1. Yuasa YTX20HL-BS: Best Overall
The Yuasa YTX20HL-BS is the OEM-spec battery for many Honda ATVs, including the Rancher 420. In our evaluation, its 270 CCA and 18Ah capacity provide strong starting power even in cold conditions. Owner feedback consistently highlights its reliability and long service life, often lasting 4-5 years. The AGM construction is spill-proof and vibration-resistant, making it ideal for off-road use.
However, this battery commands a premium over generic brands. If you are on a tight budget or need a battery only for occasional use, a less expensive option may suffice. But for riders who prioritize dependability and a perfect fit, the Yuasa is a top choice.
- Factory-recommended replacement for Honda Rancher 420
- Maintenance-free AGM design with spill-proof construction
- High 270 cold cranking amps for reliable starts in cold weather
Pros: Perfect fit and direct replacement; Excellent cranking power and long lifespan
Cons: Higher price than generic alternatives
2. Antigravity ATX-20-RS: Best Lightweight Lithium
The Antigravity ATX-20-RS is a premium lithium battery that offers a 60% weight reduction compared to lead-acid. With 540 CCA, it provides exceptional starting power. The integrated BMS ensures safe operation and protects against common lithium battery issues. Owner reviews praise its performance in cold weather and long standby life.
However, the high cost and need for a lithium-specific charger are drawbacks. If you do not need the weight savings or ride in extreme cold rarely, a conventional AGM battery may offer better value. This battery is best for enthusiasts who want the latest technology and are willing to pay for it.
- Lithium iron phosphate chemistry for extreme weight savings (about 4 lbs)
- Built-in battery management system (BMS) for overcharge and discharge protection
- 540 CCA for powerful cranking, even in cold weather
Pros: Very lightweight, reduces overall ATV weight; High cranking amps and fast recharge
Cons: Requires a compatible charger; expensive
3. Mighty Max ML18-12: Best Budget Pick
The Mighty Max ML18-12 is a budget-friendly AGM battery that offers comparable specs to the Yuasa at a fraction of the cost. In our evaluation, it delivers adequate starting power for the Honda Rancher 420, and many owners report satisfactory performance for everyday use. The sealed design prevents leaks and requires no maintenance.
However, some user feedback indicates a shorter service life, sometimes 2-3 years, and the build quality may not withstand heavy off-road vibration as well as premium options. If you ride frequently in rough terrain or need maximum reliability, consider spending more. For casual riders on a budget, this is a solid choice.
- Affordable AGM battery with specs similar to Yuasa
- Maintenance-free and spill-proof
- Fits many ATV and motorcycle applications
Pros: Very low price for an AGM battery; Decent cranking power for the cost
Cons: Shorter lifespan reported by some users; Not as vibration-resistant as premium brands
4. Odyssey PC680: High Performance AGM
The Odyssey PC680 is known for its rugged construction and long lifespan. Its pure lead plates provide superior vibration resistance and deep cycling capability, making it a favorite for off-road and racing applications. We found that its 270 CCA is sufficient for the Rancher 420, and owner feedback often highlights its reliability over many years.
One limitation is that the PC680 is slightly shorter and narrower than the OEM battery, so you may need to add foam padding or a shim to secure it in the battery tray. Additionally, it is more expensive than many AGM options. If you ride in extreme conditions and want a battery that can take a beating, this is a great pick. For casual use, the extra cost may not be justified.
- Pure lead AGM technology for high vibration resistance
- Long service life with up to 10 year design life
- High cycle durability for frequent starts
Pros: Extremely durable and vibration-proof; Excellent for demanding off-road use
Cons: Slightly smaller physical size may require shimming; Higher cost than standard AGM batteries
5. Chrome Battery YTX20HL-BS: Best Value AGM
Chrome Battery offers a direct equivalent to the Yuasa YTX20HL-BS with a slightly higher 280 CCA. In our research, this battery provides reliable starting power and fits perfectly without modifications. Owner reviews generally praise its performance for the price, making it a strong value pick.
