Question: Does the C401FS charger have the "recondition" feature like the C204F charger that I own.
Answer: The C401FS charger is so advanced that the internal charging circuit makes manual conditioning unnecessary. Since each battery is charged independently using the Flex Negative pulse charging algorithm, not only is each battery charged to its optimum capacity, but battery life is also enhanced. In fact, FLEX NEGATIVE pulse charging removes the crystal structure formed on battery electrodes (which is the source of "memory effect") and conditions your batteries as they are being charged. Full automatic charging on either Fast or Slow setting.
