- Lithium-Ion: Lightweight and long-lasting but more expensive.
My Buying Tips for Replacing the Battery
- Check your owner’s manual: It confirms the exact specifications and any model-specific recommendations.
- Look for OEM or reputable aftermarket brands: Brands like Yuasa or Harley-Davidson OEM batteries are reliable.
