Replacing the Battery
Follow these steps to replace the battery:
1. Open the U30 enclosure and disconnect the external power source (AC adapter
or solar panel) first, then the battery, and finally any Smart Sensors. For U30/GSM
and U30/Wi-Fi models, use a 5/16" wrench to unscrew the antenna connection.
For the U30/Ethernet model, disconnect the Ethernet cable.
2. Use a Phillips-head screwdriver to remove the four screws at the corners of the
logger (clear inner case), and then remove the logger.
3. Use a Phillips-head screwdriver to remove the bar that secures the battery.
4. Remove the battery. Remove the cable from the old battery.
5. Remove the protective caps from the terminals of the replacement battery.
