A battery is a device that stores
chemical energy and converts the chemical energy into electricity. The amount
of the electrical energy that a battery can supply, i.e. its capacity, depends
mainly on its size, and is measured in Amps per hour (A/h).
rate at which a battery converts chemical energy into electrical energy varies
according to temperature: the colder the battery, the lower the rate.
different kinds of batteries are fitted, depending on the series:
Lead-Calcium batteries have better characteristics in terms of low electrolyte
usage and less topping up of water required: they're also referred to as low
important not to forget that some machines are seasonal machines, and that
there is always a key-off power drained by the radio memory and either the
transmission or the EDC module.
battery that has been allowed to become completely discharged is hard to
recover, but the situation is much worse for Lead-Calcium batteries. If a
Lead-Calcium battery is flat, it is hard to recover it with the vehicle
charging system or with a standard battery charger: a different type of
charging cycle must be used, due to the chemical characteristics of the
battery. A computer-controlled charger must be used for this purpose, whose
cost is at present extremely high.
battery has a CCA (cold cranking amperage) capacity, which is the amount of
current the battery can provide to the starter motor at -30¡C. The CCA rating
has to be specified by every supplier.
