Interchangeable battery-packs and housings:
NiMH rechargeable (left, p. 21), alkaline (center, p. 23) and lithium (right, p. 25).
The logger automatically detects the type of battery in use, which prevents
damage to non-rechargeable batteries if the charger is connected by mistake.
To remove the battery housing from the logger (in order to replace with a
new one or to change the battery type in use), see p. 23.
For disposal of batteries, see p. 34.
When the communications lead is attached, the logger is powered via USB.
Batteries can be left in the logger, but they are not then required (except when the
logger is being reset for a non-telemetry run; see p. 41).
