I could be wrong, but I think you are somewhat misunderstanding what Chops is saying. Maybe a little more abuse, but I take it as time saving.
MINE FAILED when I put the batteries in at a mostly charged state and then the Opus discharged, then tried to charge them @ 1amp but reset instead!
INSTEAD of Charging/discharging and charging for the CHARGE/TEST. It save s time if the batteries are mostly charged or at rest after charging then put them in for Charge/Test. that way you save ~ 3 hours.
The Opus is still discharging and charging so you can get the capacity. My failures have been shortly after discharge when the batteries are @ 2.80v and they begin charging again.I believe the INITIAL charge has nothing to do with failure shortly after the battery is discharged.
Again, where mine failed is what HKJ talked about where the charger spikes in output because it needs that surge of energy when the batteries are ALL @ 2.80v. I think he said it jumps to ~ 6 amps for 0.03 of a second!! He elaborated on that last Friday.
EDIT: Besides ALL of that the Opus should be able to do ALL Three stages without an issue!
Jon from Liionwholesale who sold it to me has about 5 of them running constantly doing capacity tests!
OK, I did misunderstand how you were doing it. I thought you were letting the OPUS do the whole thing…… CHARGING almost empty cells - then DISCHARGING for Capacity - then going back into CHARGE Mode
My bad, I’ve got it now. You and chops728 are on the same “program”. It is me that is different as most of the time I did it as described above.
Soooooo…… that tells me that part has nothing to do with the problem…… :+1:
I also need to say!!! That I have done it both ways[no wise cracks I LOVE woman!].
I already mentioned that when I get Brand new batteries I make sure the Opus charges it from the beginning. Older batteries for the FIRST test I may have them charged, but no more than 4.10v so the opus can top it off to where it is accurate for ALL batteries and ALL capacity tests in the Opus.
However,the recent failures the batteries have all been mostly charged and then the Opus tops it off, goes to discharge and then charge.
The mail use to come b/w 1 and 2pm,now after about 3 or 4 mailman changes over the years, It comes b/w 3 and 5! A Flashaholics nightmare! :person_facepalming:
I wanted to get this test done b/4 8 pm when I go on my nightly hike w/ Capo. Does not look like that will happen as it takes about 4 hours,it will take 1 hour just to top the batteries off!
ok,everything is in order!! Came 10 minutes ago,batteries charged in 2 minutes and went into discharge mode,It should be done ~ 7:45!
I will give a report when it’s done! I really hope this is the solution!
I bought 2 Power supplies in case one did not work!!!,the first one did not leave Calif. yet and I ordered that 12 hours before this one that came from Portland, Oregon!
I ordered Two different Power Supplies just in case for back up. One Friday night,that will not be here until Saturday!Of course the Supernight which arrived in 2 days!
Durability and longevity is yet to be determined,so far so good on day #2! I expect my Third test result to follow suit. That should be done by early evening b/4 CAPO and I go on our hike.
There is another way to look at getting one NOW. If your doing a lot of capacity tests the worst that can happen is you lose $6.99 if it fails! On the other hand you can let Wolfdog be the Guinea Pig and see how durable and reliable it is. Then again, I may only run One or Two more CHARGE/TESTS in the next few months!
Confused?! YOU MAKE THE CALL! :person_facepalming:
Yep Woldog, so far you have been a good “Guinea Pig” with some good results. … :+1:
I am glad this appears to have been the problem. Kudos to you & your testing.
But me confused? Not sure what you are getting at…. but never in your wildest dreams am I confused about this.
And be most assured…… I will make the call when I get ready. Whether that be in 5 minutes or 5 years. It is not a though this is life or death ya’ know…….
