Recognizing battery problems early can prevent complete failure:

Difficulty starting: Engine cranks slowly o r fails to start.

Dim o r flickering lights: Headlights, interior lights, o r dashboard illumination may dim.

Battery warning light: The dashboard may display a battery o r charging system warning.

Electrical malfunctions: Power windows, infotainment, o r other electronics behave inconsistently.

Rapid voltage : Multimeter readings show significantly lower voltage than 12.6V when the engine is off.

Distinguishing from alternator issues:

A fully charged battery that drains quickly usually indicates battery health problems.

A battery that drains while driving may point to alternator o r charging system issues.
