    I can confirm that this is not what prolong instructions says and can potentially damage the battery.

    Yeah..., just sell the prolong and cash it to add funds for new battery

    You mean the bulb discharge wattage or which?

    Saw this video of a guy who used the Automated Prolong Charger and Discharger


    1st: Charge-Discharge 240+-~ to 134vdc.
    2nd: Charge-Discharge 240+~ to 101vdc
    3rd: Charge-Discharge 240+~ to 84vdc
    Then Charge

    UPDATE:
    My latest bulb arrangement for 220v bulbs:

    First Discharge:
    240+-~ to 196v: 400w or less bulb
    196v to 134v: 150w or less bulb

    Second Discharge:
    240+-~ to 196v: 400w or less bulb
    196v to 134v: 150w or less bulb
    134v to 101v: 50w or less bulb

    Third Discharge:
    240+-~ to 196v: 400w or less bulb
    196v to 134v: 150w or less bulb
    134v to 84v: 50w or less bulb

    But i use 60w in replacement for the 50w because i can't get a 50w bulb around.
    I have now attached the Prolong bulb charge voltage and wattage guide too.

    @Abarnabe Care to elaborate what's not right in @A.J's statement?

    Another question: do you need to turn on the traction battery fan during discharge, assume the light bulbs are located away from the battery and the surrounding is not extremely hot? I know you need the fan during charging to keep the battery from overheating.

    I have updated my post above with an updated wattage arrangement, it seem to revolve around the bulb wattage change arrangement.
