The Cortex Handsets (H1, H1P) include a Lithium Polymer battery,
- 2 hour full charge
- ~10 hours nominal operation (depending on speaker and screen usage)
Power consumption of the H1P when in the cradle is dependent upon the state of charge of the battery. If the battery is almost empty, then it can consume ~700 mA on 12V DC. The battery will continue to charge when the H1P is switched off using Sleep or Shutdown.
The H1 includes a battery to allow for fast boot times when it is placed in low power mode and disconnected from its power source, for example over night when not in use and its switched off at the breaker.
The power consumption will be neglectable when the battery has charged and the Handset is switched off.
