If a CR200X-series datalogger has not been used in a while and the internal battery is low, will the battery recharge if the datalogger is connected to a power supply? Or does the battery need to be replaced?

The internal battery is not rechargeable. In the case of low internal battery voltage, data will only be maintained as long as a power supply is connected. Collect all data from the datalogger before disconnecting the power.

The battery, a 15598, is not user replaceable. The datalogger should be returned to Campbell Scientific to have the battery replaced. To request a returned material authorization (RMA) number, follow the steps listed on our Repair and Calibration page.
