Warranty Information

Peace of mind

Each Yuasa Battery is supplied with a warranty against defects for the period and application, as detailed on each battery.

Call 1300 361 196 for your nearest warranty claim location.

Proof of purchase is required.

For valid claims, Yuasa will replace the product free of charge.

The warranty excludes defects from after sale damage, neglect, abuse or incorrect installation. You bear all transportation costs to and from the warranty claim location.
 
The benefits of this warranty are in addition to any other rights and remedies available at law.

You are entitled to a replacement or refund for a major failure and for compensation for any other reasonably foreseeable loss or damage. You are also entitled to have the goods repaired or replaced if the goods fail to be of acceptable quality and the failure does not amount to a major failure.
 

Using electronic battery testers

There are a diverse range of electronic battery testers available and whilst all will give a test result, they should not be used as a definitive answer to determine whether a battery is faulty. Different makes and models of tester may give a different result based on their calibration and as such should form one component of the battery test procedure.
 

This warranty does not cover

  • Normal wear and tear
  • Physical Damage
  • Sulphation
  • Incorrect application
  • Negligence (before or during use)
  • Overcharging
  • Failure arising from the addition of fluids other than water
  • Batteries used for motorsport or racing activities
Yuasa batteries are manufactured using processes conforming to the nation’s leading Automotive Manufacturing quality assurance accreditation.
 

Why do batteries fail?

Batteries have a finite life, determined by the application and the operating conditions. Battery failure can be attributed to various factors, however the causes of failure fall under two distinct categories: manufacturing and non-manufacturing faults.
 

Manufacturing faults

Typically occur within the first 3 months
 

Short circuits/dead cells

Where one cell will show a dramatically lower Specific Gravity (SG) reading than the other cells.
 

Internal break

Usually resulting from physical damage to a battery during transportation.
 
Yuasa’s stringent quality assurance and inspection processes demanded by leading vehicle manufacturers ensures genuine manufacturing faults in Century Batteries are negligible.
 

Non manufacturing faults

These fall outside of Yuasa's strict quality control systems and are more likely to occur the longer the battery is in service. They are often attributed to a problem with the vehicle’s electrical system, its operation or the battery application.

Wear and tear

As a battery ages, grid metal corrodes and active material is lost from the plate. Over time this leads to a point where the battery will no longer be able to start a vehicle. High temperature will accelerate the degradation rates.

Physical damage

Incorrect fitment, handling and storage often leads to external damage and subsequent battery failure.

Incorrect application

Fitting a smaller, less powerful battery or a battery designed for another application can lead to early failure.

Negligence

Failure to maintain fluid levels exposes internal components and accelerates battery failure.

Sulphation

Occurs when the battery is allowed to stand in a discharged state for an extended period of time.

Over-charging

Often caused if the alternator is incorrectly set or the alternator voltage control fails.

Under-charging

Short journeys, stop start driving or faulty alternators will not fully recharge a battery.

Discharge

Lights or other accessories left on for extended periods.
