The condition of battery cables and terminal connections can influence the reading on the hand held tester.

If you are collecting instore from our Swindon branch we can dispose of the old battery free of charge. Undercharging occurs if the battery is not receiving enough charge to return it to a full state of charge, this will slowly cause sulphation. This fault can occur if the car is being used only occasionally for short journeys, or for Start-Stop urban motoring. Undercharging will occur if alternator voltage is low (13.6-13.8volts), the alternator belt is loose or battery cables are worn and causing high resistance – If in doubt seek advice from an auto electrician. Battery Problems Manufacturing Faults The majority of commercial chargers, particularly home-chargers, are of this type, and allow neither the voltage nor the current to be preset. Use the same procedure as for Constant Potential Chargers in the paragraph above. Boost ChargersThese provide a very high initial current, and are used mainly to put some charge into a flat battery when it is needed urgently by the customer. The current falls as the battery state-of-charge increases, and the battery temperature is monitored to make sure it does not overheat. For example, if the battery has a voltage of 12.16V, charge it for 10 hours at the recommended charge rate.

The batteries recommended within this Yuasa application list are equal to or above the original equipment specification. Fitting a smaller or less powerful battery will result in a shorter service life and earlier failure. The failure will normally be seen as deep cycling/premature wear and tear. Nevertheless, it should be clearly understood that wet (filled) lead acid battery is “a live” product. Whether it is in storage or in service, it has a finite life. All batteries once filled will slowly self discharge. The higher the storage temperature and humidity of the storage area, the greater the rate of self discharge. If the battery is stored, handled or fitted incorrectly, if the connectors leads are hammered onto terminals, leads are not correctly fastened, the battery will have damage to casing and/or terminals. This is not a manufacturing fault. B. Never boost-charge any battery that is below 11.00 Volts as it will be too sulphated to accept a charge; scrap the battery or charge normally.As above, every time a battery is charge and discharge cycled a small amount of material is lost. If a battery is subjected to deep discharging (greater than 35%) and rapid charging the process is accelerated. Additionally if the recharge does not recover the discharge cycle in full, the battery will exhibit loss of performance and concentration of the acid can occur between plates which can lead to corrosion and loss of performance.

Yuasa Silver car batteries allow around 50,000 engine starts, compared to around 20,000 on a normal battery. This Yuasa YBX5110 12v 85Ah Silver High Performance SMF Battery features specialist internal components, unique design features and cutting edge technologies to combat the causes of battery failure and deliver reliability, long life and superior performance. B. These chargers should be able to charge over discharged (below 11.00V) batteries. Note that some have a special setting for all-calcium batteries. Constant Current Chargers This battery is ideal for drivers using one or more plug-in devices, such as phones, cool boxes, DVD players, and Sat Navs, and for drivers using air conditioning. Due to their increased starting capacity (CCA), these batteries are best for cold mornings. Features & Benefits: Yuasa lead-acid batteries are built to the highest standards. They are manufactured, in most cases to correspond with or exceed the vehicle manufacturer’s requirements and specifications.They provide dependable starting power, exceptional corrosion resistance and the performance to handle the demands of today’s modern vehicles. Excessive use of electrical consumers, – air conditioning, stereo (incorrectly fitted direct to the battery) etc Three times greater cycle resistance than standard batteries: highest E4 classification pursuant to EN 50342-1.

The Yuasa HSB110 Silver 12V Car Battery 5 Year Guarantee allows around 50,000 engine starts as compared to around 20,000 on a normal battery. The Silver car batteries come fully charged, ready to fit, and are completely maintenance-free. There are many types of charger available; their working principles and the procedure for using these is given below. Smart Chargers A. Boost charging is not recommended except in exceptional circumstances e.g. a stranded customer, as this will reduce battery life, especially if a battery is boost-charged more than once.

It should be noted that a vehicle fitted originally by manufacturer with an AGM battery should be replaced only with an AGM battery. Likewise, a vehicle originally fitted with an EFB battery should only be replaced by and EFB or AGM battery. Stop charging if the battery begins to gas freely (some gassing is normal during the last stages of charging) or if the battery temperature rises above 50°C. If a battery is allowed to stand in a discharged state either on or off a vehicle for a period of time, a chemical reaction takes place which will permanently impair the performance and life of the battery, this process is called “sulphation”. Terminal Layout: Negative (-) on left, Positive (+) on right ; with the terminals on the edge of the battery closest to you B. Stop charging when the battery is gassing freely and the battery-voltage shows no increase over a period of at least 2 hours.
