1. abacus4u & AbacusIEEE Sample calculation

2. Select Battery Type(s)
Select Electrode Type, Lifetime, Outlet type,
and Application
Select Manufacturer(s) and Batterie Type(s)
For NiCd, select special settings, i.e. Charging Efficiency and Voltage Depression

3. Select System Voltages (IEEE mode)
Use Float voltage or Boost voltage
or a combination of both for charging
Decide how to calculate applicable numbers of cells from given voltages
IEEE mode calculates max number of cells from maximum system voltage and final voltage per cell from minimum system voltage

4. Insert Load Profile Average voltage and nominal voltage
can be set if known
Five different load types and calculation modes to choose from
Average voltage
may be set individually for every duty cycle step
Power load configurable via apparent load input
Fully editable load profile
IEEE Random Load selectable

5. Provide additional data
Temperature settings
Additional settings for fine-tuning the input
Customizing of calculation range

6. All matching results in list
Normed IEEE Worksheet or special Abacus Report
Overview result list fully sortable, groupable and exportable

7. IEEE calculation worksheet
