As with all the LOGiT loggers, you have a choice between using an Alkaline or a Lithium 9V battery. The loggers can operate twice as long Lithium battery than on an Alkaline battery. For the LT2 logger selecting the right battery has another important consideration. The internal temperature sensor is rated for temperatures between -40°F to 150°F (-40°C to 65°C). However, this range can only be achieved when using a Lithium battery. If you are using an Alkaline battery, the internal sensor temperature range is reduced to 32°F to 140°F (0°C to 60°C). This is because the Alkaline battery is not rated outside of this temperature range.
The temperature ranges are summarized in the table below.
