The Shadow 750 from 2004 uses a 12-volt motorcycle battery, typically a sealed lead‑acid unit. A common aftermarket replacement is the YTX12‑BS (or YTX14‑BS) depending on the bike’s tray size and terminal layout.
The exact specification can vary by model within the Shadow line and by market, so always verify the battery label or the official owner's manual before purchasing a replacement.
Battery type and common replacements
The following options cover what most 2004 Shadow 750 owners encounter when replacing a tired battery.
- Voltage: 12V nominal (standard for motorcycles).
- Battery construction: sealed lead-acid, typically maintenance-free; replacements are usually AGM or a sealed flooded type with proper venting if required.
- Capacity: commonly in the 11–14 Ah range for mid‑size bikes in this class, affecting cranking power and run-time.
- Popular replacement models: YTX12‑BS is the most widely used 12V equivalent; YTX14‑BS may be used if the tray space and terminal layout permit a larger case. OEM Honda part numbers vary by market and year; aftermarket equivalents with the same 12V rating and similar dimensions are commonly offered.
Concluding: Verify the fit by checking the battery tray dimensions, terminal configuration (positive/negative positions), and the exact height and width. If in doubt, bring your current battery or the manual to a shop to ensure compatibility.
How to verify the exact fit for your bike
Before buying, measure the space, note where the terminals sit, and compare to your chosen replacement’s dimensions and terminal orientation. Ensure the battery fits under the seat and inside the battery box with adequate clearance. When possible, consult the owner's manual or a Honda dealer for the OEM specification for your VIN.
In practice, many 2004 Shadow 750 models accept a standard 12V AGM battery such as YTX12‑BS or YTX14‑BS, but regional variations can apply. Always confirm the precise spec for your bike before purchasing.
Summary
The 2004 Honda Shadow 750 requires a 12‑volt lead‑acid motorcycle battery, typically a sealed, maintenance‑free type. Common replacements include the YTX12‑BS or YTX14‑BS, among other 12V equivalents, with exact fit depending on tray size and terminal layout. Verify label specifications, dimensions, and polarity to ensure a proper match.
