12V Battery: what it does & when to replace it
The 12V battery supplies the current to start the engine and powers electronics when the engine is off. Most last 3–5 years. Warning signs include slow cranking, dim headlights at idle, dashboard warnings, or needing a jump-start. Group size, terminal layout, and cold-cranking-amp (CCA) rating must match the vehicle. Replacement is an easy DIY job — disconnect negative first, then positive — but on many modern cars the battery must be registered/coded to the charging system, which may require a shop tool. Hybrids and EVs also have a separate 12V battery in addition to the high-voltage pack.
DIY difficulty: Easy DIY (some cars need battery registration). Always confirm the correct part for your exact build by VIN before buying.
