• Note: The drop test failure criteria consists of the following:
1. A split or separation of the ultrasonic weld joint greater than one linear inch.
2. Inability to meet open circuit voltage, serial number input, thermistor output,
and charge tests.
Minor cosmetic damage to the battery, such as scratches and dents, is acceptable.
• 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:
Temperature: -4°F to 122°F
Humidity: 95% non-condensing
Rain/dust: IP67

High Capacity Battery Specifications
Electrical Specifications
• Cells: The high capacity battery pack uses four lithium ion cells.
• Nominal voltage = 7.2V
• Capacity = 3000mAhr or greater
• 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 terminal and the terminal software, this chip will be
used to provide data about features such as battery life, capacity monitoring, and asset
tracking.
• Battery Charging: It is very important to note that the battery pack should only be
charged in a Vocollect designated charger.
Mechanical and Environmental Specifications
