| YTX9-BS | 12V | 8–9Ah | 150cc–250cc | Premium scooters, sport bikes | Higher cranking power (CCA) |
| YTX12-BS | 12V | 10–12Ah | 250cc+ | Large motorcycles | High capacity & stability |
3. How to Choose the Right Motorcycle Battery
Step 1: Match the Original Battery Model (Best Method)
If the old battery is available, always replace with the same model.
Example:
- Old battery: YTX7L-BS → New battery: YTX7L-BS
This ensures 100% compatibility
Step 2: Select by Engine Size (When Model Is Unknown)
| Engine Size | Recommended Model |
|---|---|
| 50cc – 110cc | YTX4L-BS / YTX5L-BS |
| 125cc – 150cc | YTX7L-BS |
| 150cc – 250cc | YTX9-BS |
| 250cc and above | YTX12-BS |
Step 3: Select by Usage Scenario
| Application | Recommended Model |
|---|---|
| Daily commuting | YTX7L-BS |
| Delivery / high-frequency use | YTX7L-BS / YTX9-BS |
| High-performance motorcycles | YTX9-BS / YTX12-BS |
| Budget-sensitive markets | YTX4L-BS / YTX5L-BS |
4. Motorcycle Battery Type Comparison
| Type | Description | Best Market |
|---|---|---|
| AGM Maintenance-Free | No water required, sealed design | Global mainstream market |
| GEL Battery | Heat-resistant, deep cycle performance | Delivery & commercial use |
| Flooded Battery | Traditional type, low cost | Price-sensitive markets |
AGM batteries are now the global replacement standard
5. Motorcycle Battery Compatibility Examples
To help buyers better understand application scenarios:
- YTX7L-BS → Honda 125cc–150cc motorcycles / Yamaha scooters
- YTX9-BS → Higher-performance scooters and touring bikes
- YTX5L-BS → Small commuter motorcycles and entry-level scooters
Compatibility may vary slightly by model year and region.
6. Recommended Wholesale Stock Models
For distributors and importers, it is recommended to focus on the following core models:
- YTX7L-BS (Top-selling universal model)
- YTX9-BS (High-margin upgrade model)
- YTX5L-BS (Entry-level coverage model)
These three models cover more than 80% of global motorcycle battery demand
7. Common Mistakes in Battery Selection
Choosing based only on Ah (capacity)
Ignoring physical dimensions
Incorrect terminal polarity
Using low-spec battery for high-performance motorcycles
These mistakes often lead to installation failure or poor performance.
8. Why AGM Motorcycle Batteries Are the Market Standard
AGM (Absorbent Glass Mat) batteries are widely used because:
- Maintenance-free design
- Strong vibration resistance
- Stable starting performance
- Longer service life compared to flooded batteries
This is why most OEM motorcycles now use AGM batteries as standard.
9. Not Sure Which Battery to Choose?
You can provide any of the following information for quick matching:
- Motorcycle brand and model
- Old battery photo
- Battery model number
- Battery dimensions
Our technical team can confirm compatibility within 24 hours.
