BATTERY INFORMATION
Replacement
We recommend that you replace the baery prior to logging crical data. Only use 3.6V ½AA lithium metal baeries. The data
logger does not lose its stored readings when the baery is discharged or replaced; however, the data logging process will stop and
will not resume unl the baery is replaced and the logger restarted by EL-WIN-USB.
Before replacing the baery, 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 baery capacity to be lost.
Passivaon
If le unused for extended periods of me, lithium metal including those baeries used in the EasyLog range of data loggers
naturally form a non-conducve internal layer, prevenng them from self-discharge and eecvely increasing their shelf life. When
rst installed in the data logger, this may cause a momentary drop in the baery voltage (the Transient Minimum Voltage) as
the internal layer is broken down, resulng in the data logger reseng. Inserng the baeries in the data logger and leaving it
connected to a PC for about 30 seconds will remove this layer. Aer this, remove and re-install the baeries to reset the data
logger. Overall baery life will not be aected.
WARNING
Handle lithium metal baeries carefully, observe warnings on baery casing. Dispose of in accordance with local regulaons.
