Useful Tips

  • Try setting Voltage one lower than your laptop charger's output first. i.e. if your charger says 19V, try 16V setting on Voltaic battery first. This saves power.
  • This battery will work best with smaller, more efficient laptops
  • Change your power management settings to Maximum Battery Life & Turn off WiFi
  • Some laptops will run from the Voltaic battery with their internal battery removed. You should turn off your laptop before the Voltaic battery is fully drained to avoid crashes.
  • Remove the cable from your device before changing Voltage between 12, 16 and 19Volts.
  • We recommend storing and charging the battery in a cool place.
  • If you don't see the correct adapter for your device, please use the manufacturer supplied USB cable or please contact us via email or call us.
