The Honda Foreman 500 runs on a 12-volt, maintenance-free sealed lead-acid battery. The most common replacement is a YTX14-BS group-size battery, though some years use YTX12-BS. Always verify the exact size from your battery label or service manual.
Battery type and specifications
Most Foreman 500 models use a standard 12-volt sealed lead-acid battery with about 12 amp-hours of capacity. Variation by year is possible, so the key is to match the group size and terminal layout to your ATV’s battery compartment. When shopping, look for a battery labeled with the group size YTX14-BS (or YTX12-BS for certain early models) and ensure it is maintenance-free and fits the OEM tray.
How to identify the correct battery for your Foreman 500
Before buying a replacement, confirm the exact group size and terminal arrangement on the battery currently in your Foreman, or consult the year-specific parts fiche. Use the steps below to verify compatibility:
- Check the battery label for the group size (for example, YTX14-BS or YTX12-BS) and the terminal orientation.
- Measure the battery tray space (length, width, height) to ensure a proper fit.
- Match the cable harness connections and terminal positions with the new unit.
Concluding: Matching the exact group size from the existing battery or the official service documentation is the safest way to ensure fitment.
Replacement options
There are OEM Honda batteries and aftermarket equivalents. Here’s what to know when choosing a replacement:
- OEM: Honda-branded 12-volt maintenance-free battery designed to fit the Foreman 500; most years use the YTX14-BS group size. Confirm the exact part number in your owner's manual or parts fiche.
- Aftermarket: Reputable brands such as Yuasa, Maxima, and Deka/Delcity offer YTX14-BS (or compatible) batteries that fit the Foreman 500. Ensure the replacement matches the group size and terminal layout.
Concluding: Select a battery with at least the same capacity and the correct terminal arrangement, and verify fitment in the battery tray before installation.
Installation tips and maintenance
Proper installation and maintenance extend battery life and reliability. Consider these guidelines:
- Disconnect the negative terminal first, then the positive when removing the old battery; connect positive first, then negative when installing.
- Ensure clean and tight terminals; apply a light coating of dielectric grease to prevent corrosion.
- Keep the battery charged, especially if the ATV sits for extended periods; use a smart charger suitable for motorcycles/ATVs.
- Inspect cables and connections periodically for wear or corrosion and replace as needed.
Concluding: Correct installation, secure mounting, and regular charging help maximize the Foreman 500’s battery life.
Summary
For most Honda Foreman 500 models, expect a 12-volt maintenance-free sealed lead-acid battery, commonly in the YTX14-BS group size. Always verify the exact group size with the current battery, owner’s manual, or parts fiche for your year. When replacing, choose a battery with equivalent or higher capacity and the correct terminal layout, and follow proper installation and charging practices.
