> What is the switch on the battery for? It came switched on ...
It's a storage switch that disconnects the cells from the
microcontroller in the battery, so it doesn't discharge them below
their recommended minimum voltage. If you flip it, you'll need to
recalibrate the battery. It should be on for normal use, off for
long-term storage of the battery.
