Personal watercraft snowmobiles and ATVs make special demands – and YUASA’s YuMicron Battery meets them head-on. The high-tech power-boosting design also makes YuMicron ideal for accessory-laden touring bikes and modified vehicles.



  • Heavy duty glass mat resists vibration damage
  • Special thin Separator packs in extra plates delivers up to 30% more cranking power than conventional types
  • Through-the-wall intercell connector minimises internal resistance maximises power
  • Sulphate Stop curbs plate sulphation – and provides longer life

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
