Experience shows that the NiMHi batteries benefit from periodic cycling. There are two main circumstances where cycling the battery pack may improve performance.
-
- * The new battery has completely discharged during a period of storage. The battery will discharge completely in approximately two months. The longer the batteries have been stored, the more cycling will be required to restore the full capacity. After two years in storage, it may never be possible to restore full capacity.
- * If external power is used for long periods of time, an overcharge condition may exist. This will cause the capacity of the battery to be reduced.
- * The new battery has completely discharged during a period of storage. The battery will discharge completely in approximately two months. The longer the batteries have been stored, the more cycling will be required to restore the full capacity. After two years in storage, it may never be possible to restore full capacity.
Procedure For Cycling The battery
1. Charge the battery until all green LED's are on and the red LED has gone out.
2. Remove external power supply. Run Digital Multimeter program until LDS3000 switches off.
NOTE: The Digital Multimeter program suspends the Windows 95 power management, and requires the most power from the battery.
3. If LDS remains powered for greater than 30 minutes, the pack is conditioned. If the pack is not conditioned, repeat Steps 1 & 2.
NOTE: The discharge time should be longer this time. If battery capacity is not increased by cycling, the battery pack is probably faulty.
4. Cycle the battery once per week.
NOTE: The battery discharge time will reduce as the battery ages.
When being charged, the LED will flash until the minimum acceptable voltage is reached. If the LED continues to flash after 20 minutes, the pack has a shorted cell. This causes the voltage to only reach 6 volts.
NOTE: Equally, though extremely rare, the LDS may not be able to provide the required charge voltage, giving the same effect. Trying another battery pack will be the only conclusive answer.
If the LDS is not connected to an external power source and the orange LED starts to flash, this is an indication of the pack providing too much current causing the cells to overheat.
Battery Life For A Portable Unit
NOTE: The typical battery life applies to fully charged new batteries.
The battery life will vary from 30 to 75 minutes depending on operating variables.
The charge time is three hours.
NOTE: The charging time is from full discharge to full charge.
