Pirate Battery YTX4B-BS 12V AGM Scooter & Mini ATV Battery, 2 Ah 40 CCA — Sealed Maintenance-Free

Pirate Battery YTX4B-BS is a compact, sealed 12 V AGM starter battery delivering maintenance-free power for scooters, pocket bikes and youth ATVs.

This compact YTX4B-BS battery combines absorbed glass mat (AGM) technology with a sealed, spill-proof design so you can swap it into small vehicles without periodic topping up. Ship‑ready and precharged, it is sized to replace many factory batteries found in lightweight motorcycles and scooters while offering protection against vibration and orientation changes. The battery is rated at 40 cold cranking amps (CCA) and 2 amp-hours (2 Ah), making it a reliable option for cold starts and short run use in personal transport and recreational vehicles.

Will this battery fit my small scooter or mini ATV?

Measure space and terminal orientation before ordering. The YTX4B-BS follows a compact footprint commonly used in scooters and youth ATVs; its dimensions are 4.45 in (length) x 1.54 in (width) x 3.43 in (height). It uses a top-facing tab terminal that fits many Yamaha Zuma, Honda Metropolitan, and similar models, but always compare dimensions and terminal type to your OEM battery.

• Physical dimensions: 4.45" L x 1.54" W x 3.43" H
• Terminal style: top tab terminals suitable for common small vehicle adapters
• Direct replacements: matches many YTX4B-BS OEM slots
• Tip: verify cable length and bracket clearance before installation

How reliable is the battery in daily use and rough conditions?

Built as a sealed AGM unit, this battery resists leaks and can tolerate moderate vibration and movement — typical demands for scooters, pocket bikes and entry-level ATVs. Because it is sealed, there’s no electrolyte to check or add, and the AGM construction provides stable performance during short rides and frequent start cycles. It is assembled to meet strict quality-control benchmarks and carries UL safety certification to help ensure consistent behavior in usual use cases.

• Sealed AGM design prevents spills and reduces maintenance
• Vibration-resistant construction for small off-road and street use
• UL safety certification and tight quality control standards
• Works well for frequent short trips and seasonal storage

Do I need any special tools or prep to install it?

No special equipment is required for a standard swap. The Pirate Battery arrives charged and ready to connect; installation typically involves removing the old battery, securing the new unit in the bracket, and fastening the tab connectors to the correct terminals. Follow polarity markings, tighten connectors snugly, and if the vehicle has a crumb tray or cover, ensure clearance for the top tabs.

• Arrives precharged — ready for immediate installation
• Standard hand tools (wrench/screwdriver) usually suffice
• Observe polarity and torque recommendations for terminals
• Keep battery upright during installation to protect connectors
