Fluid Quantity
The fluid level should be between the "UPPER' and "LOWER' level lines. If the
level is low, add distilled water up to the 'UPPER' line.
NOTE:
If your battery has only one level line, the line indicates the "LOWER" level
(lowest).
If your battery has no level line, the fluid level should be between 10 and
15mm above the plates.
If the level is low, add distilled water until it is 15mm above the plates.
NOTE:
After addition of water, be sure to charge the battery (by operating the vehicle),
because otherwise the fluid could be frozen in winter.
Specific gravity
Measure the specific gravity. If it is less than 1.220 (at a fluid temperature of
20~C), recharge the battery.
NOTE:
The standard specific gravity of battery is 1.260 to 1.270 (at a fluid temperature
of 20~C).
