Yesterday our UPS finally gave me the Lower Battery indications, it was beeping & complaining several times in the evening.
So this morning I turned it off:
unplugged it,
removed the two 5 Amp 12 Volt batteries,
measured them to determine which was low,
replaced the low one with a newer one from a smaller single-battery UPS, still the same brand & model that's in there - Duracell
accidentally flipped them to make the connections & Voila, welded the Positive terminal to the post/tab so badly that it destroyed it, wrong Polarity!
The problem now is that if I cut off the old terminal & crimp a new one on there, it will be too short to connector, or at least very difficult.
What I did was go shopping & found the F2 spade terminals designed for larger diameter wire:
like the Yellow one,
Now my plan is to cut off the spade part of the old connector, leaving the part that's crimped round the wire & just put the new yellow connector over it & crimp.
Not going to try until tomorrow morning, so thought I'd float this around in here to see if anyone had a better suggestion.
Right now it's working, but what I've done is just jam the melted spade connector on with the tab between the melted metal & the plastic shroud of it:
The original connectors are completely shrouded in insulation, like that^,
but if we're being honest it doesn't need to be, the inside where it goes has no bare metal.
I'm still going to carefully cut that insulator off (just one slit down the middle) & try to reapply it after getting the new spade on there, anyway.
I thought for sure I fried the whole unit for a minute & was about to weep a little, it's a $200 USD unit.
Taking it to a nearby shop would probably cost me about $50 USD. I took a speaker-cabinet there years ago for a new Capacitor in the crossover & they charged me a lot & didn't even use the correct value of Capacitor.
If my plan doesn't work, I'll start making some calls Monday to see who can fix it, & probably still go cheap & do it myself.
Yeah I know, the real fix would be to just run a new wire so it's long enough, but I'm not going to risk tearing this thing apart any further than the battery compartment.
