UPS as source for transformers ( was Re: Transformers: was Power supply question

If you open one up and there's a bunch of batteries in there, they're

rather than replace them, they get thrown out and buy new. Also
while your in there look at the circuit board and you may also find a
NTC thermistor, I got a 30 Amp one from the big supply.
