Battery Care & Safety Tips

Batteries are sensitive to temperature extremes and don't like to be left to go flat.
Just a week without charge can be enough to sulphate and permanently damage a battery voiding its warranty.

Check that all cable connections are clean, tight and free of corrosion.
This will ensure that you get the maximum amount of voltage to your electrical system and your battery receives optimum charge.

If a battery smells like sulfur, is hot or looks swollen, it can be an indication of the battery being over-charged and a risk of explosion.
Do not keep driving, turn off the engine and do not disconnect or touch the battery until cold.
