This YTX4L-BS sealed lead-acid (SLA) battery uses absorbed glass mat (AGM) construction to combine spill-proof safety with high discharge capability and vibration resistance. It ships fully charged and sealed, so it's ready to install in motorcycles, ATVs, personal watercraft, snowmobiles, and other small engine applications. The battery fits tight spaces while offering dependable cold-cranking performance and a full one-year warranty for peace of mind.

How does this battery perform in cold starts and short rides?

The YTX4L-BS provides 50 cold cranking amps (CCA), helping engines fire quickly in cooler conditions and after short rest periods. AGM chemistry supports strong bursts of current for starting while tolerating repeated shallow discharges common to short rides. It’s particularly useful when you need reliable starts without lengthy charging between trips.

• 50 CCA for dependable starts in cool weather
• AGM design sustains high discharge rates
• Performs well after short, frequent uses

Can I mount this battery in different positions and environments?

Yes — the sealed AGM construction is spill-proof and can be installed in virtually any orientation. The casing resists shocks and vibration, making it appropriate for off-road or marine use where movement and impact are expected. It also tolerates a wide temperature range typical of powersport and seasonal equipment.

• Mount in any position without leakage risk
• Vibration-resistant for rough terrain and marine use
• Wide operating temperature tolerance for seasonal storage

What are the physical specs and compatibility details?

The compact dimensions are 4.40" x 2.90" x 3.42", making the battery suitable for small battery compartments on scooters, motorcycles, ATVs, and jet skis.

How do I maintain and extend the life of this maintenance-free battery?

Although labeled maintenance-free, the battery benefits from periodic charging when stored long-term to prevent deep discharge. Use a compatible charger designed for AGM/lead-acid batteries and avoid leaving the battery fully discharged for extended periods. Proper charging and storage practices maximize cycle life and readiness for seasonal use.

• Use an AGM-compatible charger for best results
• Top up charge before long-term storage to avoid deep discharge
• Avoid leaving the battery completely drained for long periods
