The YTX5L-BS Maintenance Free AGM Battery is engineered as a premium, high-calibre power system optimised to suit the latest high-performance motorcycles, ATVs, and personal watercraft. Precision-built to deliver elite reliability under punishing Australian climate variations, this advanced Absorbed Glass Mat (AGM) battery provides an exceptional balance of prompt cranking power and structural stamina out of a compact frame. Featuring a fully factory-sealed design, it completely minimises internal fluid evaporation and eliminates ongoing maintenance tasks, ensuring your machine is always primed for adventure.
Perfect for drivers who demand:
- ✓ Up to 30% more initial cranking amps to fire up modern high-performance engines instantly
- ✓ Superior impact and vibration armour built to handle rough off-road trails and marine corrugations
- ✓ A premium spill-proof configuration that delivers total driving convenience with zero fluid top-ups
Key Features & Benefits
Advanced Radial Plate Design
- • Specialist internal grid geometry delivers up to 30% more cranking performance than conventional units
- • Extra internal battery plates expand active grid surface area for instantaneous starting energy
- • Optimises electrical output and flow over a long working service life in local climates
Sealed Maintenance-Free Cover
- • Fully sealed layout successfully limits premature electrolyte fluid evaporation and vapour loss
- • True "install and forget" design completely avoids the need for regular distilled water top-ups
- • Spill-proof casing architecture enables secure installation at multi-angle positions without leakage
Vibration & Impact Armour
- • High puncture-resistant AGM separators smoothly absorb continuous kinetic trail shocks
- • Robust case structure protects delicate internal components from structural stress fractures
- • Greatly extends operational longevity under intense off-road, highway, and marine vibrations
Sulphation Retardant Technology
- • Premium chemical additives help curb internal plate damage during extended seasonal downtime
- • Retards crystal build-up to maintain excellent voltage retention over long storage intervals
- • Restores full electrical charging efficiency more quickly when modern smart chargers are attached
Advantages & Considerations
Advantages
- ✓ Generous 24-month local warranty coverage for peace of mind
- ✓ Reliable 80 CCA starting capability optimised for compact powersport setups
- ✓ Inbuilt anti-sulphation barriers preserve plate health through the winter months
- ✓ Factory-sealed Absorbed Glass Mat profile ensures absolute spill protection
Considerations
- • Compact 4 Ah output is dedicated to starting engine loads, not large auxiliary accessories
