We sure do need eggs Dave, for more than a month, and I still haven't been able to come over and get some. It's been that way lately with me.DavidBarkey wrote: ↑Fri Apr 29, 2022 5:22 pm When ever you can . I sure you will need eggs soon anyways .

Re: Battery Desulfators
Here's the results from last weeks desulfating. Test#4 results below are the new results.
Batteries 1 & 4 were desulfated for 24 hours. Batteries 2 & 3 were run to the desulfators low voltage cutoff (less than 24 hours). I also let the batteries sit disconnected from the charger and each other overnight before checking the capacity. Results are still not looking better.
Battery #1 (jump pack battery) test results:
Test #1 3.07AH
Test #2 2.95AH
Test #3 2.85AH
Test #4 2.50AH
Battery #2 Inverter battery #1:
Test #1 0AH, ran about 10 seconds under 1A test load.
Test #2 0.18AH
Test #3 0.14AH
Test #4 0.02AH
Battery #3 Inverter battery #2:
Test #1 0AH. Cannot support the 1A test load. Battery voltage drops to ~9.5V when the test load is applied.
Test #2 0AH, ran about 5 seconds under 1A test load.
Test #3 0AH, ran about 10 seconds under 1A test load.
Test #4 0AH. Does not support 1A load. 1A load = 9.x Volt when the load is applied.
Battery #4 Inverter battery #3:
Test #1 3.41AH
Test #2 3.9AH
Test #3 3.73AH
Test #4 3.15AH
I've got test #5 in progress. Battery #4 is powering the desulfator through a diode while the desulfator is connected to either battery #2 or battery #3. Battery #3 will not run the desulfator after sitting overnight but it ran for 24 hours while powererd though the diode from battery #4.

Re: Battery Desulfators
Below is the updated test data for test runs 5 & 6. Doesn't look like I'm making any progress. For test runs 5 & 6 I let the desulfator run until the batteries died. I did experiment with a good battery powering one of the 0AH batteries through a 600V diode. Seemed to work ok. At some point I will experiment using a conventional bettery charger (transformer + rectifier based) instead of the modern smart charger I'm using.

Re: Battery Desulfators
@MattA thank you for the detailed report. I have to say I'm not so impressed with my desulfator. I was going to return it but due to my dragging my feet about it the return window has closed
Oh well
Oh well
