Car battery booster emits whine that changes when plugged in

i have a Peak jumper pack that is a compressor too. stopped using it a year or so ago as one of the features didnt work, i presume the compressor but i forget. anyway, i wake up today to a steady high pitched noise coming from it. for the fun of it i plugged it in for a second and the pitch momentarily changed. i also tried turning each function on and off and nothing changed. the battery charged life shows nothing when i press the button. no easily determined way to pop it open and disconnect the battery either

i put it out in the breezeway in case it explodes or something but what the heck is this noise?

Maybe some type of low battery warning. Is there a model number on that Peak booster ?


From their website....
Reverse polarity indicator/alarm – Alarm and light if you do not hookup correctly to your vehicle (if hooked up incorrectly your battery could explode)
That's probably what you are hearing with a low battery. Maybe charging it for a while will take care of it. If not the battery may be on it's last legs.

so if i plug it in it wont blow up or anything? just weird sitting in closet over a year and all of a sudden does this and turning any switch on or off doesnt affect it. my bet is the compressor died as i did buy a new one last winter. wouldnt have done that unless i was broken

pkcobj is the model

Probably the low battery alarm
I have a Peak jump starter and they have a little plug (Which always falls out and gets lost) to enable the low battery alarm. To disable the alarm you have to put that little plug back in which as I said probably got lost

Looking at you model the low battery disable plug is right below the charging jack
