Battery needs TLC.
Cable Cleaning
The battery cable connections should be cleaned once a year.
The number "my car won't start" problem -- with new cars or old -- is the battery cable connections.
Note: If the positive battery cable is really bad, replace it. Reasons to replace it include:
- Corroded bolt, so cable can't be tightened
- Green corroded wires (white corroded can often be cleaned up with a wire brush)
- Remove the negative battery cable first so that any accidental touch of the wrench will not cause a spark
- Remove the postive battery cable
- Wipe the battery down with a damp cloth. In a glass, mix a bit of Baking Soda with water. This is a base solution which will nuetralize any acid film on the battery. Carefully wipe the top of the battery clean. Dry with a paper towel.
- Dip the battery cable terminals ends in the glass to nuetralize acid deposits
- Use a battery brush to make the battery posts shiny. Alternatively, you can scrape the posts with a flat screwdrive until shiny bare metal is showing all around.
- Use the battery brush on the inside of the cable ends. Or scrape with a knife.
- Coat the bare metal with battery-spray (alternatively, you can use a thin coating of grease or clean oil). This helps protect against corrosion.
- Replace positive cable and tighten to specification (not too tight!)
- Replace positive cable and tighten to specification
- Test for proper car operation, including starting the engine
- Reset the radio presets
