Page 4: Lpc-500 Overview
LPC-500 OVERVIEW The Lind PowerCenter™ 500 is a multi-function battery service unit designed to: • Charge Batteries. • Condition and Calibrate Batteries. • Serve as an Auxiliary Power Source. • Perform Intelligent Battery Management Tasks. Specific capabilities are: • Charges one or two 500 series Intelligent Batteries outside the PowerBook. -
Page 5: Fast Start Operating Instructions
Fast Start Instructions Battery Charging Apply power to the PowerCenter. Insert one or two Intelligent Batteries. If the battery passes automatic diagnostic tests, the 'Charge LED' comes ON and the PowerCenter begins charging. At full charge, the LCD display will read 100%. The Charge Cycle repeats to charge the second battery. -
Page 6: User Information
- 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. Page 6... -

Page 9: Battery Charging
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. -
Page 10: Auxiliary Power Source
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. -
Page 11: Conditioning And Calibration
CONDITIONING AND CALIBRATION Relationship of Conditioning and Calibration Battery conditioning and calibration are two separate operations that are necessary for different reasons. Both require the battery to be charged, then discharged to a level below the PowerBook's normal shut off point. When a battery is calibrated it is also automatically conditioned. -
Page 12: Battery Calibration In The Powerbook
Battery Calibration In the PowerBook The PowerBook performs battery calibration under a specific set of circumstances. Calibration of a battery will occur if: • Two batteries are installed in the PowerBook. • One or both batteries are allowed to completely charge •... -
Page 13: Condition And Calibration Procedure
CONDITION AND CALIBRATION PROCEDURE Set Up This procedure may require up to 5 hours if a battery is completely discharged at the start of the operation. Two batteries are completed in less than 7 hours. • Connect a proper power adapter to the PowerCenter. •... -
Page 14: Calibration Procedure
Calibration Procedure • Insert one or two Intelligent Batteries into the PowerCenter. - The normal diagnostic tests are run and the LCD displays the percent of charge in the battery. • Momentarily press the “Mode Switch” to put the PowerCenter into the battery calibration mode. - Page 15 NOTE 1 - The PowerCenter charges one battery while it discharges the other to reduce the calibration time of two batteries. NOTE 2 - An interruption in input power will cancel the calibration sequence for batteries that have not already completed the sequence. The PowerCenter will default into charging mode and the batteries will be charged when power is restored.

Page 16: Diagnostic Tests
DIAGNOSTIC TESTS and ERROR MESSAGES A number of communication and battery data examination tests are run when an Intelligent Battery is inserted into the PowerBook computer. Similar tests are run by the PowerCenter to assure the battery is in proper condition to proceed with a charge or use cycle. The tests can require as little as 3 seconds for a good battery and as long as 15 minutes for a battery that has over discharge and /or shorted cell problems. -
Page 17: Error Codes
ERROR CODES Fatal Error Codes Error codes E1 or E2 indicate a battery has serious problems. Prob- lems could include: - Cells have been damaged by severe or prolonged over discharge. - One or more cells are shorted - Internal Battery protective devices have been activated - Intelligent Battery circuit failures have occurred. -
Page 18: Over Discharged Battery Recovery
OVER DISCHARGED BATTERY RECOVERY Description Of Recovery If an Intelligent Battery has discharged to a very low level, the internal microprocessor of the battery will not operate and there will be no communication with the PowerBook or the PowerCenter. If communi- cation is not established when a battery is inserted, the PowerCenter first attempts to reset the battery microprocessor. -
Page 19: Shorted Cell Tests
SHORTED CELL TESTS Description Of Tests The diagnostic test sequence includes a shorted cell test that may run as long as 12 minutes. During this test, charging power is applied in a series of pulses with voltage stabilization and test periods between pulse applications. -
Page 20: Limited Warranty
We urge you to fill in and send us the warranty card for the PowerCenter 500. This will provide us with your address so we can notify you of upgrades in hardware or the software that may be used in conjunction with the PowerCenter. -
Page 21: How The Intelligent Battery Works
APPENDIX I HOW THE INTELLIGENT BATTERY WORKS The Intelligent Battery for the PowerBook 500 series of laptop comput- ers contains a microprocessor controlled data gathering system that monitors battery status and level of charge. This data is communicated to the Power Management system of the PowerBook where it is used to generate the capacity and time remaining displays as well as to control charge and discharge of the battery. -
Page 22: Charging And Discharging
Charging and Discharging When the battery is charged, the battery communicates the increase in % of charge as current flows into the battery. The battery stops charg- ing when the internal temperature rises to a preset level indicating it can not take any more charge. The % of charge reading should be about 100% when charging is complete. -
Page 23: Appendix Ii Battery Calibration
APPENDIX II BATTERY CALIBRATION What is calibration? Calibration is the process of updating the ‘100% capacity number’, stored in the battery, to a new and more accurate value. How is the battery calibrated? The battery is calibrated by: • Charging the battery to full capacity. •... -
Page 24: Memory Effect And Conditioning
APPENDIX III MEMORY EFFECT and CONDITIONING Nickel Cadmium (NiCd) and Nickel Metal Hydride (NiMH) batteries may lose part of their operating capacity over time. This loss usually occurs when the battery is on trickle charge for long periods or the battery is seldom fully discharged. -
Page 25: Appendix Iv Battery Storage And Use
APPENDIX IV BATTERY STORAGE AND USE A battery will lose a portion of it’s charge when not in use. Some of these losses can be reduced and some can not. The chart on page 26 shows the effect of the losses on the charge retained by the battery. A. - Page 26 Due to the charge loss factors listed, it is recommended that 500 series Intelligent Batteries be recharged about every two weeks to assure that partially charged batteries do not discharge below the microprocessor operating level. The PowerCenter will perform the Over Discharge Recovery operation when necessary but frequent over discharge may shorten the service life of a battery.
