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.

place for charging and transport. Batteries may be carried in the

PowerCenter with negligible loss of battery power. Batteries may be

stored in the PowerCenter with power applied for charge maintenance.

The LCD displays in the PowerCenter show the charge remaining in

the batteries. The displays show additional information when the

system is doing diagnostic tests or calibrating the battery. The

PowerCenter has LED indicators for each battery slot to show when

the battery is being charged or discharged.

Power for charging batteries in the PowerCenter is obtained from an

Apple AC or Lind DC power adapter. A power cable is supplied to

connect the PowerCenter to the PowerBook. See Appendix I and II for

a description of Intelligent Battery operation.

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.
