Buying a Replacement Battery for Infiniti Q45

Sadly, your Infiniti Q45 won't last forever. Neither will its battery. On average, auto batteries last anywhere from three to five years. Check your battery regularly and replace it as needed so it doesn’t leave you and your Infiniti Q45 stranded. Pay attention to clues that your battery is on its way out. A lagging starter, an illuminated check engine light or battery signal, swollen battery case, corroded battery posts, and subpar electrical performance may all indicate that your battery is on its last leg.
