The Config App will tell you the daily energy consumption of any configuration that you set. The example below is for 24-hour continous recordings with 55 seconds individual WAV files and 5 seconds between them. Daily energy consumption is 280mAh and good quality rechargeable batteries will have a capacity of about 2800-2850mAh giving about 10 days. At sample rates of 48 kHz and lower, you can also select 'Enable energy saver mode' to save another 30% with a small decrease in recording quality. The final capacity depends a bit of temperature and the condition of the battery. The biggest variable in deployment lifetime in the choice of SD card as their energy consumption varies very widely - https://www.openacousticdevices.info/sd-card-guide - sometime by a factor of four. The energy calculations are for 32GB SanDisk Extreme (red and gold) cards which are reliable and low-energy. Larger cards will use a little more energy, but the difference between 64GB and 32GB is minimal.
