Why is it that when I try charging my fully discharged NiCd battery at the C rate, the CASP charges OK for a few minutes, then terminates, indicating that the battery is charged?
Several things could be happening. The battery could be defective, the battery parameter tables may have an erroneous entry, the wrong cable may be connected to the CASP, or some other “Cockpit” error may be occurring. All of these items should be checked and determined to be correct. If no “Cockpit” errors are found, then try charging the battery at a C/2 rate. If you are able to charge the battery for a longer time period before termination occurs, you have probably been trying to charge the battery too rapidly. For optimal charging you need to determine the value of “n” in the C/n equation. For the CASP/1500, /2000 and /2500 you can do this empirically by trial and error, by plotting the charge curves, by reviewing the battery specifications, and/or by contacting the battery manufacturer. For CASP/1000, /1100 and /1200, you will be unable to modify the pre-programmed battery tables without the TD-639 or TD-700 software unless you have a CASP/1500 or CASP/2000 from which to download.
