Electrolyte Level

If battery electrolyte level is allowed to drop substantially, the gas volume inside the battery grows proportionately resulting in an increased amount of flammable gas mixture. Any external or internal spark may result in an oxyhydrogen explosion. Additionally the plates are no longer covered by the electrolyte and may corrode.

The battery electrolyte level should be checked on every Inspection I and Inspection II.

Use only distilled water to top up the battery!

Tap water and electrolyte must never be used to refill or top off an automotive battery.

Workshop Hint: 

Electrolyte levels may drop at a higher rate in the winter months, due to higher loads and increased utilization of electrical systems.
