+ BATTERY CHARGING
All batteries charged will only be kept for seven (7) days. After fourteen (14) days all batteries not collected will be send back for recycling. It is your own responsibility to collect your battery in time. No exceptions made.
+ TERMINAL REPAIR
All repairs are done at the battery owners’ risk. Batteries are highly explosive when exposed to an open flame. We do not accept responsibility for batteries exploding during the repair process.
+ INSTALLATION AND TESTING
All installations and testing of batteries are done at the vehicle owners’ risk and are free of charge. We do not accept responsibility for any damage to a vehicle, either electrical, electronic or mechanical during the installation process. Although all precautions are taken there is always risk involved.
+ BATTERY TYPES
DEFINITIONS OF BATTERY TYPES
There is often confusion when battery deﬁnitions are used to explain various aspects of the lead acid battery eg. sealed, maintenance free and other descriptive terms. The explanation of terms below is based on deﬁnitions contained in the IEC (60095-1 :20U6) speciﬁcation for lead acid starter batteries and is meant to provide clarity in terms of the various terms used to describe batteries.
Deﬁnition for vented (ﬂooded) battery
This is the most common of automotive battery types. This type of battery has a cover with one or more openings through which gas generated by the battery may escape. A battery may also be fitted with tamper—proof plugs to prevent internal access to the battery but will still have an arrangement to allow gas generated by the battery to escape. The battery has “free” electrolyte which means that the acid moves freely within the battery.
Valve regulated (with gas recombination) battery
A secondary battery that is closed under normal conditions and has an arrangement that allows the escape of gas if the internal pressure exceeds a predetermined value. The battery cannot normally receive an addition of water or electrolyte. In this type of battery, the electrolyte is immobilised. This means that the acid is held in either a gel or a glass mat structure.
The valve regulated battery is often called a sealed battery because no addition of electrolyte or water is possible. However, the battery will have a pressure release vent to allow for the escape of gas generated by the battery.
Low water loss
Vented starter batteries may be designated as “low water loss” according to the IEC specification if the water loss of the battery is less than 4 grams per amp hour.
Very low water loss
Vented starter batteries may be designated as “very low water loss” acoording to the IEC specification if the water loss of the battery is less than one gram per amp hour.
Some specifications use the term “maintenance free” to describe a battery that has a water loss below a certain level. The IEC specification does not use this term, but rather uses the terms low and very low water loss.
+ BATTERY CARE AND MAINTENANCE
For a battery to remain in good working order, it should be maintained in a fully charged state by the vehicle’s charging system. Where a battery is used as a means of alternative power, it is generally charged by means of an independent charger or rectiﬁer which supplies controlled direct current (DC).
An independent charger is also used to charge motor vehicle batteries that have become discharged due to faulty alternators, charging systems or if left unused for prolonged periods.
If the following hints are adhered to, a battery will provide extended and trouble free service.
+ BATTERY REMOVAL AND INSTALLATION
The following procedures can be used for the removal and ﬁtment of an automotive battery:
Before removing the old battery, take note which terminal Pos+ or Neg — is connected to the ground cable. The grounded cable is usually connected to the engine or chassis.
Battery Service and Maintenance:
Inspect the battery tray, hold—downs and clamps. Replace any items damaged by excessive corrosion.
VERY IMPORTANT STEP
+ SAFETY TIPS
Safety Tips Sulphuric Acid
Sulphuric acid is contained in batteries.
Battery acid is a poisonous and corrosive liquid, which will cause burns and irritation to the skin and eyes. Take precautions when charging as sulphuric acid is given off in a ﬁne mist.
Electrical energy can be supplied from batteries and charging equipment.
Burns may occur from the heating effect of tools and conductive objects in contact with live battery terminals or conductors. In addition, sparks and molten metal may be ejected and combustible materials, notably the gaseous fumes, ignited to cause potentially lethal explosions.
It is possible to receive a severe electric shock from charging equipment and from a number of batteries connected in series i.e. five or more 12 volt batteries (+60 volt nominal).
Emergency Procedure for Treating Electric Shocks
Emission of Gasses
Hydrogen and oxygen are emitted during charging and are emitted during cranking or movement of the battery.
An explosive atmosphere is created if the concentration of hydrogen in air exceeds 4%.
Potentially a noxious product that contains substances that can harm the environment, Willard Batteries sees it as its responsibility to recycle scrap batteries. The life cycle of a lead-acid battery follows a continuous, closed loop. When a scrap battery is collected and returned to Willard Batteries, its lead and plastic are reclaimed and directed to new battery manufacturing.
