Lanos S Sedan L4-1.6L DOHC D-TEC MFI (2001)
Battery: Description and Operation
Built-In Hydrometer
BUILT-IN HYDROMETER
The sealed battery has a built-in, temperature-compensated hydrometer in the top of the battery. This hydrometer is to be used with the following
diagnostic procedure:
1. When observing the hydrometer, make sure that the battery has a clean top.
2. Under normal operation, two indications can be observed:
-
GREEN DOT VISIBLE - Any green appearance is interpreted as a "green dot," meaning the battery is ready for testing.
-
DARK GREEN DOT IS NOT VISIBLE - If there is a cranking complaint, the battery should be tested. The charging and electrical systems
should also be checked at this time.
3. Occasionally, a third condition may appear:
-
CLEAR OR BRIGHT YELLOW - This means the fluid level is below the bottom of the hydrometer. This may have been caused by excessive
or prolonged charging, a broken case, excessive tipping, or normal battery wear. Finding a battery in this condition may indicate high charging
by a faulty charging system. Therefore, the charging and the electrical systems may need to be checked if a cranking complaint exists. If the
cranking complaint is caused by the battery, replace the battery.
