Please ensure you retain your original invoice for your
records and a test report for any battery which may appear faulty. No
warranty claim can be honoured without these particulars. In
the unlikely event that you should experience problems with your
item please contact us immediately. We will organise a replacement
on confirmation of a faulty battery. Battery2u will not accept
the following as warranty claims.
Sulphation - If a battery is allowed to stand
in a discharged state for an excessive amount of time, a chemical
reaction takes place, which can permanently impair performance-
this is sulphation. Sulphation can be seen as a fine white/grey
coating on the plates. In most cases this signifies irreversible
damage and the battery will not be serviceable. This
damage can occur either in storage or if the battery is installed
in a vehicle (or equipment) that is not used for a period of
time, for example a tractor, motorcycle or boat. Even a car or
truck that is stored with the battery connected can still damage
the battery in this way. This is because there is a permanent
drain from the clock, alarm etc. As a result the level of charge
in a battery falls, and after a period of time sulphation will
build up on the plates.
The sulphation (lead sulphate) hinders the chemical reaction
between the acid (electrolyte) and the active mass (lead compound)
in the plates and prevents the battery operating as normal. This
is not a manufacturing fault.
Wear and Tear – During the charge and discharge
cycle, material from the battery plates (active mass) is in motion,
through the electrochemical reaction that produces electricity.
Every time the battery goes through a charge and discharge cycle,
a small amount of the active mass is lost from the plates. Because
the ultimate life of a battery depends on so many factors, it
is impossible to stipulate a minimum/maximum life expectancy.
This process of normal ageing through the charge and discharge
cycle will eventually cause the battery to lose capacity, and
it will come to the point where the battery can no longer start
the vehicle/equipment. This is not a manufacturing fault.
Deep Cycling – As mentioned above, every time
a battery goes through a charge and discharge cycle a small amount
of the material from the plates is lost. If a battery is subjected
to deep discharging (i.e. over 40%) and then rapid charging,
this process is accelerated. Additionally, if during the recharge
the battery is not adequately compensated for the discharge cycle,
the battery will quickly exhibit loss of performance. Even after
recharging the voltage will be low (under 12.4v) but the cells
will generally give even readings. This is not a manufacturing
fault.
Overcharging – If the regulator is not set
properly, then the battery can be subjected to an excessive charge.
If left unchecked the battery will overheat and will start to
evaporate the electrolyte. The overcharging will cause the accelerated
break up of the active mass on the plates and the battery will
lose performance. This is generally obvious from the examination
of the battery – the acid levels will be very low, and quite
often a black coating will be visible on the filler caps. This
is not a manufacturing fault.
Physical Damage – If the battery is fitted
incorrectly, if the connector leads are hammered onto the terminals,
or if the leads are not properly fastened, the battery will have
obvious damage to the casing or the terminals. This is
not a manufacturing fault.
