Golf GL L4-2.0L (AVH) (2002)
-
Dip end of hydrometer into cell and extract sufficient electrolyte to allow indicator float to swim freely (the greater the electrolyte density in
kg/cubic dm, the higher the indicator float position). Note each cell's specific gravity reading from float -arrow-. Repeat sequence until all cells are
checked.

Review noted values and compare with values in table below:
Charge condition
Specific gravity
(normal climate)
in kg/cubic dm
Discharged
1.15
Half charged
1.22
Fully charged
1.28
Example 2:
1.26 1.26 1.25 1.14 1.18 1.24
Example 1: Specific gravity in cell 4 (1.10) is too low.
Example 2: Specific gravity in cells 4 (1.10) and 5 (1.18) are too low and variation between cells exceeds 0.04 kg/cubic dm.
If specific gravity specifications are not met, replace battery.
If specific gravity specifications are met, reinstall cell caps.
CAUTION!
Only the use of genuine VW battery cell caps ensures the different battery cover systems are sealed correctly. Only use genuine cell caps of the
same construction if lost or damaged. All cell caps must be equipped with an O-ring seal.
