Yuasa motorcycle AGM battery YTX14H-BS (Bottle Supplied) 12 Ah, 240 CCA, maintenance-free

Yuasa YUAM6RH4H YTX14H-BS is a maintenance-free AGM motorcycle battery supplied dry with an acid pack for user activation, delivering 240 CCA and reliable starting power.

This Yuasa YTX H Series battery combines lead‑calcium alloy and Absorbed Glass Mat (AGM) technology to offer higher cold cranking performance and long shelf life. Shipped in Bottle Supplied (BS) dry form, you fill it with the included electrolyte when you’re ready to install, which keeps the battery safe during transport and storage. The valve‑regulated design prevents water loss and removes the need for routine watering, making it a practical upgrade for motorcycles, ATVs, scooters and powersport applications that demand dependable starts and low maintenance.

How much starting power does this battery provide?

The YTX14H-BS delivers 240 cold cranking amps (CCA) at 0 °F (-18 °C), giving a noticeable boost for cold starts compared with many standard lead‑acid designs. Its 12 Ah capacity (10‑hour rate) supports accessory loads and short rides between charges. The improved lead‑calcium chemistry helps maintain specific gravity longer, so it retains readiness during storage.

• Cold Cranking Amps: 240 CCA at 0 °F (-18 °C)
• Capacity: 12 Ah (10HR)
• Weight with acid: 10.6 lbs (approx.)
• Enhanced lead‑calcium alloy for longer charge retention

What makes the AGM and bottle‑supplied design useful for me?

AGM separators trap electrolyte in glass mats, creating a nonspillable battery that tolerates vibrations and mounting angles common on motorcycles. The Bottle Supplied (BS) format ships the battery dry with the acid in a separate container, reducing shipping risk and allowing on‑demand activation. Once filled and allowed to settle, the battery is ready for immediate installation with minimal fuss.

• Absorbed Glass Mat prevents spills and improves vibration resistance
• Valve regulated to eliminate routine refilling and water loss
• Dry shipment with acid pack for safer transport and longer shelf life
• Simple fill-and-install process when you’re ready to use it

Will this battery fit my bike and how big is it?

The YTX14H-BS follows common YTX H Series dimensions for many powersport models, but always confirm fitment against your vehicle’s battery tray and terminal layout. Its compact footprint balances capacity and space efficiency to fit mid‑sized motorcycles, cruisers and some ATVs. Keep an eye on terminal orientation and hold‑down type when comparing to your OEM part number.

• Length: 6 in (150 mm)
• Width: 3 7/16 in (87 mm)
• Height: 6 3/4 in (145 mm)
• Check terminal layout and tray dimensions before purchase

How should I charge, activate and maintain this battery?

Fill the dry battery with the included acid pack following the manufacturer instructions, then let it absorb for the recommended time before charging or installation. Use a charger compatible with AGM batteries and charge at the specified regular current (approximately 1.4 A) to avoid overcharging. After installation the valve‑regulated, maintenance‑free design removes the need for water top-ups, but periodic voltage checks and proper charging keep the battery performing best.

• Fill with supplied electrolyte and allow proper absorption time
• Recommended regular charge current: about 1.4 A
• Use an AGM‑compatible charger and avoid fast, uncontrolled charging
• Valve‑regulated design means no watering required after activation

Who is this for: The Yuasa YUAM6RH4H YTX14H-BS suits motorcycle and powersport owners who want a durable, maintenance‑free battery with improved cold start performance and safe, dry shipment. It’s a good choice for riders who store vehicles seasonally, need vibration resistance, or prefer activating a fresh battery at installation. Ensure fitment and terminal layout match your machine before ordering.
