DC BATTERIES TERMS AND CONDITIONS OF SALE
DC BATTERIES will always supply you with the correct battery for your vehicle and follow your vehicles manufacturers fitting instructions and check that the battery is installed correctly and perform a charging system test that will highlight any underlying faults.
Battery problems ?
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 known as sulphation and is visible as a fine white/grey coating on the plates inside the battery. In most cases this signifies irreversible damage and the battery will not be serviceable. This is not a manufacturing fault. Typically the voltage will be below 12.00 volts and the acid density will 12.0 or lower, 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, typically a boat, motorcycle, or even a car or truck that is stored for for periods with the battery still connected can also cause sulphation of the battery.
DC Batteries always advise that a maintenance charger is used on batteries that are not in constant use, these keep the battery fully charged and avoids the problem of sulphation.
Deep Cycling/Wear and Tear
During the charge and discharge cycle, material from the battery plates is in motion, through the electrochemical reaction that produces electricity.
Every time a charge or discharge takes place a small amount of material is lost from the plates inside the battery, if the battery is continually subjected to deep discharging and then rapid charging, this process is accelerated, leading to a loss of battery voltage and capacity.
If the discharge is too deep i.e. 40% discharge or if the recharge function does not adequately compensate for the discharge cycle, the battery will quickly exhibit loss of performance. Even after recharging the voltage will be low (under 12.4 volts) but the cells will generally give even readings. Under a discharge test, one or more of the cells will boil but this is not a manufacturing fault.
The battery is deep cycled.
Equally a battery that has been correctly subjected to a number of charge/discharge cycles will eventually lose capacity, this is due to the general shedding of the plates in the battery and this is not a manufacturing fault, for a guide batteries on taxi’s can after 12/24 months display the above symptoms, such failures are not covered as manufacturing defects. Even in normal use with no special demands put upon it a battery will gradually lose performance because the ultimate life of the battery depends on so many factors, it is impossible to stipulate a minimum/maximum life expectancy. However, it is vital that normal ageing and wear and tear is clearly identified.
What Does The Battery Warranty Cover?
Typical manufacturing faults
Due to the high demands of the OEM market, and taking into account the technical/manufacturing standards, the rate of genuine manufacturing faults is negligible. However when faults appear, they are generally easy to spot.
Short Circuit/Dead Cell
Typically seen in a battery with a short (less than 6 months) service life, one cell will show a dramatically lower specific gravity than the others. The affected cell will boil visibly under a high rate discharge test. May also be visible as a sulphated cell, but the remaining cells will have a good S.G rating of 1.26 or over.
Internal Break
The battery will have good specific gravity readings but will show no voltage.
Warranty Summary
Provided the right battery, in the right condition, is used for the right application, the number of genuine battery problems encountered will be minimal. All batteries have a finite life span which is governed by the conditions under which the battery operates. Battery failures caused by Sulphation, Deep Cycling or Cycling out are not manufacturing faults and are not covered by the guarantee, if in any doubt please cont us.
ALL WARRANTIES ARE MANUFACTURERES WARRANTIES AND THE FINAL WARRANTY DECISION LIES WITH THE MANUFACTURER NOT DC BATTERIES, WE USUALLY DEAL WITH THE WARRANTY ON BEHALF OF THE MANUFACTURER, BUT THE MANUFACTURER DOES HAVE THE RIGHT TO CALL THE BATTERY IN FOR FURTHER TESTING.
