Regular testing and inspection will help to maximise battery life, a routine inspection at least once a month is recommended to maintain optimum performance.
Use the following checklist as a guide when examining your battery:
1. Ensure the Battery top is clean, dry and free of dirt and grime. A dirty battery can discharge across the grime on top of the battery casing.
2. Inspect the terminals, screws, clamps and cables for breakage, damage or loose connections. These should be clean, tight and free of corrosion.
3. Apply a thin coating of high temperature grease to posts and cable connections for added protection.
4. Inspect the battery case for obvious signs of physical damage or warpage. This usually indicates the battery has overheated or has been overcharged.
5. Check electrolyte levels to ensure that fluid levels are over the top of battery plates. If necessary top up using distilled or demineralised water. Never top up fluid levels with acid.
6. Test the battery using either a hydrometer or voltmeter and charge if necessary.
