alright so I bought a charger for my mustang battery. its been on there for a bit, I took it off and used a multimeter to check numbers. now im no electrician, so heres a pic.




on this setting that you see, it read around 24. now I checkes the same setting on my cobalt, not crunk but still hooked up and got around 26-27. am I doing it right?

 

just leave the charger on the highest setting for an hour. that's why I did with my cobalt battery. needless to say I had to buy a new batt recently. lol

in because im bored

 

Turn it to the left to 20v and try it

 

Should have the multimeter set to 20v DC, at the other side of the scale.

 

In for results

 

on that setting it reads 11.66

 

This. In this setting it will give you a correct t readout. Since you charged it and it read 11.86 then you probablyneed a new battery.

 

pics of mustang lol

 

well it wasnt on the charger long. just wanted to see if it was making process and what the reads were



.2002 mustang v6 105xxx miles


thats where you can see pics. its nothing special, and its sold pending payment.

 

needs a paint job, lol If its sold already and getting paid, just go to walmart, or like a costless autoparts, and buy the cheapest battery possible, even the cheap ones last around a year.

 

well this battery is less than 2 months old lol. and it wont be paid for til the end of the month.

 

Put the charger on high and charge for 35- 40 mins and then check it.should be around 12.5v .

 

well its a cheap little charger. said it s good for car batteries but theres no switches. just Connect and go.

 

Yeah nothing more than a basic tricle charger. It will take hours depending on size of the battery... plug in and go watch a movie lol

 

haha yeah thats what ive been doing. just passing time til its done.

 

ur battery is probably well fucked and now unusable. Put the charger on the lowest setting and leave it like that for several hours.

 

im getting an 11.66 right now but the moment I unhook the charger i can watch it start dropping to lower numbers. battery went bad?

 

and I checked the cobalt, hooked up but not running it has a steady 12.55

 

put the battery in the car, all the guages came to life. battery guage was halfway like normal. turned it over one time and zapped all the juice out of it. all the lights/guagew went out. hookes up the cables to the cobalt, mustang fired right up. shes running right now. so looks like im taking this battery back to my guys and having them fix it. I crank that car at least once a week, and the battery is two months old. is it feasible that the battery is faulty or just thats how they get killed?

 

if the highest you get is 11.66 while charging and it immediately drops they battery is gone. i have only seen a hail mary work once where a battery was on charged at 1a for like 30 hours that came back to life but it was a deep cycle AGM battery that was basically new. you can try it but with the high amperage charging you have done idk if it will work for you... highly improbable

 

In for the update

 

this is some napa battery, just an fyi.

 

Battery is bad
