| Time Accuracy |
±1 minute per month at 25°C (77°F) |
| Battery Type |
Two AAA 1.5 V alkaline batteries, user replaceable |
| Battery Life |
1 year, typical with logging interval of 1 minute and Bluetooth Always On enabled; 2 years, typical with logging interval of 1 minute and Bluetooth Always On disabled; and temperatures between 0° and 50°C (32° and 77°F). Faster logging intervals and statistics sampling intervals, burst logging, remaining connected with the app, excessive downloads, and paging may impact battery life. |
