I have seen that a few times...usually only in batteries that already have plates shorted out and can't be recovered. Seems that any shorts between plates get...
Have you opened up the top and added DI water.you will always need to..use a syringe, add DI water till you can see the water surface above the glass matt..let...
Ah, but pulsing a dry cell isn't gonna do you any good either ;-) Take a bad battery > Add water > Test > Pulse >Test JUST adding water does improve things ...
I just got the resisters yesterday, can you email me instructions? I know you remove L1 and L2.what from there? Best Regards, Derek Calanchini Owner Creative...
... Also remove the large capacitor (C4) and C5 it it is there. Now put the resistor in place of the diode; it will now work at Couper speeds (1kHz) Change the...
At the moment I am trying to recover a battery with a swollen (but not shorted) cell, as I feel it would be somewhat conclusive if the swelling was cured. So...
Swelling usually means It will never come back..fully charge it, if it gets HOT - it's a gonner - Once you fully charge it and disconnect it from the charger,...
Using your 12.8V for all cells healthy would translate to 10.7V if one cell was shorted. This battery was resting a good long way above 10.7V, and the swelling...
Given that we can't get do to desulfation times of a few hours (at least not yet) I still think there is a place for an ultra cheap circuit that one can just...
With a tiny transistor and resistor (1mA isn't going to generate much heat) the whole thing might be rather compact and cheap, and at 1 kHz might work about as...
As suggested, rehydration is an important part of recovery, so I have added water to my test subjects, and my initial impression is that recovery may be...
Maybe I deceive myself, but the slight swelling seems to have gone down, Regardless, we still don't have a system that can recover batteries on the order of...
I have only now noticed that the 555 running at high speed has pulled its supply voltage down to around 8V; this does not seem to have been an issue at Couper...
Strangely I have noticed that the peak pulse readings tend to be higher in the morning than later in the day. I can only imagine it is a sensitivity to...
On a reasonable battery I seem to be seeing about a 0.1V reduction per day in peak pulse voltage, but this is a little hard to see as the voltage can very by...
I went on vacation for 4 days, so left the pulser unconnected; resuming upon my return I found the peak voltage dropped 4 days worth... as if some process was...
... Yes it does, and the very act of pulsing a battery heats it up. That's one reason why a change in pulse amplitude does not necessarily indicate recovery. ...
True, there are many contributing factors. But at least the peak pulse height has been dropping. It would be really nice to know how fast it drops with...
... So hook up an inductive pulser and see. What someone else sees on a different battery is not necessarily what you would see on your battery. You seem to...
