Dolphin QuadCharger
Overview
The Dolphin QuadCharger is a four-slot charging station that can charge a Li-ion battery in less than four hours. The fourth slot
features a battery analyzer that completely resets and re-calibrates a battery and displays its resulting capacity.
Compatibility
The QuadCharger is compatible with the Li-ion batteries that power Dolphin 7900 Series terminals.
Charging Process
Each charging slot works independently of the other three.
As battery packs charge, the charging circuitry follows the two-step charging process (CC-CV) that is recommended
for Li-Ion batteries. The process monitors changes in temperature, current, and voltage. The charger also resets
and calibrates battery pack data to accurately show battery status on the Dolphin display.
Use only the peripherals, power cables, and power adapters from Hand Held Products. Use of peripherals, cables, or
power adapters not sold/manufactured by Hand Held Products will void the warranty and may damage the terminal.
Use only the Li-ion battery packs provided by Hand Held Products. The use of any battery pack not sold/manufactured by
Hand Held Products in a Dolphin terminal will void your warranty and may result in damage to the Dolphin terminal or
battery.
Dolphin QuadCharger Parts and Functions
Front Panel
Charging Slots
The QuadCharger contains four charging slots. Each slot holds one battery. When a battery is placed in a slot, it
immediately begins charging.
Charge/Analyze Slot
This is the fourth slot and the only one that can be used to analyze a battery. When a battery is placed in this slot,
it begins charging just as it does in the other three slots. However, if you press the ANALYZE button, it runs the
battery in this slot through the complete Analyze cycle. For more information,
see Using the Battery Analyzer on
page 16-4.
