Auto Electrical Repair - Know Thy Battery PDF Print E-mail
Friday, 27 June 2008 08:00

When doing auto electrical repair, the first vehicle component your should acquire knowledge about is the car battery. Even though the battery only store 12 volts, it is the electrical source of the entire vehicle. You will not be able to start your engine without the battery. In addition the auto battery helps to operate all the electrical accessories installed on your motorcar. An auto battery should last 3-5 years in average climates. Extreme hot or cold climates however, will reduce this to only 2-3 years.

An auto battery is built up of six cells, each containing stacked positive and negative lead plates. These are divided and separated by insulators and immersed in an electrolyte, a liquid blend of sulfuric acid and water. However, some batteries, use a gel instead of the electrolyte. This is considered to be safer and because you do not have to refill it with electrolyte, it has been labelled "maintenance-free". Each cell generates or more correctly put, stores 2.1 volts for a total of 12.6 volts.

Between the electrolyte and the lead plates, a chemical reaction is created. This produces dangerous, explosive gases that vent through the battery cover vents. Because of this, caution should be taken when you charge or jump start a low battery. The same caution should also be taken every time you are working under the hood of your vehicle. It is important to provide as good ventilation as possible in the battery, so always keep it clean. All batteries, even those using gel instead of electrolyte lose charging capacity as the time passes. The reason for this is that the chemical breakdown of the connections inevitably takes place leading to the deterioration of the plates and loss of the electrolyte. When your vehicle has start up or charging problems, the vehicle troubleshooting procedure should start with a test of the battery. You do that with a visual check followed by a voltage test. If the battery is ok, other components of the electrical system is probably the reason, but battery problems are by far the most likely reason.

A good thing with battery checking and trouble shooting is that you need very little technical equipment. All you need is a good, old Digital Volt Ohm Meter and a charger for the battery. Each auto battery manufacturer uses a certain color in the battery "eye" which tells whether a charge is needed. This is a fast and easy way to alert you for re-charging. Check out your battery manufacturer"s specification of the ‘eye’ and everything associated with it.

If you need to replace your auto battery, always test it before you replace it. Also test the entire electrical system of your car. The reason for your battery problem might be a weak alternator or a drain on the system and if this is the case it won"t take many weeks before your have to replace the new one as well. What seems to be a battery problem is not always caused by the battery itself. You can acquire more information about how to repair your car"s electrical system on the web.

It All Starts Here - A Review of the Automotive Starter Battery Market PDF Print E-mail
Sunday, 27 January 2008 14:00

Consolidation among the major battery manufacturers continues to shape the industry, particularly across Europe. Johann-Friedrich Dempwolff, Vice President Sales OEM/OES, VB Autobatterie GmbH, said: “If you look back to 1990, in Germany there were ten battery producers. In the UK there were at least five producers. In France there were several. In Italy there were over 50 very small businesses. All this has dramatically changed over the last decade. There are only a few strong players left in the marketplace.”

“The result of tighter environmental requirements, together with other legislation, has been the closure of plants in Western Europe and a move to the Far East, particularly China, and to super-plants,” said Lucas Batteries’ David Haseler. “We have recently announced the closure of our Birmingham [UK] factory for manufacturing, and will be sourcing from companies in Asia. Our advantage is that these are company-owned plants which will allow us to maintain a close control over supply and quality.”

Today, four valve regulated lead-acid battery manufacturers – of which three are American -- have emerged as global players: Johnson Controls, Delphi, Exide Technologies and Yuasa. These four companies collectively control 55% of the global market. Johnson Controls recently signaled its intention to buy Delphi’s global battery business for $212.5 million. Yuasa recently merged with Japan Storage Battery, forming GS Yuasa Corp. Yuasa holds an 8% share of the global lead storage battery market while Japan Storage Battery has a 6% share. Their combined market share of 14% ranks them in third place in the global market.

The flood of imported batteries from tiger economies (such as China, Thailand, Indonesia and Malaysia) is also posing a serious challenge to European manufacturers. That has become a double-whammy for UK-based supplies since the imported units are especially cheap due to the weak dollar. Perversely, the Asian manufacturers have driven up the cost of lead because their consumption of it is so high. The price of oil is also driving up the cost of polypropylene used in battery manufacture.

