If high power is top priority in a replacement battery look to Yuasa’s High Performance Maintenance Free batteries. Yuasa means more power less maintenance and longer life. Yuasa’s High Performance Maintenance Free batteries are your best choice for motorcycles utility vehicles scooters ATVs ride-on mowers personal watercraft and snowmobiles.

All of the features of standard Maintenance Free batteries PLUS Increased Power – Up to 30% more cranking amps thanks to a radial grid design and additional plates.

Yuasa Cross Section Image



  • Spill-proof design means virtually no possibility of leaks
  • Advanced lead-calcium technology pumps up starting power
  • Sulphation retardant dramatically reduces battery-killing plate sulphation
  • Long lasting which means Yuasa’s High Performance Maintenance Free batteries will last up to three times longer than conventional batteries
  • Exceptional resistance to vibration makes Yuasa the most reliable battery on the market today
  • VRLA batteries hold voltage longer and need less charging in standby or storage mode

Cast Grid 

Special Grid Design 

Severe vibration resistance & improved conductivity 

Active Material 

Proprietary Formulation 

Reduced shedding maximum utilisation & long service life 

Pasted Plates 

Specified Thickness & Weight 

Ensures vibration resistance through precise compression & proper service life through specified active material balance 

Dry-Charged Plates 

Tank Formed & Dried Plates 

Properly dried plates in a sealed battery have a virtually limitless shelf-life while still retaining 70-80% state of charge when initially filled with acid 

Top Lead Connections 

Through-Partition Construction Large Straps 

Shorter current path for increased electrical conductivity & higher starting currents heavier parts for maximum durability 

Case-Cover Seal

Thermal Bonded Plastic 

Air tight seal to prevent air ingress & acid seepage 

Terminal-Cover Seal 

Patented Poly-Seal Terminal 

Eliminates acid seepage reduces corrosion & extends battery life 

Case & Cover 


Superior resistance to gasoline & oil impact resistant in extreme
weather conditions


Sulphate Stop (Some models) 

Sulphate stop added to reduce the solubility of lead into the acid which then reduces battery sulphation potential 



Leaf or Envelope Separator 

Polyethylene with glass mat sheet bonded for compression to withstand severe vibration conditions 



Absorbed Glass Mat 

Absorbs acid while creating cell compression for extreme vibration resistance 

Top Lead Alloy 

Calcium Alloy

Increased weld strength & severe vibration resistance 

Vent System 

Valve & Flame Arrestor 

Valve relieves excess pressure to prevent bursting flame arrestor prevents internal combustion

High Performance Maintenance Free

Grid System 

Computer-Designed Radial Grids 

Increased conductivity for higher starting wattage increased vibration resistance
