BATTERY INFORMATION
Replacement
We recommend that you replace the baery prior to logging crical data. Only use 3.6V ½AA lithium metal baeries. The data
logger does not lose its stored readings when the baery is discharged or replaced; however, the data logging process will stop and
will not resume unl the baery is replaced and the logger restarted by EL-WIN-USB.
Before replacing the baery, remove the data logger from the PC. Please note that leaving the data logger plugged into the USB
port for extended periods will cause some of the baery capacity to be lost.
Passivaon
If le unused for extended periods of me, lithium metal including those baeries used in the EasyLog range of data loggers
naturally form a non-conducve internal layer, prevenng them from self-discharge and eecvely increasing their shelf life. When
rst installed in the data logger, this may cause a momentary drop in the baery voltage (the Transient Minimum Voltage) as
the internal layer is broken down, resulng in the data logger reseng. Inserng the baeries in the data logger and leaving it
connected to a PC for about 30 seconds will remove this layer. Aer this, remove and re-install the baeries to reset the data
logger. Overall baery life will not be aected.
WARNING
Handle lithium metal baeries carefully, observe warnings on baery casing. Dispose of in accordance with local regulaons.
