What Level Should You Fill Your Car Battery To?

When it comes to maintaining your car battery, one important aspect to consider is the level of battery fluid. The battery fluid, also known as electrolyte, plays a crucial role in the overall performance and longevity of your car battery. In the United Kingdom, it is essential to maintain the correct fluid levels to ensure your battery functions optimally. So, what level should you fill your car battery to?

In the UK, most car batteries are sealed and maintenance-free, meaning they do not require regular fluid top-ups. These batteries are designed to be completely sealed, preventing any evaporation or leakage of electrolyte. Therefore, there is no need to fill your car battery to any specific level as long as it is a maintenance-free battery.

However, if you have an older or non-sealed battery, it is important to check the fluid levels regularly. In this case, the electrolyte should be filled up to the designated fill line indicated on the battery casing. It is crucial not to overfill the battery as this can lead to acid leakage and damage the battery and the surrounding components.
