#1 · Best Overall

1. AJC TRX420FA2 Replacement

• Voltage: 12 V
• Compatible with Vehicle Type: ATV

Best for: Rancher 4×4 model-specific fit.

Why it ranks #1: Names the TRX420FA2 FourTrax Rancher directly, lists 200 CCA and 12-month coverage, and says it arrives sealed, charged, and ready.

AJC names the TRX420FA2 FourTrax Rancher 4×4 and model years 2014–2019, enabling a more targeted match for owners of that specific ATV. Factory activation means it arrives sealed and charged, while maintenance-free AGM construction avoids adding acid or water during setup.

The 200-CCA rating and 12-volt specification provide useful electrical comparison points, and the stated positive/negative polarity and B terminal identify connection details for installation planning. AJC describes the battery as an exact OEM replacement for the named TRX420FA2 and says its high-impact PP case resists vibration, a practical feature for off-road use. It also replaces several listed battery designations, but the model-year range remains specifically stated as 2014–2019 for this Rancher application.

Skip it if you own a different Rancher configuration or model year; CB CHROMEBATTERY YTX14-BS lists a wider range of Honda models.

This is the targeted pick for owners of the listed TRX420FA2 FourTrax Rancher 4×4 from 2014–2019 who value factory activation and a vibration-resistant case. Its stated fit range is specific.

• Compatible with Vehicle Type: Powersports
• Dimensions: 3.43"D x 5.94"W x 5.79"H

Why it ranks #2: Specifies Honda 420CC TRX420 Rancher 4×4 fitment for selected model years, with 12V, 12Ah, 200 CCA, and stated dimensions.

SigmasTek specifies the Honda 420CC TRX420 Rancher 4×4 from 2007–2009, enabling a targeted replacement search for those model years. Its STX14-BS battery provides 12 volts, 12 Ah, and 200 CCA, giving owners concrete electrical figures alongside the stated application.

The 5.94-by-3.43-by-5.79-inch dimensions give buyers a physical comparison point, while the 200-CCA and 12-Ah ratings describe starting output and capacity.

The description also claims resistance to extreme freeze, heat, and vibration, relevant to changing ATV conditions. Its named Rancher fit is specifically 2007–2009 4×4, so owners outside that stated range should not treat it as a universal Rancher match.

Skip it if you own a later Rancher 4×4; AJC TRX420FA2 FourTrax Rancher lists 2014–2019 fitment.

Choose this for a 2007–2009 Honda TRX420 Rancher 4×4 owner seeking stated capacity, CCA, and sealed AGM construction. Its fit information is specific to those years and drivetrain.

Why it ranks #3: Lists Rancher 420 among compatible models and provides 200 CCA, 12 volts, dimensions, and an 18-month warranty for U.S. orders.

A sealed, rechargeable AGM construction is the defining feature here, enabling spill-resistant use across a broad range of listed vehicles. CB CHROMEBATTERY also specifies 200 CCA and gives exact dimensions, so Rancher owners can compare starting output and physical measurements rather than relying only on the YTX14-BS name.

The 200-CCA rating and 12-volt specification give buyers concrete electrical figures, while the stated 5.91-by-3.39-by-5.71-inch dimensions help with a physical comparison before installation.

4. Mighty Max YTX14-BS260

• Voltage: 12 V
• Compatible with Vehicle Type: ATV
• Dimensions: 6"D x 3.44"W x 5.75"H

Best for: Named 2017 Rancher 2×4 fit.

Why it ranks #4: Its title specifically identifies the 2017 Honda TRX420 FourTrax Rancher 2×4, and specifications include 12Ah and 12 volts.

This Mighty Max listing names the Honda 420 TRX420 FourTrax Rancher 2X4 for 2017, enabling a narrowly targeted search for that exact application. Its 12-volt and 12-Ah specifications add basic electrical context, while the YTX14-BS designation identifies the replacement format.

The stated 6-by-3.44-by-5.75-inch dimensions help compare the battery case with the available compartment, and the 12-Ah capacity supplies a clear rating for evaluating alternatives. Mighty Max identifies ATV compatibility and explicitly names the 2017 Rancher 2X4 in the title, making the application unusually specific. However, the supplied product details do not state CCA, charging condition, or maintenance requirements, so buyers cannot assess those attributes from this listing alone.

Skip it if you own another Rancher model year or drivetrain; AJC TRX420FA2 FourTrax Rancher lists 2014–2019 4×4 fitment.

Best suited to owners of the specifically named 2017 TRX420 FourTrax Rancher 2X4 who want dimensions and capacity stated. Its listed Rancher application is narrower than a general model-family match.

5. Shotgun YTX14-BS

• Voltage: 12 V

Shotgun lists Honda TRX 420 alongside several other Honda ATV families, enabling one YTX14-BS replacement option across a broad stated range. The battery arrives charged, sealed, and maintenance-free, making its ready-to-install AGM format the central convenience for Rancher owners considering it.

