Agilent AN 372-2
Battery Testing
Application Note
An electronic load can be used to discharge batteries of various
chemistries to determine actual capacity, capacity retention,
and internal impedance.
"Loading the manual" means you need to wait until the file loads and becomes available for online reading. Some manuals are very large, and the time they take to appear depends on your internet speed.
Summary
2 Increasing demand for portable DCpower has risen from improvementsin battery and motor design technol-ogy. More than ever before, portableDC powered products have becomeavailable in many diverse applications.Rechargeable batteries appear in alltypes of products from analyticalelectronic equipment ...
3 Seven standard test procedures 1 are used to verify certain electrical char-acteristics of secondary batteries: 1. Rated capacity2. Capacity retention3. Effective internal resistance4. Discharge rate effect on capacity at –20°C 5. Discharge rate effect on capacity at 23°C 6. Life cycle performance...
4 Capacity varies with the rate of dis-charge as shown in Figure 3. Testingfor how discharge rate affects capacityis discussed later in more detail.Generally, lower discharge rates overlonger periods of time yield highervalues of total capacity. It is impor-tant to realize that since dischargerate a...
