What Battery Fits a 2007 Honda Rancher 420?

The 2007 Honda Rancher 420 uses a 12‑volt, maintenance‑free AGM battery in the YTX12‑BS size (approx. 10 Ah, 180–200 CCA). This fitment applies to most TRX420 variants from that year, including 2×4/4×4 and manual/ES models, and is widely available under multiple brand-cross references.

Key Specifications and Fitment Details

For owners replacing the OEM unit or confirming a compatible aftermarket option, the following specifications are generally accepted for the 2007 TRX420 Rancher platform.

• Battery type: AGM (Absorbed Glass Mat), sealed/maintenance‑free
• Size code: YTX12‑BS (common equivalents: CTX12‑BS, GTX12‑BS, PTX12‑BS, ETX12, MBTX12U)
• Voltage/Capacity: 12V, ~10 Ah
• Cold Cranking Amps (CCA): typically 180–200 CCA (varies by brand)
• Dimensions (approx.): 150 x 87 x 130 mm (5.9 x 3.4 x 5.1 in)
• Chemistry: Lead‑acid AGM, spill‑proof

These specifications match the battery tray and electrical needs of the 2007 Rancher 420 across trims, delivering reliable starting performance and durability for ATV use.

Trim Variations and Compatibility

Honda’s 2007 Rancher 420 lineup (TRX420TM/TE for 2×4, TRX420FM/FE for 4×4, with manual or ES shifting) shares the same battery footprint. While accessories or winches can increase power demands, they do not typically change the required form factor. If heavily accessorized, you can choose a higher‑CCA AGM within the YTX12‑BS size.

AGM vs. Other Options

While AGM is the standard and most reliable choice for this ATV, some riders consider alternatives. Here’s how they compare so you can select the best option for your use and climate.

• AGM (recommended): Robust, maintenance‑free, vibration‑resistant, dependable across temperatures.
• Gel: Also sealed, but generally offers no advantage over AGM for ATVs and can be fussier with charging.
• Lithium (LiFePO4): Light weight and high CCA; requires compatible charging profile and can be sluggish in very cold weather; ensure it’s a YTX12‑BS drop‑in size.

Most Rancher owners stick with AGM for durability and hassle‑free charging with the stock system; lithium can be a good upgrade for weight savings if you ride in moderate climates and use a lithium‑compatible charger.

Factory-Activated vs. Acid Pack Units

Retailers sell YTX12‑BS batteries in two ways. Understanding the difference helps you get up and running quickly and safely.

• Factory‑activated AGM: Pre‑filled and sealed; install and ride.
• Acid‑pack AGM: You add the supplied acid and seal it before the first charge; follow instructions carefully and perform an initial charge for best life.

If you want the fastest, cleanest install, choose factory‑activated. If you’re comfortable with prep, acid‑pack units can be cost‑effective when properly filled and charged.

Practical Tips for Buying and Installing

Before purchasing, a few checks will ensure a perfect fit and smooth installation.

• Measure your current battery or tray to confirm YTX12‑BS dimensions.
• Verify terminal orientation matches your original unit.
• Check CCA rating if you run a winch or added lighting; aim for the upper end of the YTX12‑BS range.
• Fully charge the new battery before first use, even if it is “ready to go.”
• Clean and tighten terminals; apply dielectric grease to combat corrosion.

A quick pre‑install check prevents fitment surprises and maximizes starting performance, especially in cold weather or with added electrical loads.

Bottom Line

A 2007 Honda Rancher 420 takes a 12V AGM, maintenance‑free battery in the YTX12‑BS size (about 10 Ah, 180–200 CCA). Choose a reputable AGM unit—factory‑activated for convenience or acid‑pack if you prefer to prep it—and you’ll have the correct fit and reliable performance for your ATV.

Summary

The correct replacement battery for a 2007 Honda Rancher 420 is an AGM, sealed YTX12‑BS (or equivalent cross‑reference), typically around 10 Ah and 180–200 CCA. This size fits all main 2007 TRX420 trims, offers strong vibration resistance, and is the most dependable match for the stock charging system. Lithium drop‑ins exist but require compatible charging and are more sensitive to cold conditions.
