Tahoe started struggling to start a little.
Looking at the battery, I see it's 5 years old.
Usually I would just dump it at this point, but then I learned I can sometimes restore a battery using my DC stick welder.
So I yanked that pig out last night and popped the caps off.
I found the fkn water level was low on nearly every cell, I could see the top of the lead.
Topped it off, then stuck the welder on there in DC+ for a few min on the lowest setting and let it boil the water for a bit.
I tried turning it up another step but then one of the cells started boiling over.
Good enough, used a little sucker tool to pull up some of that electrolyte and balanced the cells a little better using it.
So far so good!
Tahoe sounds like it has a fresh battery
So maybe $100 saved.
Then I decided I needed some gear out of my Jeep today, I found the remote wouldn't respond?!
I opened the door with the key and found my dumbass left my bluetooth obd2 dongle installed for the past few weeks.
it still had a single light on, so hopefully the battery didn't totally freeze.
it was dead enough that the interior lights didn't even try to turn on.
I took that super old charger I bought at an estate sale over the summer and turned it on for a few minutes.
Jeep cranks right up like it's fully charged.
I love that heavy ass charger.
The insides look like the DC part of my Lincon stick welder.
