Battery maintenance (Renault Megane 2)

To ensure that your battery lasts longer and maintains its maximum capacity, the following conditions must be met.

The battery and its surrounding parts should be kept clean. The surface of the battery should always be dry, otherwise surface leakage currents may occur between individual cells, causing the battery to discharge itself.

The electrolyte level should always be at the ring located on the bottom of the filling chamber. Distilled water should be used for topping up.

In cold weather, do not leave the battery uncharged, otherwise the electrolyte in it will freeze. Weakly charged batteries freeze already at a temperature of about -10°C.
