Battery Pack and Charger - Part No. 35753
(for TTR100's produced AFTER 06/2012)
The 35753 Rev 6 battery pack is designed with a temperature sensor switch to
protect the battery pack from overheating. If the temperature of the battery pack
rises above 60 degrees C during the charge cycle, the switch will disconnect the
battery pack from the charger.
Example conditions that could trigger this switch are:
 Elevated ambient temperatures (>35 deg. C) - or -
 If the battery is connected to the charger with ≥20% charge remaining - or -
 When the ambient temperature is elevated and the instrument has not
indicated it is time to charge the battery pack.
The charger operation will change if subjected to the following types of
conditions:
 If the battery pack is charged before the instrument indicates it is time to charge
the battery, the battery pack temperature may rise above the 60 degrees C trip
point. In that event the battery will be disconnected from the charger and the
charge LED will extinguish.
 After the battery pack temperature lowers, the switch will again connect the
battery pack to the charger and allow the charging to continue.
 The charge LED will once again light.
 This however resets the built-in 3 hour charge timer.
 This sequence may continue several times.
 It is safe to charge the battery overnight. The next day the charge indicator
LED may not indicate that the charge is complete but the charge will likely be
≥90%.
 You may check the battery charge by turning on the instrument and observing
the battery capacity.
