If a CR200X-series datalogger has not been used in a while and the internal battery is low, will the battery recharge if the data logger 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 data logger before disconnecting the power.

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