All Remo-Tel smart devices contain an internal Lithium Ion backup battery that is contantly charging when power is supplied. When the power supply is disconnected, the fully charged backup battery will operate up to 48 hours. Remo-Tel smart temperature monitoring systems continue to record hourly readings during this period. Should temperature go out of your preset “safe range” during this time, an alert will immediately be sent to you. Once power is restored, the Remo-Tel system will immediately send a “Power Restored” alert and begin to re-charge the backup battery. Compost Remo-Tel smart devices are powered by an external rechargeable battery pack. When this battery dies, the internal backup takes over and will alert you of low battery. The internal backup re-charges upon replacement of the external battery pack.
