    12291229 * The BR1225 coin cell is rated at 50mA/hours. Battery lifetime can be calculated by taking the battery rating divided by the current drain. The GSC's typical drain depends on the version:
    12301230  - v1/v2 (!Laguna/Ventana): ~1.5uA: (50mA/hour)/(1.5uA) = 33.33K hours = 1388 days = 3.8 years
    1231   - v3 (Newport): ~1.2uA: (50mA/hour)/(1.1uA) = 45.45K hours = 1893 days = 5 years
     1231  - v3 (Newport): ~1.0uA: (50mA/hour)/(1.0uA) = 50K hours = 2083.3 days = 5.7 years
