New Battery Installed But Car Still Dead

 

What Mechanics Check First

Many people replace batteries thinking it solves everything. In reality, electrical leakage is often the main issue.


Things I Check On-Site

  • Alternator output voltage

  • Parasitic drain

  • Fuse box corrosion

  • Ground wire resistance

Pro Tip

If voltage drops below 12V overnight, something is draining power silently.
