A while ago, my car wouldn’t start. Not enough juice.
I had to have start help from Falken. The guy tested the battery and said it was fine. But if the car was left standing for maybe a day or two, it wouldn’t start. There was some juice on it, but not enough to start.
We did various tests. The first prevailing theory was that something in the car was leaking electricity. So I took the lead off the positive pool when I left the car. Still, the car wouldn’t start.
Turns out one cell had died. Which means that there wasn’t enough to start the car unless I had help or it had run recently. But once the car was moving, it was working fine.
So I bought a new battery. One of those who won’t leak even if you turn it over (not that you would, of course). And there’s a big difference to how the car starts now compared to before, even before the old battery went bad. True, the new battery is stronger by type, but even so…
Just thought I’d put it out there. There are several ways a battery can turn bad. Of course, mine had been drained recently by the lights being left on by a thief who tried to steal the car and failed. I’m guessing that may have contributed to it going bad.
