Mighty Max Battery 12V 3Ah YTX4L-BS SLA ATV Battery — Compact Sealed AGM, 50 CCA, Vibration-Resistant

This battery delivers dependable electrical power in a small package for 50–125cc off-road bikes and similar light vehicles. Built as a sealed lead-acid (SLA) / AGM design, it resists spills, tolerates a wide temperature range, and recovers well after deep discharge events. The YTX4L-BS balances compact dimensions, vibration resistance and a maintenance-free sealed construction to suit rugged, active riding conditions.

What are the key specifications and physical details?

The YTX4L-BS is a 12-volt battery rated at 3 amp-hours with 50 cold-cranking amps (CCA), sized to fit many small-displacement bikes. Polarity places the negative on the left and the positive on the right when the terminals face you. The battery measures 4.40" x 2.90" x 3.42", and this listing includes the battery and terminal screws only.

• Voltage: 12V; Capacity: 3Ah; CCA: 50
• Dimensions: 4.40" x 2.90" x 3.42" (L×W×H)
• Polarity: negative terminal on left, positive on right
• Contents: battery and screws (no harness or mounting brackets)

How does this battery handle demanding riding conditions?

As a sealed AGM-type SLA battery, the YTX4L-BS tolerates vibration and high-discharge demands typical of off-road use. Its construction allows mounting in multiple orientations and improves durability against shocks. The design also supports operation across a broad temperature range without liquid leakage.

• SLA/AGM sealed for spill-proof operation and versatile mounting
• High discharge capability for reliable starting under load
• Durable against vibration and shock during off-road riding
• Performs in both hotter and colder ambient temperatures

What maintenance and charging practices should I follow?

The battery arrives sealed and maintenance-free, so regular water checks are not needed. Keep it charged with a compatible 12V charger after long storage or heavy use to extend service life. Avoid prolonged deep discharge; while the battery recovers from deep discharge events better than some designs, consistent shallow cycling preserves capacity.

• Use a 12V compatible charger designed for SLA/AGM batteries
• Recharge after extended storage or after deep discharge episodes
• Store charged in a cool, dry place to reduce self-discharge
• Do not expect external mounting hardware—use appropriate clamps or trays

What warranty and included parts come with the purchase?

This YTX4L-BS is backed by a full one-year warranty from the manufacturer, covering defects in materials and workmanship under normal use. The package contains the battery and terminal screws; wiring harnesses, straps, or mounting plates are not provided, so plan to reuse existing hardware or acquire suitable mounting accessories.

• Manufacturer warranty: one year
• Included: battery and terminal screws only
• Excluded: harnesses, straps, or battery trays/mounts
• Check polarity before installation to prevent electrical damage

Who is this for: Riders, mechanics, and hobbyists seeking a compact, sealed replacement battery for 50–125cc ATVs, quads and dirt/pit bikes will find the Mighty Max YTX4L-BS a practical option. It suits users who need a vibration-resistant, maintenance-free battery with clear dimensions and polarity, plus a one-year warranty for peace of mind. If you require additional mounting hardware or harnesses, plan to source those separately to complete installation.
