Thank you for purchasing the Lind PowerCenter 500 battery service
system. PowerBook Intelligent Batteries represent a technical break-
through in portable power management. Products that support this
battery system require a similarly high level of technical effort.
In the development of the PowerCenter and it's companion software,
we created the most full featured battery service product on the market.
Functions include error analysis and correction as well as charging,
conditioning and calibration. In the course of this development, we
found it necessary to analyze in detail all Intelligent Battery operations.
Most of the results of our battery analysis are contained in the
PowerCenter manual. We did not intend to write such an extensive
manual but a good understanding of the Intelligent Battery is essential
to understanding the operation of the PowerCenter and the Intelligent
Battery Utilities System (IBUS™) software.
We welcome your comments about our products. Please take time to
write or call us with your suggestions. Your satisfaction is our goal.

Lind Battery Utilities™ 500
The Lind Battery Utilities 500 software program, is designed to analyze
stored battery parameters and allow the user to correct data that is out
of the normal range. Batteries that do not perform properly in the
PowerBook or the PowerCenter should be examined with this program
to determine if stored data corrections are necessary.
Power Sources
Power to operate the PowerCenter is obtained from an Apple AC
adapter or Lind DC Adapter™ 500 (12 volt Automobile Power Adapter
Model PB-5). A power cable, supplied with the PowerCenter, is used
to connect the PowerCenter to the PowerBook when:
- The PowerBook and PowerCenter are using power from the same
adapter.
- The PowerCenter is used as an Auxiliary Power Source.
- The PowerBook is used as a load for calibrating and conditioning
batteries.
Note: AC and DC adapters that do not have the capability to operate
and charge the PowerBook at the same time will not operate properly
with the PowerCenter 500.

BATTERY CHARGING
One or two PowerBook 500 series Intelligent Batteries can be charged
in the PowerCenter. The batteries are charged in sequence with the
first battery inserted being charged first. Diagnostic tests are per-
formed on batteries when inserted into the PowerCenter to assure all
battery and microprocessor functions are correct for proper charging
or use of the battery. Power for charging batteries is obtained from
the Apple AC adapter (supplied with the PowerBook) or a Lind DC
Adapter 500.
Battery Charge Procedure
• Apply power to the PowerCenter from one of the recommended
power sources.
• Insert one or two Intelligent Batteries into the PowerCenter.
-Diagnostic tests are run on each battery when it is inserted.
-Tests on a normal battery are completed in less than ten seconds.
- The LCD display indicates the percent of charge in the battery.
- The PowerCenter will not charge a battery with over 98% charge
remaining.
• The PowerCenter begins charging the first battery inserted.
• The ‘Charge’ LED comes ON to indicate the battery is charging.
- The battery charges at the same rate as in the PowerBook.
- A fully discharged battery charges in 1.5 to 2 hours.
- The charge in the battery indicated on the LCD display will
increase as charging progresses.
• At full charge, the ‘Charge ‘ LED turns OFF and the LCD display will
read 100% (see Note 1).
• The PowerCenter automatically begins charging the second battery
inserted.
• The charge cycle proceeds as described above to complete second
battery charging.
• Pulse maintenance charging maintains both batteries at full charge.
Note 1 - If the LCD display jumps to100% at the end of charge or
remains at 100% for a long period before charging is completed, this is
an indication that the battery needs calibration. The battery displays the
amount of charge it believes it contains but the display resets to 100%
when it has reached full charge. This display reset should not be
confused with calibration.
Note 2 - When the PowerCenter is connected to a PowerBook, battery
charging in the PowerCenter is delayed until the PowerBook's internal
batteries are fully charged or removed. The PowerCenter's 'Charge
LED' will blink while charging is delayed.

AUXILIARY POWER SOURCE
One or two Intelligent Batteries inserted into the PowerCenter may be
used as an external Auxiliary Power Source for the PowerBook. These
batteries supply power to the PowerBook sequentially until they are
depleted. The PowerBook then continues to operate from internal
batteries. Using the PowerCenter as an auxiliary power source has the
following advantages:
• No need to interrupt PowerBook operation to swap batteries.
• Two or three times the operating time obtained with 1 or 2 internal
batteries.
• Frees the second battery slot for accessory modules without
sacrificing run-time.
• The charge remaining in the external batteries is conveniently and
continuously shown on the LCD displays of the PowerCenter.
Batteries recharged in the PowerCenter may be removed and inserted
into the PowerBook for maximum operating time.
Auxiliary Power Operation
• Connect the power cable from the PowerCenter output to the
PowerBook.
• Insert one or two Intelligent Batteries into the PowerCenter.
- A single battery may be placed in either side of the PowerCenter.
• Press the ‘Mode Switch’ on the PowerCenter until a ‘RUN’ LED
comes ON.
- The PowerCenter will now supply power to the PowerBook.
• The charge remaining in each battery is displayed continuously on
the LCD screens of the PowerCenter.
• The PowerCenter automatically switches to the second battery
when the first battery is depleted.
- The ‘Run’ LED of the second battery will come ON.
- A battery may be removed from the PowerCenter during
Auxiliary Power use without interrupting operation of the
PowerCenter or the PowerBook.
- The PowerCenter automatically shuts down when the second
battery is fully depleted. The computer then switches to internal
batteries.
Note- If the computer goes to sleep or is turned OFF, the PowerCenter
will automatically turn OFF in 3 minutes. The PowerCenter ‘Mode
Switch’ must be pressed to re-establish Auxiliary Power operation.
Note - It is recommended that the PowerBook have an internal battery
in place when any external power source is in use. This practice will
avoid loss of data if the external power cable is inadvertently discon-
nected.
