Charging a T2-Series Device
The T2 series battery is available in standard and high-capacity models. The standard battery sits flush with the top of
the device when installed. The high-capacity battery has a longer run time than the standard capacity battery.
CAUTION: T2 series and A500/T5 series batteries are not interchangeable. If you try to insert the wrong
battery into a device, you may damage the device and the battery.
The T2-Series battery is designed to be charged while still seated in the device.

Electrical Specifications
•
Cells: The high capacity battery pack uses four lithium ion cells.
•
Nominal voltage = 7.2V
•
Watt Hours = 27WHr (standard T2x battery is 14WHr )
•
Protection circuit characteristics: The pack contains a protection circuit that prevents over and under voltage
conditions on the cells and protects the pack from damage as a result of a short circuit between the positive and
negative terminals of the battery.
•
Thermistor: The battery pack contains a negative temperature coefficient thermistor. The charger uses the voltage
drop across the thermistor to determine that the battery pack is within the proper charging temperature limits.
•
Battery ID: The battery pack contains a Dallas Semiconductor DS2401 serial ID chip. In future enhancements to
both the device and the device software, this chip will be used to provide data about features such as battery life,
capacity monitoring and asset tracking.
•
Battery Charging: The battery pack must only be charged in a Honeywell designated charger.
Mechanical and Environmental Specifications
•
Drop-test specifications: The high capacity battery meets the MIL STD 810F specification for shock and transient
drop criteria.
•
Environmental specifications: The battery pack halves are sonically welded together to protect the internals from
water and dust.
•
The battery functions properly in the following conditions:
