What type of battery is in a Honda Rancher?

A Honda Rancher uses a 12‑volt, sealed AGM (Absorbed Glass Mat) powersports battery. Most Rancher 420 models take either a YTX14‑BS or YTZ14S size depending on the year, while earlier Rancher 350 models typically use a YTX12‑BS. Because Honda made running changes across generations, the exact fitment can vary—so it’s best to confirm with the owner’s manual or OEM part number.

The standard battery type

Across its generations, the Honda Rancher line is designed around maintenance‑free AGM batteries. AGM cells are sealed, spill‑proof, tolerate vibration well, and hold charge reliably—attributes that suit ATV use in mud, dust, and cold weather. While lithium (LiFePO4) replacements exist and can be good upgrades, the factory specification is AGM unless otherwise noted in your manual.

Common OEM sizes by Rancher generation

The exact battery case size used in a Rancher depends on model year and displacement. The following list outlines the sizes most commonly specified by Honda and widely used in the aftermarket for each generation, but owners should verify the label on the existing battery tray or the official parts fiche for their VIN.

• Rancher 350 (TRX350, approximately 2000–2006): YTX12‑BS (AGM), about 12V/10Ah, ~180–200 CCA.
• Rancher 420 (TRX420, 2007–2013): YTX14‑BS (AGM), about 12V/12Ah, ~200–230 CCA.
• Rancher 420 (TRX420, 2014–present): YTZ14S (AGM), about 12V/11.2Ah, ~230–270 CCA. Some trims and dealers also supply YTX14‑BS; certain trays use a spacer to accommodate the shorter YTZ14S case.

These fitments cover the vast majority of Rancher models on the trail today. Electronic shift (ES), fuel‑injected (EFI), and DCT/AT variants typically share the same battery size within each generation, but double‑check your specific model year to avoid surprises.

Key specs to check

Even if you know the case size, confirming a few core specifications ensures proper cranking performance and fit. The items below are the essentials to match when replacing your Rancher battery.

• Voltage: 12V (all Rancher models).
• Chemistry: AGM (sealed, maintenance‑free) is OEM; LiFePO4 (lithium) is an optional upgrade if sized correctly and used with a compatible charger.
• Capacity (Ah): Typically 10–12Ah depending on size (YTX12‑BS ≈ 10Ah, YTX14‑BS ≈ 12Ah, YTZ14S ≈ 11.2Ah).
• Cold Cranking Amps (CCA): Common ranges are ~180–270A; higher CCA helps in cold starts and with accessories like a winch.
• Dimensions (L × W × H, mm):
  – YTX12‑BS: ~150 × 87 × 130
  – YTX14‑BS: ~150 × 87 × 145
  – YTZ14S: ~150 × 87 × 110
• Terminal layout/polarity: Match the original battery’s post orientation to avoid cable strain and misconnection.

Matching these details will ensure the replacement slides into the tray, clamps securely, and delivers the cranking power the Rancher expects.

Replacement and care tips

Proper selection and upkeep can significantly extend battery life, particularly if the ATV sits between seasons. The following steps help ensure reliable starts and safe charging.

1. Verify the part number against your owner’s manual or an OEM parts fiche using your VIN before purchasing.
2. If buying a YTX‑series battery that is not factory‑activated, carefully fill with the supplied acid pack, let it rest per instructions, and fully charge before installation.
3. Use a smart charger/tender suitable for AGM batteries, ideally 0.8–2.0A; avoid high‑amp “boost” chargers.
4. Clean terminals, tighten hardware, and apply a light coat of dielectric grease; ensure the hold‑down secures the case to prevent vibration damage.
5. Considering lithium (LiFePO4)? Choose a model with the correct case size and built‑in BMS, confirm cold‑weather starting guidance, and use a lithium‑compatible charger.

Following these practices helps maintain capacity, prevents sulfation, and reduces the risk of electrical issues on the trail.

Summary

A Honda Rancher uses a 12V sealed AGM battery. Most Rancher 420s take either a YTX14‑BS (earlier years) or YTZ14S (2014–present), while older Rancher 350s commonly use a YTX12‑BS. Because fitment can vary by year and trim, confirm the exact size and specs with your owner’s manual or the OEM part number before you buy, and maintain it with an AGM‑appropriate charger for best results.
