Shop the right Car Battery Accessories and Demineralised Water at Repco

Repco stock the best range of car battery accessories and components to help maintain, monitor, and enhance the performance of your vehicle's battery. From simple items like terminal cleaners and demineralised water to battery clamps and battery monitors, at Repco we stock all these and more. Stocking the best from Century, Cole Hersee and more ensures your car battery remains in optimal condition for as long as possible.

One of the most common accessories is a battery terminal cleaner. Over time, corrosion can build up on the terminals, which may lead to poor electrical connections and reduced battery efficiency. A terminal cleaner is designed to remove this corrosion safely and effectively. Similarly, terminal protectors, often in the form of sprays or pads, can help prevent future corrosion.

The Importance of Demineralised Water

Demineralised water plays a crucial role in the maintenance of lead-acid car batteries. These batteries rely on a mixture of water and sulphuric acid to function properly. Over time, water within the battery evaporates, which can lead to a drop in electrolyte levels. Topping up the battery with demineralised water ensures that it continues to operate efficiently.

It is important to use demineralised water rather than tap water because the latter contains minerals and impurities that can damage the battery. Minerals such as calcium and magnesium can lead to the formation of deposits on the battery plates, reducing their ability to hold a charge. Additionally, impurities in tap water may accelerate corrosion, shortening the lifespan of the battery.

When adding demineralised water to a battery, it is essential to follow the manufacturer's guidelines. Overfilling the battery can cause the electrolyte to spill, while underfilling may lead to exposure of the plates, which can result in damage. Always ensure that the water level is just above the plates, and use a funnel for precise pouring.

Keep a healthy battery with the right gear from Repco

Car battery accessories and demineralised water are essential for maintaining the health and longevity of a vehicle's battery. By getting the right battery tools and accessories from Repco, you can ensure your battery performs reliably and efficiently. Regular maintenance, combined with attention to safety, will help avoid unexpected breakdowns and costly replacements.
