This feature\u00a0makes testing and characterizing of battery packs extremely easy to perform. This<br \/>\napplication note will describe the sequence of steps necessary to determine the\u00a0Amp\/Hour rating of a battery pack.<\/p>\n<p>The CSI3721A <a title=\"programmable DC electronic load\" href=\"https:\/\/www.circuitspecialists.com\/programmable-dc-electronic-loads\">Programmable DC Electronic Load<\/a>\u00a0is ideally suited for testing any battery but especially rechargeable\u00a0battery packs such as Li-Ion because the discharge termination voltage can be\u00a0set to avoid discharge below the safe voltage limit. This allows unsupervised<br \/>\ndischarge of the battery pack under test.<\/p>\n<p>1.) Power ON the CSI3721A and Press the INPUT ON\/OFF button to disable the\u00a0Load and then connect the battery pack observing polarity.<br \/>\n2.) Press and Release the 2nd button then Press the 6 (Battery) button to enter\u00a0the battery discharge mode of operation.<br \/>\n3.) Press the SET button and enter the desired discharge parameters using\u00a0the \u2191 and \u2193 buttons to select the parameter, and the \u2190 and \u2192 buttons\u00a0together with the rotary knob or numeric keypad to enter desired values\u00a0for termination voltage and discharge current.<br \/>\n4.) Press the CLEAR button to exit the parameter entry screen.<br \/>\n5.) Press the INPUT ON\/OFF button to begin the automatic battery discharge\u00a0test.<br \/>\n6.) The CSI3721A will proceed to discharge the battery at the discharge current\u00a0value set in step 3 and will automatically stop the discharge test of the\u00a0battery when the battery voltage equals the value set. At this time the\u00a0elapsed time that was required to discharge the battery and the Amp\/Hr\u00a0rating of the battery may be viewed on the LCD screen.<br \/>\n7.) To exit the battery discharge mode of operation, press and release the 2nd\u00a0button then press the 6 (Battery) button.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>The Circuit Specialists
