Description

This is a fast battery charger for Dell™ model D820, D830 & D831
batteries only. Do not attempt to use this charger with any other battery
type. Eight battery charging pockets are provided to rapidly service this
specific battery series. Working from a common line power outlet, a

maximum 600 Watt power supply mounted internally provides all the
necessary power for charging these batteries as described below.

Preparation for Use

Place the charger unit on a sturdy horizontal surface with its line cord
exiting the unit from the back side (the side away from the user). The
power switch will be on the side nearest the user. Plug the AC line cord
into a standard 115 VAC socket. The cord serves as the disconnect
device. The line outlet socket must be near the unit and easily
accessible. The circuit should be qualified to handle at least 15 Amps
and be relatively free of other heavy loads while the charger is operating.

Operation and User Interface

Press the rocker switch in to turn the charger power supply on. If line
power is present, the power indicator will illuminate steady green and the
power supply fan will become active producing an audible sound (this is
normal). Place batteries into charger pockets in any position or sequence
being careful to orient the batteries so the connectors line up, then gently
pressing them down all the way into the pockets. Each of 4 pairs
(front/rear) of pockets operates independently charging batteries
sequentially based on which battery was inserted first. When a battery is
seated properly in a pocket its corresponding LED will illuminate solid
yellow if the battery is the first of the pair to be inserted, or will blink yellow
if the battery is the second of the pair to be inserted. When a pocket has
finished charging, its LED will turn solid green and the second pocket of
that pair will begin charging, if necessary. If a fully charged battery is

inserted, the pocket will indicate charging for a short time, then terminate
with the indicator showing solid green. See below for a complete list of
status indicators. Batteries may remain in the pockets indefinately or be
removed at any time without damage. It normally takes 4 to 6 hours to fully
charge a battery.

Smart Battery Calibration

Dell™ series batteries mentioned above are 'smart'. They have an internal
controller that interacts with the charger to report charge status and other
information. Through normal use errors in the estimated charge level will
accumulate and cause false readings. These errors can be eliminated by
recalibrating the battery's internal controller. This charger has the facility to
calibrate batteries placed in the left-most front pocket. To trigger calibration of
a battery in this pocket, momentarily press the front-panel calibrate switch.
The start of a calibration cycle will be confirmed by a blinking yellow/green
indicator. The calibration cycle may take up to 9 hours. When finished the
battery will be fully charged and the controller will be calibrated to that state.

Charger Status Indicators

A tri-color LED indicator is located below each pocket to indicate
charge status of the battery in that pocket:
