I just wanted to pop and say thank you, for me the most useful part of this video was how you explained the result of going + or - For me I had already done this, but misunderstood the meaning of the voltage value and was actually going the wrong way, and still seeing an over voltage on my batteries. It was because I was going the wrong way! Thanks again!
That battery bank makes the failed batteries (12v7Ah) in my Trust and Tripp Lite UPSes look like lego bricks, and I would find out they had crapped out when there was a powercut last night... :P
great video! hey uncut is my style, I tend to do short videos anyway so if i mess up I just redo it. I love your ups on a ups setup lol. I really need to have a proper play with the ups' I've gotten to get things going well, all I have done is just put one with 350WM (Watt minutes) of capacity in light load service (Lenovo tiny pc at work) and chucked some new batteries into a BR1500LCD at home (not even serialled into my gaming desktop that it backs up). Anyway good luck with your job!
As for the batteries in storage, you should definitely recharge them every once in a while, maybe twice a year or so. If they go flat through self-discharge or parasitic draw from moisture etc., they can lose their capacity rather quickly.
Have you tried using a contraption that's known as an "Re-EMF charger" on one of your lead-acid batteries? It is claimed to actually improve the battery's capacity by breaking lose sulfates from the lead plates with high-voltage spikes at a rather high frequency (while not heating the battery up during charging). You can find plans for it on the internet.
I've done videos on battery desulfators, you can find some of my findings in my lead-acid playlist. My experience is that they don't do much - and they certainly wouldn't do anything to these batteries, as they've never been subjected to sulfation.
OK. Still, this thing called the "Re-EMF-Charger", basically a "Joule Thief" circuit wired in between the charger and the battery is to my knowledge the only thing that can bring low capacity batteries back up (even though not to full, this seems impossible right now). So if you want to look into it, I'd appreciate your thoughts about the matter.
I've designed a way more sophisticated version of that for use in my testing, and my position still stands. The data I gathered from the big batch of sulfated batteries I used in my "large" test showed no significant advantage to a "re-EMF-charger" over just starting the charge with a controlled overvoltage.
love your video`s and experiments! i just started with a used 3000VA RMI2U unit included the optional NMC card, no idea yet how to start setup, the manual doesnt say so much aboutthe use of the usb, serial RJ45 or the NMC card.... so 3 options i have to control this unit? i ordered a new RBC43 batterypack as the old one doesnt seem to handle the load for long, it drops within 10 seconds to about 20% charged and the ups flip with shutdown and start over and over. i did the test with 900watt coffeemaker so a really usefull load for a test, a server wouldnt be happy to get power on and off that fast lol , any tips what to do ? i sure want to lower the chargevoltage when my new batterys arived. Now the batterys doesnt seem to accept much amperage , messured around 180-260 mA only while the ups indicated after 3-4 hours the batterys are 100% charged..... i not really believe that. Cheers m8!
You need to hack into the internal serial port if you want useful console access on one of the LCD models. Then it's just a question of entering the programming mode (press 1, wait 2 sec, press 1 again) and altering the battery voltage variable (capital B) by pressing +/-.
having hard times to get it work with apcupsd, i run now usb cable and network to the nmc card , powerchute business and the webgui from the nmc too. all that works fine. what left is the rj45 port (serial) have no cabling for that , but wonder if its not easyer to add some lines the the apcupsd config instead ? having hard times with commands-) for now i have a brandnew batterypack and charging is about 54,5 - 54,8volt that comes at max 13.7 volt/battery as i have 2x4 in serie /parrallel , seems not too bad but little lower might be more perfect

Hello FFcoassag, which cable you connect to programming? software to do that and where to download software and where to buy the cable. Thank you
Good to see you have a real circuit breaker for those batteries, not some small cheap thing that cannot cope with the high fault currents.
600 V DC rated, baby.

Do you need a special serial cable for them UPS , like an isolated one . Or can you just wing it with a null modem one ?
APC UPSes always need special cables. There's a couple different versions, the SMT series I think just has an RJ-50 on the back for extra headache.
for APC UPS TTY mode calibration is there exists any manual?

I take care of my batteries, they're my children.
LOL, OK then.

I have had a set of 4 powersafe batteries. one by one they all would lose capacity :( 2 low 1 quite low and one dead
What laptop are you using?
it looks like an hp probook 6570b
The Probook 6570b that we picked out of the trash and fixed on a livestream a while ago. It's nice as it has a serial port on the back.
So why did you choose to live up North in the dark?
I was born here, and home is where the heart is.
If you just need quick video trims or edits check out avidemux, it can trim instantly without re-encoding.
Cool, I'll have to check that out.
Dam good without editing :-).
Most batterys need a good workout to be healthy, dont know about yours.
"Work" Disgusting lol :-D
