MAINTENANCE AND CARE

It is essential to keep your battery regularly charged throughout the year, especially during
the winter months. In the winter the effectiveness of your car battery is reduced by the cold.
Oil is thick. Engines are difficult to start as the heater, windscreen wipers and lights are all
draining power. It is at this time that batteries have to be at peak power. If your battery is not
regularly maintained and kept fully charged, it can cause problems and a possible breakdown.
Listed are some helpful hints on how to keep your battery healthy in conjunction with your
Battery Charger.
Faulty Cells
Batteries are usually made with six cells. One of these cells can deteriorate or get damaged. If,
after several hours charging your battery is still flat, you should test the battery. Take
hydrometer readings from each cell in the battery. If one reading is lower than the others, this
could indicate a faulty cell.
