So here is what you can expect to find inside a server UPS.

CHeck out the size of this trasformer!!!

Got about half pound of 55% wire as well and 3# low grade board.
I found a transformer like that in a fruit machine once. All the copper was baked into a plastic, and stuck fast. Did you bother to strip it or sell it as it is? I tried smashing a hell out of it, but it wouldn't budge.
I am just going to sell it whole
No brass to speak of?? Mike.
Didnt see any in the one I took apart.
I took one apart takes ages and not worth it. Once you remove the tape and takje off the coiled copper, underneath there is more tape would round, take this off and remove the copper underneath and there is more wound tape.... Didn't get much copper from it compared to it's original weight and would have been similar if not worse price had I not just taken it in as is. The reason why it would smash is because it's not cast iron. It seems to be a plastic covered steel sheet wound round like a big roll of sellotape would be.Quote:

Did you have to discharge the batteries in this? I am getting 4 soon, don't want to get a bad zap from it
You should be able to just disconnect the batteries and be safe. Once the bats are out, there is no more power.Quote:

I did cut the cords on one and discovered that the batteries had a charge. No shock to me but a big spark so take care. MikeQuote:

Those are one of the easiest transformers to strip. You take a grinder and grind around the side then the copper and plastic just peals off. Takes about 2 mins.Quote:

Most UPS's I scrap have swollen batteries and the only way to remove them it to take the UPS apart.
What did you do in that case Jimirick?
After disconnecting the batteries, discharge any electrolytic capacitors (metal cans) FIRST.
This will help avoid a zap.
Just cross them with an insulated screw driver?Quote:

That 23 lb coil is a toroidal coil worth much more than scrap to those who tinker with high voltage electrical experiments such as tesla, try eBay.
Perfect, I've read up on it and quite sure I get it. Just need to bridge the positive and negative terminals. Time to go get those battery backups from my neighbour :D
