C)
• Nominal Capacity: 12 Ah @ 10HR
• Improved starting for cold or high-demand conditions

How does the AGM and lead-calcium design affect reliability?

Absorbed Glass Mat (AGM) separators immobilize the electrolyte, preventing spills and enabling a valve-regulated design that reduces water loss. The lead-calcium alloy keeps the battery’s specific gravity stable much longer than conventional lead-antimony batteries, improving shelf life and on-vehicle reliability.

• AGM construction: nonspillable, vibration-resistant
• Valve regulation: minimized water loss, no refilling required
• Lead-calcium plates: extended preservation of charge characteristics

What does bottle-supplied (BS) mean and how do I activate it?

"Bottle supplied" means the battery is shipped dry with the acid in a separate plastic container for safer transport. You fill the battery with the supplied electrolyte and allow it to stand the recommended time before charging and installation, which minimizes leakage risk during shipping and storage.

• Comes with an acid pack for end-user activation
• Fill, rest, then charge per instructions before use
• Ideal for seasonal storage or shipping safety regulations

Will it fit my bike and what are the physical specs?

The YTX14AH-BS is compact but weighty when filled; verify fitment against your vehicle’s battery compartment and terminal layout. Yuasa includes a 10 mm height spacer for fine adjustments and lists the filled weight so you can confirm supports and mounts.

• Dimensions: 134 mm L × 89 mm W × 166 mm H (5 5/16 × 3 1/2 × 6 9/16 in)
• Includes 10 mm height spacer; filled weight: 11.1 lbs
• Recommended regular charge current: 1.2 A

Who this is for: Riders, mechanics and powersports owners who want a compact, high-CCA, maintenance-free battery that ships dry for safer transport. Choose the YUAM62H4A YTX14AH-BS if you need reliable cold-start performance, AGM nonspillable construction, and extended charge retention compared with older lead-antimony designs. Ensure you follow the included acid-fill and charging instructions for safe activation and maximum service life.
