**MDR.S runs about 65.3 h at typical draw and 3.3 h at maximum draw on a 98 Wh battery.**

## Inputs

- product MDR.S
- battery 98 Wh

## Workings

- At typical draw: 98 Wh ÷ 1.5 W = 65.3 h.
- At maximum draw: 98 Wh ÷ 30 W = 3.3 h.

## Constants

- From Teradek product data, seen 2026-10-21: MDR.S typical power draw 1.5 W; MDR.S maximum power draw 30 W.

## Assumptions

- Runtime = battery watt-hours ÷ the product's 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.
