Installation Instructions

When removed from packaging

  • Ensure fully charged VRLA 2.0Ah VRLA battery ie more than 12.5V
  • Connect the terminals of the 2.0 Ah VRLA battery with proper polarity as mentioned on the battery
  • Place the 2.0 Ah VRLA battery in the ULTRA-capacitor Unit
  • Clean the battery termninals,remove precipitaion / sulfphation due to acid

On the Vehicle

  • Place Hybrid battery in the space provided on the vehicle.
  • Connect vehicle wires to the 2.5Ah Ultracapacitor terminals with correct polarity and fasten the nuts.
  • Start the vehicle and increase the throttle(accelerator) to 70% and wait for minute.


Ensure correct polarity (+/-). Do not short terminals.
No Distilled water required. Initial Charging is not required.
For AC-CDI engines only. Do not use for DC-CDI. Use of multiple horns may trigger over voltage indicator.
