Your K20 doesn't have an expiration date, but its battery does. The average car battery lasts three to five years. Don’t get stranded by your K20’s car battery. Replace it regularly instead! Watch for signs that your current battery is getting too old or too weak. A slow engine crank, an illuminated check engine light or battery signal, swollen battery case, corroded battery terminals, or faded headlights can all be signs that your battery is on its last leg.
