9.2.16.1 Preparing the Battery
-
Remove the cap from the bleeder, shown in the
figure, and then carefully pour sulphuric acid into
each element.
Note: the acid must have a density of 78.7
lbs·ft
- 3
( 1,260 kg·m
- 3
), equivalent to 30 BE at a
minimum temperature of 59°F ( 15°C ) until the
upper level is reached.
-
Let the battery rest at least 2 hours, and then
restore the level by pouring additional sulphuric
acid as required.
-
Recharge the battery using the recommended
battery charger 020333Y (single) or 020334Y
(multiple) at an intensity of about 1/10 of the
battery’s nominal capacity and until the acid
density is about 79.3 lbs·ft
- 3
( 1,270 kg·m
- 3
),
corresponding to 31 BE and such values become
steady.
-
After charging, level the acid (adding distilled
water ). Close and clean carefully.
-
After performing the above operations, install
the battery on the vehicle following the steps
described in “Battery recharge” section of this
manual.
9.2.16.2 Checking the Electrolyte Level
The electrolyte level must be checked frequently and must reach the upper mark. If the
level is too low, it can be restored only by using distilled water. If water toppings are
required too often, check the vehicle electrical system as this inconvenient is usually a
symptom that the battery is working over-charged and is subject to quick wear.
9.2.16.3 Checking the Electrolyte Density
After restoring the electrolyte level, check its density by using the density gauge.
When the battery is charged, density should be equal to 30÷32 BE, corresponding to a
specific weight of 78.7-79.9 lbs·ft
- 3
( 12.4-12.6 kN·m
- 3
) at a minimum temperature of 59°F
( 15° C ).
If density is below 20 BE, the battery is fully discharged and it is therefore necessary to
recharge it.
If the vehicle is not used for a certain period (1 month or more), the battery must be
