• Freezing of Electrolyte: When a battery is discharged, the electrolyte is mostly water. At low temperatures, it can freeze and irreparably damage the battery.

How to avoid it? • Avoid too short daily journeys by car in winter. • In cold climates, increase the specific gravity of the electrolyte if the battery is open (acid/water = 1.29-1.3 g/cm3). • Switch to AGM or Gel batteries.
