Care to set up a vote on that?
I already have vote per view on, thanks.
People idly clicking on the thread, does not prove there is any interest in your strange thread.
Eh?
Damn, you are very keen on the voting. He's talking about the adaptor repair at the beginning of the thread.
Which was almost two years ago and 14 pages..
My recent battery rejuvenation attempts were not successful. I was trying various approaches and did not retrace my previous steps when things were working. It can be concluded that high voltage alone will not accomplish rejuvenation. What other factor is needed is not yet known. On this occasion, I had been particularly intolerant of gassing. This might have caused the lack of success.
Here are the current state of the batteries:
Powerline 075 435EN (my interpretation: 475CCA) 45Ah(C20), very old
159cca, 13% life, 16.28 mOhm, 12.1v -- discharged from use
363cca, 67% life, 7.14 mOhm, 13.63 -- best of the readings this session
Note: the capacity is largely in line (-5%) with previous result for this battery
Helden 020/019 900EN 950CCA 100AH, ebay new
Actual: 019 810EN 890CCA, the manufacturer's claim was a lie but OK because I did not overpay
859cca, 82% life, 3.02 mOhm, 12.71v -- on delivery
874cca, 85% life, 2.97 mOhm, 12.84v -- during high power charge using 21W 1A adaptor
889cca -- best seen during charging before collapsing from gassing
85Xcca -- stable idle capacity
Note: to be diy respec'ed as 890cca to match the 019 battery from the same manufacturer clamed as 810EN 850CCA
Ebay refurb 027 seller-spec:550CCA diy-respec:600CCA
475cca, 63% life, 5.46 mOhm, 12.24v -- moderately discharged from use
573cca, 91% life, 4.53 mOhm, 13.23, -- best of the readings this session
Note: broken through the brick wall of 550cca seen last time, but far from the best ever seen of 639cca
Lion 063 EN340CCA 40AH, diy-respec:340CCA
0CCA, 3.82v -- flattened from use, had no power to power the battery analyser
247cca, 68% life, 10.49 mOhm, 13.18v -- best of the readings this session
Note: capacity ruined compared to last time. Slightly higher capacity seen in a later discovery

What an exciting life you must have.
Definitely more exciting than that of the people who comment in threads they have no interest in.
I've taken up a new hobby of watching paint dry.
The reason why I click on this thread is because I'm curious to know when you'll move on to something more interesting and worth doing.
It doesn't appear to look like this though.

Very soon. So, hold your breath.

This battery project is taking an exciting turn in direction. Rather than attempting to revive batteries, a better solution is to prevent batteries falling into a poor state. This can already be done by swapping out batteries. But I found that to be tiresome. So the solution is a portable charger. In this prototype, the smaller 063 battery is charging the bigger 075 battery:
With a portable charger, there is not the hassle of mounting and unmounting a battery from the car. The charger will plug into the car and go. The charger will run the sleep mode power requirement of the car as well as charge the car's battery. Once depleted, the charger could be removed from the car with minimal effort. The charger will only be needed in low light seasons where the solar panel becomes useless.
During the prototype test. It was discovered that the capacity of the 063 battery increased from 248CCA to 255CCA during a 2 hour discharge. This proved that to maximise battery capacity, one or more discharging and recharging cycle was necessary.

The plan is to place the portable charger in the driver foot well. It will be taken out when driving. This is not an issue for infrequently driven cars.
The new charger controller is on way. This will be fixed in settings at around 12.8V and 150mA, and be attached to the charger battery as a single convenient package. The car sleep power consumption is less than 80mA. The excess power from the charger will charge/maintain the car battery. The actual amount of charging current will be regulated by the voltage difference between the car battery and the charger. When the difference is small, the charge current will be proportionately smaller.
Tests indicated a voltage differential of 0.05V is enough to induce charging. The gassing resulted from excessive charging at 13.5V was low. It could be even lower at 12.8V.