Technically speaking, the starter battery market has moved completely to calcium-calcium technology, and the change is now almost complete in the aftermarket, certainly in developed countries. Lucas Batteries’ Haseler said: “There is a fast-growing requirement for sealed [non-accessible] lids with re-condensing features in the OE market, and this changeover should be complete within a few years. This reflects the trend in the automotive industry for sealed units. This is being closely followed by the requirement for a ‘tip-tilt’ lid, that is, a lid that will not allow any acid to leak out of the battery for at least 30 minutes with the battery at any angle. If the battery is still being charged, this time reduces to two minutes. This is achieved by a more complex labyrinth within the lid. This trend originated in Germany. The aftermarket can be expected to follow within a year or so. Sealed and tip-tilt lids are a consequence of the trend for greater safety and, in particular, the need to prevent access to the acid within a battery. Following the unsuccessful launch of VRLA [valve regulated lead acid batteries] into the OE market a few years ago, a second wave is now underway in companies such as Daimler-Chrysler and Citroen with its recently-launched C3. The Citroen C3 is the first of the long-heralded stop-start cars, in which the engine stops whenever the car stops, leaving the battery to power all the electrical system. This regime will increase the cycling loads on the battery, a demand which VRLA technology is best suited to supply. The drive for fewer emissions, associated with the need for better fuel-consumption, has clearly resulted in the move to stop-start cars.”

Austria’s Banner GmbH also sees the battery business moving toward calcium-calcium technology, particularly for cars introduced from 1997 onwards. Andreas Sperl, marketing manager, Banner GmbH, said: “These vehicles typically require modern charge management, higher voltage and maintenance free batteries. Given that batteries are often situated in places where the driver cannot see it -- let alone the brand name -- the battery must be maintenance free, leak proof and spill proof.”

On the aftermarket side of the automotive starter battery business, the market is shaped by a number of factors. “The car parc is increasing,” added Dempwolffe. “Secondly, the product is improving so the life of product is longer. And the electrical systems – which in the end determines the life of the battery – if you have a good charging system in your car, then this extends the life of the battery. On the other hand, the power consumption is increasing which is minimising the battery life. But overall, we see that the battery is extending its life and the market is stable and slightly shrinking. This of course is another challenge, especially for smaller producers. We believe that there is a slight shrinkage of the market year-on-year.”

According to industry sources, an OE vehicle starter battery for a passenger car should last around six years. That’s up from three or four years in the early 1990s. The useful life of a replacement battery may be a little less, perhaps around five years. For a commercial vehicle and motorcycle, manufacturers estimate the useful life of a battery is three or four years,

“Due to Europe’s congested cities, a lot of cars are now traveling in stop and go traffic, adding wear on the battery,” added Sperl. “The sheer heat generated under the bonnet due to an overcrowded engine compartment and the fact that batteries are located close to the engine block means that batteries are just as likely to fail in the summer as in the winter. Ten years ago, we would have said our battery aftermarket business was seasonal. But now it’s an all year round business.”

The power of brands appears to be diminishing in Europe, depending on the target segment. As far as the UK is concerned, that may relate to the fact that all the major battery manufacturers no longer produce batteries in Britain, as Paul Matarewicz, Managing Director for Varta Automotive Batterie, said: “It was driven by people who actually made batteries in the UK. As they have shut down and pulled out, they have been replaced by imported products from the Far East, South Africa and Brazil. These products are coming in without a label on and therefore you get a huge number of no-name products flooding the UK market. In the early 1990s, the UK aftermarket was about 60% branded. If you go back to the early 1980s, it was more like 90% branded. So there has been a very steady decline in brand.”

Another major issue facing the industry is the escalating price of lead. Given that lead typically accounts for 40% of manufacturing costs, any severe oscillations in price can have serious consequences. But producers can’t chop and change their strategy every time the price of lead moves. While some producers use an array of measures to manage price movements such as hedging and improving their spent battery collection rates, surely the key is to negotiate with the OEMs to assist them in absorbing the lead price increases. Put simply, battery producers can’t absorb a 100% increase in price in 40% of raw material costs. Otherwise, we shall see yet more consolidation ahead.

Although lead-acid starter batteries may not appear to have changed over the last four decades, internally, technological advances have been made to ensure that they keep up with modern demands. Lead-acid batteries will continue to start cars for many years, but the search continues for lighter, more efficient and cleaner replacements.

Quick and simple instructions on using a car battery charger PDF Print E-mail
Tuesday, 08 January 2008 04:00

I am sure everyone at one time or the other has left the head lights or some other electrical device on and drained your car battery. You may not need to run out and purchase a new battery. A car battery charger can save the day. They are relatively simple to use and operate. Just follow these simple steps and soon your car will back to normal.

1) First, remove the battery cables from the terminal posts. Remember to remove the (-) negative cable first. (This cable is usually black) and then the (+) positive cable. Don’t forget that all your stereo settings will probably be lost when the power is cut off.

2) Now you are ready to hook up the car battery charger to your car. But first, read the owner’s manual and insure that the model charger you are using is suitable for your car. Now, hook the (+) positive cable (red) to the positive terminal and then the (-) negative cable (black) to the negative terminal.

3) Now plug in your car battery charger and switch it on. Al light or some other indicator should turn on. (Consult your owner’s manual)

4) Wait for another indicator to come on to show that the charge is complete. Remove the cables starting with the (-) negative cable (black) first and reconnect your battery.

If your car still fails to crank up, you may have to purchase a new battery or there may be a more serious problem.
