| Talkman A500 | 83
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.
