We’ll explain the pros and cons of each approach before proceeding.

Alternators typically last between 80,000 and 150,000 kilometres, though this varies by vehicle, driving conditions, and electrical load. Heavy-duty use, frequent short trips, or towing can shorten lifespan. There’s no set service interval—replacement happens only when it fails. Regular battery testing and electrical system checks help catch declining alternator performance early. We can advise you during routine servicing if your alternator is ageing and may need attention soon.

Yes, a failing alternator forces your battery to work harder, draining it faster and reducing its lifespan. Over time, continuous undercharging stresses the battery and can cause permanent damage. If your alternator isn’t replaced promptly, you may end up replacing both the alternator and battery—a more expensive repair. Catching alternator problems early protects your battery. Once we’ve replaced your alternator, your battery should charge normally again.

We use genuine OEM-equivalent parts for Japanese vehicles, which match manufacturer specifications and maintain reliability without dealership pricing.

Turn off non-essential electrical items like the air conditioner, heater, and radio to reduce battery drain.
