Designed for Harley performance

Engineered to cope with large-displacement engines, heated grips, advanced infotainment, and aftermarket lighting, TIANDONG batteries provide consistent cranking amps and stable voltage under load. Products are optimized for high discharge and repeated starting cycles common to Harley-Davidson models and heavy cruisers.

Our lineup includes high-energy lead-based solutions and sealed maintenance options produced to strict production standards. Available sizes and terminal layouts match common Harley battery trays and hold‑down systems, enabling easy replacement and minimal rider downtime.

Fitment and application guidance

Each battery spec lists cold cranking amps (CCA), reserve capacity, and physical dimensions so you can quickly identify correct replacements for Touring, Softail, Dyna, Sportster, and custom frames. TIANDONG supports OEM-style specs and offers tuning for accessory-heavy builds.
