  • Battery Maximum Charging voltage...

    Hello,
    Which is the limit for pulse charging batteries in general?
    I always charged my small 7 Amp/hour gell batteries to max 16 volts, but now I'm rejuvenating a 70 Amp/Hour free maintenance car Battery (Varta 12 V L3 720 A (En)), and so far, it's bubbling at 15,11 volts... How much can I charge this one?
    For the record, I'm using a 7 filar Solid State using Patrick cap mode (actually, without the cap, only with a ultrafast diode from upper trigger to base of transistor), current draw from power supply is 1,32 Amp, and charging current is 0,84 Amp.

      Thank you, John, for your fast reply.
      This 15,3 volt limit it's for all kind of batteries, or only for the new ones?
      How about charging current, it's ok for this size of the battery?
