All our products have a minimum 12 months warranty cover, All warranties are a "return to base warranty", in the unlikely event you experience a problem with your product please return it with a copy of your sales invoice to us at: Battery Specialist NW Ltd, Battery House, 244 Derby Rd, Bootle, Liverpool, L20 8LJ for testing. When returning batteries please make sure they are properly packaged in a suitable box with packing for protection while in transit, we will not be held responsible for any damaged caused to items not packed by us. If your item is found to have a manufacturing fault a replacement will be issued, if the item is no longer available a item of similar specification will be offered. Please make sure there is no drain on the battery such as interior lights and dashboard signals staying on, It is important to have your product tested before returning it to us to avoid any unnecessary charges, we 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 signifiesirreversible 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.
