On a full charge, the rechargable LI-ION backup battery will keep an EFIS on for 2 hours. Any time the EFIS loses its primary power, a message is instantly posted on the screen to alert the pilot that the instrument will be shutting down within 30 seconds unless further action is taken. A simple press of any button on the instrument continues operation on battery power.
The Backup Battery can be used on the following Dynon EFIS Displays: – EFIS-D10A – EFIS-D100 – FLIGHTDEK-D180
