## Battery runtime

- Prism Flex Mk II Encoder on a 50 Wh battery: about 2.5 h at typical draw (20 W), about 1.4 h at maximum draw (36 W). Workings: [/calc/battery-runtime.md?product=prod.prism-flex-mk-ii-encoder&wh=50](https://specs-dev.teradek.com/calc/battery-runtime.md?product=prod.prism-flex-mk-ii-encoder&wh=50).
- Prism Flex Mk II Encoder on a 98 Wh battery: about 4.9 h at typical draw (20 W), about 2.7 h at maximum draw (36 W). Workings: [/calc/battery-runtime.md?product=prod.prism-flex-mk-ii-encoder&wh=98](https://specs-dev.teradek.com/calc/battery-runtime.md?product=prod.prism-flex-mk-ii-encoder&wh=98).
- Prism Flex Mk II Encoder on a 150 Wh battery: about 7.5 h at typical draw (20 W), about 4.2 h at maximum draw (36 W). Workings: [/calc/battery-runtime.md?product=prod.prism-flex-mk-ii-encoder&wh=150](https://specs-dev.teradek.com/calc/battery-runtime.md?product=prod.prism-flex-mk-ii-encoder&wh=150).

Runtime = battery watt-hours ÷ stated draw: an estimate, not a measured runtime. Not included: the monitor, camera and accessories on the same battery, conversion losses, battery ageing and cold.
