    See answer

    Reconditioning is activated by pressing the Mode button and selecting "Recond". When the charger is in "Care" mode it also means that the reconditioning is complete.

  • CT5 POWERSPORT: Is POWERSPORT a simpler charger than the MXS 5.0? It has only three lights while the MXS 5.0 has eight.
    See answer

    No. Both chargers contain an eight-stage charging programme, but they show this differently. On the MXS 5.0 a light shows for every step, and the voltage and power curve is shown above and below the lights. On the POWERSPORT we've chosen to reduce the number of lights and instead just show which phase the charger is currently in – Check, Charge or Care. However, MXS 5.0 is a more powerful charger than POWERSPORT.
