OK
I screwed up twice this month, and it cost me 💸 💸 💸 . But working on a used UPS I got...
Almost electrocuted myself doing the DIY wiring (12awg with flat/curve ends appropriate)
The lead acid batteries are audibly sizzling when attached to the UPS and charging
The UPS itself is dinged up real bad, but works..
So just cut my losses and ecycle the UPS and batteries (despite the bats being NEW) because I don't think batteries are supposed to make SIZZLE AND POP noises when being charged.
Unless any #electricians or #electrical engineers want to chime in, I think the batteries and UPS are all going in "ecycling" cause yeah. doesn't seem right and no way I'm getting a refund on the batteries now, and I don't feel it's a good idea to resell them used despite being brand new?
Kudos to the appliance repair guy who instructed me to have my husband come home from work to… turn off the circuit breaker, in this year of two thousand and twenty three when it’s literally on the wall 4 feet away and gods help me what human doesn’t know how to flip a circuit breaker it’s a basic life skill?
An easier and more exciting way to do it (for the high voltage panels I work with) is to simply toss a screwdriver towards the terminals you're not sure are hot or cold and see whether it klinks harmlessly to the floor or POP 💥⚡💥
I have a collection of partially melted screwdrivers, and also I am still alive.
