Example of Estimating Battery Life for One Year Deployment
21 Samples
Pre-deployment (system prep)
Controller Electronics (ON) – 3 hours
3 h x 9.0 mA
= 27 mAh
Deployment
Controller Electronics (Low Power Sleep) – 1
year
8760 h x 0.22 mA
= 1927 mAh
Bottle Rotation –
21 Cup
@26sec/rotation=546S = 9.1 min =
0.15167h x 380 mA
= 58 mAh
Recovery (offload data, remove samples)
Controller Electronics (ON) – 2 hours
2 h x 9.0 mA
= 18 mAh
Total Battery Consumption
= 2030 mAh

Bottle Rotation – 13 Cup
13 Cup @38sec/rotation=494S = 8.2
min = 0.137h x 380 mA
= 52 mAh
Recovery (offload data, remove samples)
Controller Electronics (ON) – 2 hours
2 h x 9.0 mA
= 18z mAh
Total Battery Consumption
= 2025 mAh
In these examples, the total energy consumed is less than the 5,000 mAh capacity of the battery
and the proposed deployment plans will have sufficient battery life.
