My car is at 71,000 miles and the lead-acid cell under the hood needs replacing.

While in an extended FAS in the middle of the night my headlights dim down to almost useless after a few minutes.
Restarting the engine blasts them back to full.
At the end of a long FAS if I turn the steering wheel hard power steering is jerky and the radio cuts out and my air horn blows only one horn.

Last Spring I was parked on a store curb waiting for my wife to come back. I had the engine off, headlights on, blower set to high and the radio on.
I had to wait probably 35-40 minutes and when I tried to restart-
All I heard was a clicking sound like an old starter relay on a dead battery.

A couple more key turns and she started right up. IMA battery was normal full.

I'm sure I just need to go pick up a new lead-acid cell.

Efficient drivers do it better.
