Liberty 125 - 200 4tempi

Commissioning dry-charged batteries :

1) - Remove the short closed tube and the caps,
then pour sulphuric acid into the cells using the
type specified for batteries with a specific gravity
of 1.26, corresponding to 30 Be at a minimum tem-
perature of 15°C until the upper level is reached.
2) - Leave to rest for at least 2 hours; then, restore
the level with sulphuric acid.
3) - Within the following 24 hours, recharge using
the specific battery charger (single) or (multiple) at
a density of about 1/10 of the battery nominal ca-
pacity until fully charged; check that the acid den-
sity is about 27, corresponding to 31 Be, and that
these values are stabilised.
4) - Once the charge is over, level the acid (by
adding distilled water). Close and clean carefully.
5) Once the above operations have been per-
formed, install the battery on the vehicle ensuring
that it is wired up properly.
1 Hold the vertical tube
2 Look at the level
3 The float must be freed
WARNING
- ONCE THE BATTERY HAS BEEN INSTALLED IN THE VE-
HICLE IT IS NECESSARY TO REPLACE THE SHORT TUBE
(WITH CLOSED END) NEAR THE + POSITIVE TERMINAL
WITH THE CORRESPONDING LONG TUBE (WITH OPEN
END), THAT YOU FIND FITTED TO THE VEHICLE, TO EN-
SURE THAT THE GASES THAT FORM CAN ESCAPE
PROPERLY.

Battery maintenance

The battery is an electrical device which requires careful monitoring and careful maintenance. The
maintenance rules are:

1) Electrolyte level check

The electrolyte level must be checked frequently and must reach the upper level. Only use distilled
water, to restore this level. If it is necessary to add water too frequently, check the vehicle electrical
system: the battery works overcharged and is subject to quick wear.

2)Load status check