Its 12-volt specification and 5.89-by-3.5-by-5.9-inch dimensions let buyers assess basic electrical requirements and compare the case with the available battery space. Sealed SLA/AGM construction is rechargeable and maintenance-free, so there is no routine acid or water addition listed. Shotgun names multiple compatible vehicle categories, including ATV, UTV, motorcycle, and snowmobile, and identifies Honda TRX 420 in the title. The supplied details do not state capacity or CCA, limiting electrical-output comparisons.

Skip it if you need capacity and CCA figures for a direct output comparison; Mighty Max Battery YTX14-BS lists 12 Ah and 200 CCA.

A practical option for Rancher owners valuing broad Honda ATV application wording and a sealed, maintenance-free format. Buyers who compare batteries by capacity or cranking output will find those figures unspecified.

6. Upstart UB-YTX14-BS-DL55

• Voltage: 12 V
• Compatible with Vehicle Type: ATV

Best for: Straightforward Rancher replacement.

Why it ranks #6: The title identifies a YTX14-BS replacement for Honda Rancher 420, and the specifications confirm 12 volts and ATV compatibility.

The YTX14-BS replacement is explicitly identified for the Honda Rancher 420, giving shoppers a direct model-family starting point rather than a broad powersports listing. Its 12-volt rating and ATV classification provide basic electrical and vehicle context for choosing a replacement, while the simple specification set keeps the focus on that stated application.

Upstart Battery lists this unit as a 12-volt battery compatible with ATVs and names the Honda Rancher 420 in the title. That combination makes it a focused option for owners seeking a Rancher-specific replacement rather than a battery described only for motorcycles or general powersports use. The supplied specifications do not give dimensions, capacity, or cold-cranking amps, so buyers cannot use those figures here to compare enclosure fit or starting output against their existing battery.

Skip it if you need stated dimensions or cranking output to compare before choosing; the listing does not provide those figures.

This suits a Rancher 420 owner prioritizing an explicitly named replacement and a 12-volt ATV battery. It is a less informative choice when dimensions or capacity are essential to your pre-installation comparison.

Its 5.90-by-3.42-by-5.70-inch dimensions help buyers compare the battery with the available compartment, while the left-positive, right-negative terminal layout supports connection planning.

A fit for Rancher riders prioritizing weather and vibration resistance with stated electrical figures and terminal orientation. The package lists the battery only, so account for any installation hardware you need.

Best for: Ready-to-install 200-CCA AGM.

Why it ranks #8: Lists 12 volts, 12Ah, 200 CCA, dimensions, and ATV compatibility, but does not provide specific Honda Rancher fitment.

Its 12-volt, 12-Ah capacity and 200-CCA rating give Rancher owners specific electrical figures to compare with their current battery.

The 12-Ah capacity and 200 CCA describe both stored capacity and stated cranking output, while the 6-by-3.44-by-5.75-inch dimensions help assess physical fit. Sealed SLA/AGM construction is spill-proof, and the listing notes wide operating temperatures and deep-discharge recovery, relevant qualities for an ATV used in changing conditions. It arrives charged and maintenance-free, but the package includes the battery and screws only; no wire harness or mounting accessories are included for installation.

Skip it if you need a wire harness or mounting accessories in the package; the listing includes only the battery and screws.

Choose this for a Rancher owner seeking a charged, maintenance-free AGM battery with stated capacity, cranking output, and dimensions. Plan separately for any harness or mounting accessories your installation requires.

• Voltage: 12 V
• Compatible with Vehicle Type: ATV, Motorcycle, Scooter, Snowmobile, UTV
• Dimensions: 3.43"D x 5.91"W x 5.71"H

Best for: Heat-resistant PP AGM battery.

Why it ranks #9: Provides a 12V, 12Ah AGM battery with dimensions and ATV compatibility, but the listing offers no specific Rancher model fitment.

UPLUS uses a polypropylene case that its listing says has better heat resistance, enabling a heat-focused material choice in a maintenance-free AGM battery. The 12-volt, 12-Ah specification and YTX14-BS designation give Rancher owners clear electrical and replacement-format details to compare.

The 5.91-by-3.43-by-5.71-inch dimensions and 12-Ah capacity support practical comparison of compartment space and battery rating. UPLUS describes the battery as a 12-volt AGM unit with maintenance-free operation, so owners avoid routine fluid maintenance. Its PP case is stated to have better heat resistance, and the listing includes ATVs among compatible vehicle types. A stated [+,-] polarity provides an additional connection reference, though the supplied facts do not give a cold-cranking-amp figure.

Skip it if you need a listed CCA figure to compare starting output; Weize YTX14 BS specifies 200 CCA.

This suits Rancher owners looking for a maintenance-free AGM battery with stated dimensions and a heat-resistant PP case. If comparing cranking output is central, its listing leaves CCA unspecified.

• Compatible with Vehicle Type: ATV, Cruiser/ Touring, Dirt Bike, Street…
• Dimensions: 6"D x 3.48"W x 5.8"H

Best for: Multi-vehicle sealed replacement.
