Understanding the exact size you need can vary by production year and trim level, so it’s important to verify the specification for your specific machine before purchasing a battery. Below you’ll find common sizes, how to confirm the correct one, and tips for replacement.
Battery sizes commonly found on the Rancher 350
Different Rancher 350 generations used slightly different battery specifications. The two replacements you’re most likely to encounter are listed below.
- YTX14-BS: A 12V, approximately 12 Ah battery, widely used across many ATVs and a common fit for various Rancher 350 models.

Choosing between these options depends on your specific year and model. If the battery label or OEM catalog lists one of these sizes, use that exact group size to ensure proper fit and electrical performance.
How to confirm the correct battery size for your Rancher 350
- Check the existing battery’s label for the group size (for example, YTX14-BS or U1-12) and the CCA/Ah rating.
- Consult your owner’s manual or the OEM parts catalog for your VIN/year to confirm the recommended battery group size and CCA rating.
- Measure the battery compartment and terminal layout to ensure the replacement will fit and the terminals align with cables without strain.
- If in doubt, contact a Honda dealer or reputable ATV parts supplier with your VIN to get the exact OEM specification.
Accurate verification helps prevent fit issues and ensures reliable starting, especially in cold climates or heavy use.

Beyond the size, consider these practical notes for Rancher 350 battery replacement:
- Cold-cranking amps (CCA): Ensure the replacement meets or exceeds the OEM CCA rating for reliable starts in your climate.

- Installation: Disconnect the negative (-) cable first, then the positive (+) when removing old battery; reconnect in reverse order.
