The Mighty Max Battery YTX30L-BS is a sealed 12‑volt, 30 Ah AGM rechargeable battery delivering 385 CCA in a maintenance‑free, ready‑to‑install package for motorcycles, ATVs, PWC and similar powersports vehicles.

This high‑rate sealed lead‑acid battery uses absorbed glass mat (AGM) construction to combine spill‑proof reliability, strong cold‑cranking performance and wide temperature tolerance. It ships charged and sealed so you can install it right away without adding electrolyte or carrying out regular maintenance. Built for vibration resistance and reversible mounting, the YTX30L‑BS is a practical replacement battery for many small‑engine and powersports applications.

Will this battery fit my motorcycle or ATV?

The YTX30L‑BS follows compact dimensions and a common terminal layout used by many powersports OEMs. Verify your vehicle’s required battery group and polarity before ordering to ensure compatibility.

• Physical size: 6.60" (length) x 4.96" (width) x 6.88" (height)
• Polarity: positive terminal on the right, negative on the left
• Typical fit: motorcycles, ATVs, personal watercraft, jet skis, snowmobiles
• Replacement note: sold as battery plus terminal screws only; no harness or mounting brackets included

How does AGM construction benefit powersports use?

AGM (absorbed glass mat) traps electrolyte in fiberglass mats, making the battery spill‑proof and tolerant of different mounting orientations. That construction also supports higher discharge rates and better vibration resistance than conventional flooded batteries.

• Spill‑proof and sealed for safe installation in varied positions
• High discharge capability supports starting and accessories
• Resists shocks and vibration typical of off‑road use
• Performs across a wide temperature range for seasonal use

What electrical performance can I expect from the YTX30L-BS?

This model is rated at 12 volts with a 30 amp‑hour capacity and 385 cold cranking amps (CCA), providing reliable starting power for small engines and enough reserve for lights and accessories. It’s rechargeable and engineered for repeated deep discharge recovery.

• Nominal voltage: 12 V
• Capacity: 30 Ah for medium‑duration loads
• Starting power: 385 CCA for cold starts
• Rechargeable SLA/AGM chemistry for long service life with correct charging

How do I install and maintain this battery safely?

The unit arrives fully charged and sealed, so installation is straightforward: secure the battery, attach the terminals in the correct polarity, and tighten the supplied screws. Regular maintenance is minimal—keep terminals clean and use a compatible charger to maintain long service life.

• Install upright or in other supported orientations as space allows
• Always connect positive terminal first, then negative when installing
• Use a charger compatible with sealed AGM batteries for storage charging
• Inspect terminals for corrosion and tighten screws to recommended torque

Who is this for? The Mighty Max YTX30L‑BS suits riders, racers and powersports owners who need a maintenance‑free, robust battery with solid cold‑cranking ability and resilience against vibration and temperature swings. It’s ideal as a factory replacement or upgrade for motorcycles, ATVs, personal watercraft and snowmobiles when you want a sealed, rechargeable battery that’s ready to install and covered by a one‑year warranty.
