I let almost all my items sit on a cold concrete floor for a few weeks minimum if I feel there is any risk associated .

Be safe ! Enjoy that thread .

I think you have the order backwards , if I fear somthing having a charge , I leave it sit BEFORE I tear into it . My experience with monitors at least . Please be safe .

With battery backups and various computer power supplies they can and do sometimes hold a residual charge. IN a UPS yes you need to remove the battery first. After that you can discharge it by attempting to power it up or plug in a load OR like metal said above me, leave it alone for a while. Most electrolytics cannot hold a charge for more than a few days. But some high end caps can hold a charge for weeks. Just take it easy, work smart, don't take apart anything that was just plugged in.

What about when i break it down, don't those transformers hold HUGE power surges for days on end?

It's not usually the transformers but the can capacitors that can hold a charge. There is supposed to be a discharge circuit built in on a lot of electronic's but you could be risking your health/life to some resistors/transistors that may or may not already be blown and not capable to do their job (which is to protect you).
