Mighty Max Battery 12V 30Ah AGM Motorcycle Battery YTX30L-BS – 385 CCA, Maintenance-Free

The Mighty Max Battery YTX30L-BS is a sealed 12-volt, 30 amp-hour AGM motorcycle battery delivering 385 CCA in a maintenance-free, ready-to-install package.

Built with absorbed glass mat (AGM) technology, this YTX30L-BS replaces conventional wet cells with a sealed, spill-proof design that arrives charged and primed for use. Its construction offers high discharge capability, resistance to vibration, and reliable performance across a wide temperature range, making it suitable for motorcycles, ATVs, jet skis, snowmobiles and other powersport vehicles. The unit ships with terminal screws and includes a one-year limited warranty.

What are the key specifications and physical dimensions?

The YTX30L-BS is specified as a 12V, 30Ah sealed lead-acid battery rated at 385 cold cranking amps (CCA). It follows the common YTX30L-BS footprint so it fits many OEM trays and mounts used in powersports applications.

• Voltage: 12 V; Capacity: 30 Ah; Cold Cranking Amps: 385 CCA
• Dimensions: 6.60" (length) x 4.96" (width) x 6.88" (height)
• Polarity: positive terminal on right, negative on left
• Includes battery and terminal screws only; no harnesses or mounting plates

How does AGM technology benefit powersport vehicles?

AGM construction traps electrolyte in fiberglass mats, creating a sealed, spill-proof cell that tolerates vibration and can be mounted in multiple orientations. This design provides higher discharge rates than typical flooded lead-acid batteries and improves recovery after deep discharge events.

• Spill-proof sealed design reduces maintenance needs
• High discharge capability supports strong starting performance
• Resists shocks and vibrations common in off-road use
• Works reliably in a wide range of temperatures

What should I know about installation and maintenance?

The battery arrives charged and sealed, ready to install without adding electrolyte or venting. Use the supplied screws to secure the posts and follow your vehicle manufacturer’s torque recommendations; no special tools or conditioning are required for normal use.

• Comes pre-filled, charged and maintenance-free—no topping up
• Can be mounted in any position, but follow vehicle fitment guidance
• Use an appropriate charger for AGM batteries when recharging
• Disconnect and store charged battery during long-term non-use to prevent deep discharge

What warranty and safety considerations apply?

Mighty Max Battery backs this model with a one-year warranty covering manufacturing defects. As with all lead-acid batteries, handle with care: avoid shorting terminals, dispose of properly, and use recommended chargers designed for sealed AGM chemistries.

• One-year limited warranty from the manufacturer
• Sealed design minimizes risk of spills but still requires safe handling
• Use an AGM-compatible charger to prevent overcharging
• Recycle or dispose of spent battery according to local regulations

Who is this for: The Mighty Max YTX30L-BS is aimed at riders and powersport owners who need a dependable, maintenance-free replacement battery with strong starting power and rugged performance. It suits owners of motorcycles, ATVs, personal watercraft, jet skis and snowmobiles who want a sealed AGM battery that withstands vibration, accepts high discharge loads, and installs without special preparation.
