The Honda TRX700XX uses a 12-volt sealed lead-acid battery. Stock capacity is generally in the 7–9 ampere-hour range, though the exact group size and capacity can vary by year. To be sure, check the OEM parts fiche for your specific year and VIN.
Battery size basics for the TRX700XX
Because Honda updated the TRX700XX during its production run, the exact battery footprint and rating can differ by model year. In practice, most TRX700XX machines use a compact 12V battery, with common group sizes seen in this family of ATVs being YTX9-BS or YTX12-BS. The Ah rating typically falls around 7–9 Ah for smaller, space-efficient fits and rises toward 12 Ah for larger variants that share the same under-seat bay.
- YTX9-BS: 12V, commonly around 7–9 Ah; compact footprint that fits in many TRX700XX battery bays.
- YTX12-BS: 12V, commonly around 12 Ah; larger footprint that may be used in some revisions or similar Honda models.
These are representative examples. The exact group size and capacity depend on the year and specific VIN, so verify with the OEM fiche or a Honda dealer for your machine.
How to verify the exact battery size for your TRX700XX
- Consult the owner's manual or the official Honda parts catalog for your exact year and VIN.
- Measure the available battery bay and compare with standard group sizes (YTX9-BS vs YTX12-BS) to confirm fit.
- Look at the battery label on your current unit for model number and Ah rating; use that information to source a direct replacement.
- When in doubt, contact a Honda dealer or authorized parts retailer with your VIN to obtain the precise OEM battery specification.
Having the correct battery size ensures proper fit, charging, and electrical performance, especially in cold starts and high-demand riding conditions.
Notes on replacement and compatibility
Always replace with a 12V sealed lead-acid battery of the correct group size for your TRX700XX. If you choose a higher capacity (Ah) than specified, ensure the physical fit is still compatible with the battery bay and terminals. If you opt for a non-OEM battery, select a reputable 12V ATV/MC battery with the same or better cold-cranking amps (CCA) and a compatible fit.
Summary

The exact capacity typically ranges from about 7–9 Ah for compact fits up to around 12 Ah for larger variants, depending on the year. To ensure a correct replacement, consult the OEM parts fiche or a Honda dealer for your specific year and VIN, and verify physical dimensions and terminal layout before purchasing.
