Battery Connector

The electrical specifications for the battery connector is shown in
NO TAG. The BSI contact on the battery connector is used to detect when
the battery is to be removed to be able to shut down the operations of the
SIM card before the power is lost if the battery is removed with power on.
The BSI contact in the battery pack is 0.7mm shorter than the supply
power contacts to give enough time for the SIM shut down.
