    Hello

    I am trying to work out how long it would take to charge a lead acid GEL battery at a given power

    The input power is 100W
    V = 17V
    I = 5.89A

    The battery i am trying to charge is a 12V battery.
    Model: BEG120120

    As mentioned earlier, I am trying how to work out the time on how long it would take to charge the battery.

    Thank you in advance

    As I mentioned in your last thread #4, When you first time charge the battery, you better using 0.1C or less to charge the battery, C is the current of battery.
    5.89A*0.1 = 0.589A
    5.89A/0.589A=10 hrs

    The normally charging time is 0.3C.
    5.89A*0.3 = 1.767A, it means that the Imax for charge current.
    5.89A/1.767A=3.333 hrs
