Dolphin QuadCharger
The Dolphin QuadCharger provides intelligent battery management for NiMH (Nickel Metal Hydride) Dolphin 7400/7450 battery
packs.
This device fully charges as many as four NiMH batteries in 2.5 hours. Charging slots work independently to control charging
and discharging of individual battery packs. The QuadCharger is compatible with all models in the Dolphin® 7400/7450 family of
hand held computers.
As battery packs charge, the charging circuitry follows a three-step process that senses changes in temperature and voltage and
drops to a trickle charge when the packs are fully charged. This feature allows the user to leave batteries in the charger
indefinitely, which maintains the batteries at peak capacity without damage. The charger also resets and calibrates battery pack
data to accurately show battery status on the Dolphin display.
The QuadCharger conditions and calibrates batteries for longer, more consistent performance.
