ELECTRICAL CHARACTERISTICS (continued)

correlation using statistical quality control (SQC) methods.

Note 3: Contact factory for alternative values.

Note 5: Guaranteed by design, not production tested.

Note 6: When the charger is in its DONE state, it restarts when the battery voltage falls to the charger restart threshold. The battery

= 4.2V - 100mV = 4.1V.
