Traffic Calming Sign Battery Life Calculator
Note: At the moment this only works with Firefox browser!
This simple on-line calculator will help you estimate the expected battery life you'll typically get from your sign.
As inputs you'll need:
1. The power usage of your display panels at full brightness (max sunlight) (in watts or Amps)
2. The power usage of your display panels at minimal brightness (nighttime) (in watts or Amps)
3. The power usage of your display panels (or controller) with LED dark (in watts or Amps)
4. The power usage of the radar you plan to use (we've filled in the value for the DR500S radar)
5. The average traffic density on the road during the day and at night (vehicles/hour)
6. The size of the battery you plan to use in amp hours. This is usually in the range of 25 to 40Ah for pole mounted signs or portable signs and typically 200 to 400Ah for trailers
7. The average speed of the traffic on the road (in MPH)
Finally if you would like to compare the battery run time with another radar, please enter the value. We've also put in a default to guide you.
8. The power usage of a competing radar in watts or Amps (accept default to compare with a typical competing radar in the market).
