(This refers to a specific battery issue some users have experienced in winter without room heating system.)
The CR2025 battery used by the iFertracker cannot cope with low temperatures. The combination of low room temperature and the iFertracker’s auto on/off function causes the battery to be drained very quickly.
If your room temperature is below 20℃/68℉, keep the battery in a warm place (above 20℃/68℉) for at least an hour or hold the battery in your hand for 5-10 minutes before using, and sync data immediately after taking the device off in the morning. If the battery is already in the device, hold the iFertracker in your hand for 15-30 minutes before syncing data.
