This rechargeable, spill-proof battery is built for everyday riders and powersports enthusiasts who need reliable starts, resistance to vibration, and flexible mounting.

How will this battery improve my motorcycle's starting reliability?

The YT14B-4 supplies 115 cold cranking amps, which supports dependable starts even after periods of inactivity. AGM technology keeps internal resistance low for strong initial current, while the sealed design prevents acid leaks that can degrade terminals or wiring.

• 115 CCA for consistent crank power
• Low internal resistance for rapid energy delivery
• Sealed SLA/AGM design resists leaks and corrosion

Can I mount the battery in different positions on my vehicle?

Yes — the YT14B-4 is designed to be installed in any orientation without spilling, thanks to its sealed AGM construction. That flexibility makes it easier to fit into tight or unusually shaped battery compartments on motorcycles, ATVs, and other powersports machines.

• Mountable in any position without leakage
• Compact footprint: 5.94" x 2.75" x 5.70" (L×W×H)
