fixed a failed car battery!

[Matt Gruber]

72 went dead! 2.2v!
cut hole in top
failed connection between 2 cells. looks like a rivit broke.
drilled hole
1/4-20 bolt.
12.71v fixed!
1st time i've done this!
dangerous acid, don't try this at home LOL
how much current can a 1/4-20 bolt handle? 200a needed to start.

UPDATE:
it only lasted another 6 months(6 years total).
not worth the effort.
But, another wal-mart 12v just past 8 years! still works! not bad for $29
