For S35i, BATT+ has a voltage level from +3.0V to 5.5V, and a BATT_TEMP contact is used for
detecting abnormal increase in temperature of the battery.
If the temperature is too high or too low, there is a high probability
that the battery is not charged. To enable the charging process again,
battery and phone needs to cools down or warm up. Battery

For the Lithium Ion battery, it is short-circuit protected by an electronics fuse. The fuse will be
activated in case a too high current is drawn. This fuse will
not reset
automatically.
The resetting of the battery fuse can be done with either of the following procedures:
1. Insert the battery into the S35i and then connect the rapid charger to the phone. Wait for
approximately 10 second, then the mobile can be turned on again.
