Preventive Maintenance

Maintaining your auto battery is the most important thing you can do to ensure you never find yourself stuck with no charge left. Here are some tips from the experts at SuperCharge to help you keep your Honda, Mazda or Holden battery in good condition.

Causes of Failure

Lead acid car batteries primarily fail when a process called lead sulphation occurs. The plates within the units become coated with lead sulphate or, if tap water is used to fill the unit, calcium sulphate. Essentially, this slowly reduces the capacity and once this process runs its course, the unit “dies”.

Car batteries can also fail as a result of:

  1. Deep Discharges
  2. Vibration
  3. Heat
  4. Undercharging
  5. Non-Use
  6. Overcharging

 

Heat and cold can also have an impact on the lifespan of your Mazda, Holden or Honda battery.

In warmer temperatures, positive grid growth, negative grid shrinkage, plate buckling and water loss can cause failure.

Cold temperatures affect units differently. The expansion and contraction that occurs during the discharge and re-charge cycle can “age” the unit as the active positive plate material sheds. This shedding leaves brown sediment at the bottom of the case (often called “mud” or “sludge”) which can short the cell out.

Accessible Unit Maintenance

SuperCharge recommends the following measures to protect your car or truck’s unit:

  1. Ensure water levels are maintained. Fill only with distilled water to a level a half inch below the separator. The plates within a battery must remain submerged at all times to remain functional. Do not overfill, especially in hot climates, as the fluid can expand and overflow.
  2. Routinely remove any corrosion that may build up on the cable or both terminals.
  3. Check the tension of the alternator belt.
  4. Ensure the top is kept clean and the hold-down is secure.
