Electronic Control Units - Alfa Romeo 156 GTA Owner's Manual

The total absorption of these accessories
(standard and installed later) must be less
than 0.6 mA x Ah (of the battery), as shown
in the table below:
Battery Maximum permissible
loadless absorption
60 Ah
70 Ah
You are also reminded that services with
high current absorption activated by the user,
such as bottle warmers, vacuum cleaners,
cellular telephone, mini refrigerator, etc. ac-
celerate the battery drainage process if they
are powered with the engine not run-
ning or running at idle speed.
IMPORTANT It should also be noted
that improper branches on connectors of the
electric wiring for installing additional equip-