However, we noted some reports of premature failure or defects, suggesting quality control may not be as consistent as top-tier brands. The 1-year warranty is shorter than Yuasa’s or Odyssey’s. If you want peace of mind and are willing to pay a bit more, a premium brand may be better. For budget-conscious buyers, this is a solid alternative.
- Direct replacement for Yuasa YTX20HL-BS
- 280 CCA slightly higher than OEM spec
- Maintenance-free with a 1-year warranty
Pros: Good performance at a competitive price; Easy drop-in installation
Cons: Inconsistent quality control per some reviews; Shorter warranty than some competitors
6. Weize YTX20HL-BS: Budget AGM Alternative
The Weize YTX20HL-BS is one of the most affordable AGM batteries available for the Honda Rancher 420. It offers the same 270 CCA and 18Ah rating as the Yuasa, and many owners find it works adequately for light to moderate use. The sealed design means no maintenance, and it comes with terminal bolts for easy installation.
However, we found that durability is a concern. Several owners report the battery failing after 1-2 years, especially in colder regions. The build quality does not match premium brands, and vibration resistance is lower. If you ride occasionally in mild climates and want to save money, this could work. For regular or demanding use, we recommend investing in a higher-quality battery.
- Low-cost AGM battery with standard specs
- Sealed and maintenance-free
- Includes terminal hardware
Pros: Very affordable price; Simple installation
Cons: Shorter lifespan reported by many users; Less reliable in cold climates
7. Duralst YTX20HL-BS: Entry Level Lithium
The Duralst YTX20HL-BS is an entry-level lithium battery that offers a weight advantage and decent starting power. With 400 CCA, it can handle the Rancher 420’s engine easily. The included BMS provides protection against overcharging and discharging. For riders looking to shed some pounds without spending a lot, this is a tempting option.
However, we found that durability and reliability are inconsistent. Some owners report the battery failing within a year or the BMS malfunctioning. The warranty is short, and customer support can be lacking. If you want the benefits of lithium but have a limited budget, this may be worth a try. But for dependable long-term use, a quality AGM or a premium lithium like Antigravity is a safer bet.
- Lithium chemistry for weight reduction (about 3 lbs lighter than lead-acid)
- 400 CCA provides strong starting power
- Built-in BMS for basic protection
Pros: Lightweight and compact; Good cranking amps for the price
Cons: Lower build quality and shorter lifespan than premium lithium; Some reports of BMS failure
Frequently Asked Questions
What type of battery is best for a Honda Rancher 420?
For most riders, a maintenance-free AGM battery like the Yuasa YTX20HL-BS is the best choice. It offers a perfect fit, reliable cold cranking amps, and good vibration resistance. Lithium batteries are lighter and provide higher CCA but cost more and require a compatible charger.
How do I know which battery size fits my Honda Rancher 420?
The Honda Rancher 420 typically uses a YTX20HL-BS size battery (dimensions approximately 6.9 x 3.4 x 6.1 inches). Always check your owner’s manual or measure the battery tray to confirm. Most aftermarket batteries listed as YTX20HL-BS will fit directly.
Can I use a lithium battery in my Honda Rancher 420?
Yes, you can use a lithium battery as long as it has the correct dimensions and CCA rating. However, lithium batteries require a smart charger designed for lithium chemistry. They also perform differently in extreme cold; some have built-in heaters or BMS that help, but not all.
How long should a Honda Rancher 420 battery last?
With proper maintenance, a quality AGM battery typically lasts 3-5 years. Lithium batteries can last 5-8 years, but their lifespan depends on usage and charging practices. Factors like extreme temperatures, frequent deep discharges, and vibration can shorten battery life.
What is the difference between AGM and standard lead-acid batteries?
AGM (Absorbent Glass Mat) batteries are sealed, spill-proof, and maintenance-free. They have lower internal resistance, which allows faster recharging and higher CCA. Standard flooded lead-acid batteries require periodic water checks and are more prone to leaking. AGM is the preferred type for ATVs.
