HAZI.ro - New problems, new solutions

Derp, my UPS is tits up. Gonna buy new tits new batteries this week at a scrape yard. They were 10€ each last time. One of the batteries is all corroded and only shorts at 200A instead of the nominal 500A, this doesn't mean anything per se but I'll make it mean that it needs a replacement in lieu that the UPS as a whole doesn't hold the computer powered on for long. It was a graceful death nonetheless because the batteries still hold the computer on but only for 30 seconds. I mean they still work a little...

Post photos after you assemble that abomination. Be sure to indicate capacity and all that kinky welding. I bet you weld like folks on aliexpress

No solder joints, I keep the 500 amperes wires clamped together by the weight of a heavy propane tank. Next to the dynamite shelves. In the bedroom.

Okay this is the old pic:

Right now it's really tits up in that same room. It's a mess I can't even step in.

We are happy to announce that today we purchased a new UPS that will solve the problems of the last few days, problems that we talked about in the previous announcement.

The delivery of the new UPS will be made in a maximum of 5 working days.

(emphasis mine)

Just a short remark: wouldn't it be better and smarter to either word it a bit differently ("...we think will solve") or to simply declare success only after delivery and at a very minimum 24 hrs. of testing?

I get it, you approach it optimistically - but exactly that, declarations like the above, will (understandably) invite laughter and sneering if the new UPS does not solve the problem or someday fails.

The success was declared a bit early but based on identified root cause.
Now after about 3 weeks with 0 downtime, i can say that I was not wrong this time.
Thanks for your comment!

This made my day. Big fan calin. Know you since you started selling swap as ram and lying about your age. Oh and remember when someone used to mess with your website like 5 years ago? That was ghita, I was in a call with him. But I can say you've made some progress.

Telling customers you won't invest 1000 to 5000 euro just so their machines aren't annoyed anymore is crazyyy. There's no way a real business would straight up announce they are aware of the issues but won't fix due to the "high" cost. This screams basement more than calin's. And that's probably a more remote area, cause here in Bucharest the power is pretty stable and usually goes down like 2-3 times a year.

Hetzner cloud prices for what? Just seems like you should cater to non experienced people, not lowendtalk

Wait what?! Swap as a ram? Maybe a link to a thread with this gold would be good.

Real men use Google Drive as swap and mounted storage.

You mean AWS glacier?

Eventually, when you'll need to replace the batteries, there are these cheap testers that give a good clue about the conditions of the batteries. I bought this:

and tested my two UPS batteries:

These are both 48Ah flooded lead acid, with a small circuit to reduce the charging voltage from the UPS, which expects AGM batteries instead; you can see that one battery tested at 225 CCA but the nominal current is about 500A, so it's quite worn out. The lead plates are etched and this battery needs a replacement.

These batteries lasted 5 years mounted on the UPS and were second-hand even back then. Not a bad longevity but they could last even longer by reducing the trickle voltage.
