Large Battery Pack Option: The Large Battery Pack provides continuous use for up to 2.5 years. The battery will allow you to measure and record over long periods of time whether the unit is in transit or in a distant place.
Note: Battery life will depend on the recording environment, recording interval, communication frequensy, and ambient temperature. The above battery life test was carried out using brand new batteries and in no way do we guarantee a battery's life. Removing the battery and not replacing it will result in a loss of all recorded data.
