The AudioMoth configuration app uses the given recording settings and periods to calculate the approximate energy consumption of the device each day in mAh. On average, good quality alkaline AA batteries have a capacity of approximately 2600 mAh, whereas equivalent lithium batteries have approximately 3600 mAh.
Due to the low power consumption of the AudioMoth in general, any AA battery is suitable for standard deployments. For more intensive deployments involving long recordings or high sample rates, we advise using lithium batteries to maximise lifetime. AudioMoth battery cells are arranged in series.
