Mitsubishi Lancer Owners Manual
Checking battery electrolyte level
The electrolyte level must be between the specified limit on the outside of the battery. Replenish with distilled water as necessary.
The inside of the battery is divided into several compartments; remove the cap from each compartment and fill to the upper mark. Do not top up beyond the upper mark because spillage during driving could cause damage.
Check the electrolyte level at least once every 4 weeks, depending on the operating conditions.
If the battery is not used, it will discharge by itself with time.
Check it once every 4 weeks and charge with low current as necessary.
► For petrol-powered vehicles with turbocharger, the battery upper cover does not need to be removed to check the battery electrolyte level.
