Charging an A500 or T5 Device
Figure 59: Talkman A500/T5 High-Performance Battery
The A500/T5 battery is a high-performance model. Unlike the T2 series batteries, which have contact points that are
flush with the case, the A500/T5 battery features a pin-out design.
CAUTION: A500/T5 series batteries and other Honeywell batteries are not interchangeable. If you try to
insert the wrong battery into a device, you may damage the device and the battery.
The A500 and T5 devices use a Honeywell Combination Charger that charges the high-performance battery while still
seated in a device or when removed from the device.
A500/T5 High-Performance Batteries Specifications
The A500 and T5-Series devices use a standard battery.
Standard Battery Weight 4.7 ounces (133.24g)
Electrical Specifications
• Cells: The high capacity battery pack uses two lithium ion cells.
• Voltage = 3.7V
• Watt Hours = 19WHr
• 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.
• The battery pack contains custom electronics that provide performance, temperature, and pack identification to the
device. This information is made available to voice management software.
• Battery Charging: The battery pack must be charged only 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:
Temperature: -40°C to 55°C (-40°F to 131°F)
Humidity: 95% non-condensing
