So wondering what all the procedure I need to do to test a battery to make sure it's good before I reuse it. I got a refurbish part coming - the Bguad 3cq3. So once I do what this video shows on this one, i was going to follow his steps. Is there anything else I need to do? How about load testing? that bguad thing seems to charge it back up if its gotten unbalanced but, if your battery module is dead, doesn't like they lose power faster than other modules, putting it back out of balance? Does this Bguad thing do this or, if you don't know, what do i do to test this? Would I hook up a headlight bulb to them and check voltage before and after a set amount of time to them and see if there are any that are losing their charge quickly? saying if I can get my bad modules back up working. Is this about all the procedures I need to do to my battery to refurbish it? Heres a video of mine, the Dr prius app of what i seen. It tells me that module 10 is bad, but what about #4. I can't really tell but it stays low compared to the other bars on that one screen. What can I tell from this screen? Also, near the end of that screen, the #10 starts turning yellow and showing 17V(olts). What is that is that a bad thing? why is it doing that for? Also after I turned off the screen recorder, all the modules starting showing yellow and 17v. Is that over powered? What would be causeing it to do that is that good or what is it doing?
I cannot edit my post but I had to reupload my video. (edit: ok rewatching it, its not the same guy as the first. I just want to be careful and not swell the packs. I guess just letting them cool down overnight before removing them is what to do? Tired..) So question Ive got, I ended up searching more of load balancing/refurbishing the batteries. The guy who's video I linked to up there, I ended up finding more videos of his where he showed he had swelled his batteries. he showed he used longer bolts and tightened them down over time to squish them back together. How do you keep from ending up swelling your batteries? Is there some trick to it? did he over do it? or did he just not maybe let them cool down enough? What causes batteries to do that? I know there in that case to keep them from bulging out in the first place, but you can open the pack, replace a bad module or 2, and put it back together without that happening. What can I do to not do that to my batteries? Did he do the refurbishing wrong? the questions ive got is, what method should I use to refurbish the batteries? Is the method in the first youtube video I linked an ok method to do it? What do you watch out for to not swell your batteries? And also from when Ive bought "new" batteries for my phone before, you can mek them show a full charge sure, but then you put them in and they run down quickly. I would guess a load test would be what to do on them. - is that method in the first youtube link work to do all that without needing to get a headlight bulb out and run them down and time them? What would I do for the full procedure. I guess maybe I havent searched on this forum enough? but is that first video I linked, got it all in there? refurbishing and load testing? and what do i need to watch out for to not swell the batteries (as what happened in that first video link). like what do you guys think he did precisely. just didn't let them cool down enough or all the way before unbolting them ? or didnt show a step in his video and he didnt let it cool down or something?
