YTX20HL-BS 12V 310 CCA AGM Battery for ATV Motorcycle - Reliable

In this review of the YTX20HL-BS battery the bottom line is simple: this sealed AGM battery is aimed at riders and powersports owners who need dependable, maintenance-free starting power across ATVs, UTVs, motorcycles and watercraft. The biggest reason to buy is its high-output design and ready-to-install condition; the battery ships fully charged and delivers strong cranking performance for machines like the Polaris Sportsman, Yamaha Grizzly, and Harley Electra Glide, making it a practical replacement for many factory units.

Key Features

• Sealed AGM construction: Spill-proof, vibration-resistant design keeps electrolyte contained and reduces maintenance demands in off-road and marine use.
• High cranking output: 310 CCA provides strong starting power for a wide range of small engines and larger displacement bikes and ATVs.
• Ready to install: Batteries arrive fully charged so users can connect and start their machine without lengthy charging routines.
• Compact dimensions: At about 6.97in x 3.46in x 6.1in the battery fits many OEM trays where space is limited.
• Warranty and support: 18 month warranty for U.S. orders plus a 60-day refund policy and U.S.-based customer service from battery experts.
• Safety and quality: Built to strict Japanese QC standards and UL-certified for safety, providing reassurance for everyday use.

Who It's For

The YTX20HL-BS is best for owners of ATVs, UTVs, dirtbikes, scooters, jet skis and larger motorcycles who need a maintenance-free, high-output replacement battery that fits common top-terminal trays and accepts T3 nut & bolt terminals. It is especially suited to riders who value a sealed AGM unit that arrives ready to use and can tolerate vibration and occasional wet conditions.

Those who should look elsewhere include users who need a battery with extended deep-cycle capacity for long standby use, or buyers outside the U.S. looking for warranty coverage, since the stated warranty applies to U.S. orders only. Also consider a different chemistry or higher-capacity model if you require multi-year deep-discharge riding schedules.
