The SafeDistance Badge is designed to have a battery autonomy, under normal working conditions, of about at least a full working day. If the battery level goes below 20%, it will beep to remind the user to charge it. Press the button once to turn off the beeping. The beeping does not resume after the button has been pressed.
- When battery level is between 20%~100%, normal operation.
- When battery level is between 10%~20%, it beeps once per two minutes.
- When battery level is between 5%~10%, shutdown Proximity Detection, continue to transmit BLE beacon messages, send battery alarm to Dashboard.
- When battery level is less than 5%, the badge will be powered off automatically in order not to damage the battery.
The battery capacity begins to drop after 500 times of full charge. It is recommended however to regularly completely drain the Badge's battery by keeping it powered on untill it shuts down automatically. (at least once per month)
The table below gives an overview of the to expected lifetime of a badge on a single battery charge.
The first 2 rows are performed with badges in close proximity (with beeping an vibration on), with DFU mode on.
The second 2 rows are performed with 2 badges in "safe distance", so not detecting each other.
The last 2 rows are with badges in close proximity (with beeping an vibration on), but with DFU mode off.
Badge in close proximity?
(*) DFU mode can be enabled from the SafeDistance Portal upon request to your SafeDistance System Integrator point of contact. It can be used to allow Delta Firmware Upgrade (hence DFU) your badges with a different firmware version.
