Drained or Dead Battery in a Chevrolet Impala

The most common reason a Chevrolet doesn’t crank is a dead or drained battery. Your battery delivers the initial burst of electricity to turn over the engine and get it running.

Indications of a dead battery:

  • Silence upon turning the key – no clicking or turnover
  • Accessories not powering on
  • Difficulty starting in cold weather

The Fix: Keep jumper cables on hand in case of a dead battery emergency. Jump starting your Chevrolet Impala using a good battery or jump box can supply enough juice to get it started.

You can also clean dirty battery terminals that are blocking a good connection. If problems persist, have your battery tested – it may need replacing if worn out.

Faulty Alternator in a Chevrolet Impala
