    …but what about if you're running the A/C? I did this test yesterday, and found it to show around 55-60 (several times) when the A/C was turned "off" and about 48-ish with the A/C running. :) (BTW I just started the mid-year "Full-Monty" about 2 hours ago!)

    Well, it's that time of the year, so here we go again:
    1st Charge:
    20190611 14:15 224V 360mA
    20190611 21:38 237V 360mA
    (…to be continued)

    I had originally planned on my full session this week too but Mother Nature has interfered. 100*+F here a couple of days this week already. If the extended forecast doesn't cool off some before the end of the month I'll only be able to do a "charge and balance only" session during the night before we go on our cross country trip.

    Mine gets 55 with the air on. For how long I don't know but so far so good.

    Maybe I am misreading, but the discharge to 84V started at 14:45 and the "data point" occurred at 19:13. Should that be ~4 1/2 hours instead of 5 1/2?

    Is the significance of the data point (at 134V) to compare it to the first discharge down to 134V...which took 6 hours (assuming the 16:30 end time was exactly when the discharger finished)? Comparing 6 hour discharge1 to 4 1/2 hour discharge2? Does the discharger perform identically down to 134V when set to different termination voltages (134 and 84)?

    Please forgive my ignorance. I'm very new to battery reconditioning. I performed my first recently and am trying to make sense of the data. Understanding the process and equipment is a huge help. Thank you, in advance!

    Ah! My bad! (…ooops! :oops:) you are correct!

    The readings I posted are (and were) for reference points only, with a view to giving me (and anyone else) a better plan the next time! If you take the time to look at all my previous postings (no, I don't have the time either) you will find that for several of my earlier FullMontys, I miscalculated the anticipated discharge time to get to 134V, but that each subsequent time I got closer!…

    …and to your last point - I think you are correct and that the discharge path is similar no matter what the target is! (…based on my observations so far! (…I think this to be my 11th or 12th FullMonty) (…shouts of "…and he still can't get the bloody thing right!")

    ;)

    …ah, I think I see what you're getting at…

    16:30 done, plus bounce back to 192V

    …the bounce-back happens after the target is reached, and is a normal occurrence. According to Hybrid Automotive's @jeff652 that behaviour is perfectly normal, and is nothing to worry about. The extra time in there was the time it took to get up to 192, and then back down to 134V. I'm sure that eventually Hybrid Automotive might even add some smart features to their "Intelligent" Discharger which sends a signal to your SmartPhone (c,mon, guys , this is the 21st Century!) allowing you to control the device, or at least display the current voltage/current?) @jeff652 ?

    The discharger I have is an early Mark1 model, (I also have the Mark0 (Lightbulb) version, but mine has the fiddly little knob to select the discharge voltage which can hardly be accurate having such a small scale! At least the later models have preselected voltages (or so I understand)!

    15:10 238V 360mA
    17:15 241V 360mA. (about 21 hours)

    Discharge to 17V:
    17:15 239V 2.28A
    21:20 162V 0.22A
    22:32 17V 0.22A. (5h 17m)

    Final Charge:
    22:37 186V 360mA flickering current (normal)

    …should be finished later today

    This is correct. The bounce back happens because when you remove the load, the cells will try to revert to their nominal voltage. Of course if you were to re-apply a load, they would immediately drop back down.

    Interesting idea . . . ;-)

    …later that day:
    …19:18 239V 360mA (20h 43min)
    22:40 240V 360mA (24h)
    cool off for a couple of hours...
    Job done until the Autumn! Have a great summer! :);)
