A lead-acid battery (also know as an "accumulator") is a secondary (rechargeable) electrochemical device that stores chemical energy and releases it as electrical energy upon demand. To provide extra power for the lighting, two-way radios, audio system and other accessories when their combined load exceeds the capability of the vehicle's charging system. To supply a source of power to the vehicle's electrical system when the charging system is not operating. A good quality wet car battery will cost between $90 and $125 and, if properly maintained, should last five years or more.
Forbes reported that Johnson Controls is the largest global manufacturer with 36% of the approximately 375 million annually produced. The purpose of a deep cycle battery is to provide electric power for wheelchairs, trolling motors, golf carts, boats, fork lift trucks, uninterruptible power supplies (UPS), and other accessories for marine and recreational vehicle (RV), commercial and stationary applications. A 12-volt lead-acid battery is made up of six cells, each cell producing approximately 2.11 volts that are connected in series from POSITIVE (+) terminal of the first cell to the NEGATIVE (-) terminal of the second cell and so on.
The most common plate type in use today is made up of a metal grid that serves as the supporting framework for the active porous material that is "pasted" on it.
A battery is created by electrochemical reaction of alternating two different metals such as Lead Dioxide (PbO2), the positive plates, and Sponge lead (Pb), the negative plates immersed in diluted Sulfuric Acid (H2SO4), electrolyte. When the active material in the plates can no longer sustain a discharge current, a battery "dies". Normally, well maintained and properly charged deep cycle batteries naturally die due to positive grid corrosion causing an open connection. In a hot climate, the harshest environment for a battery, a Johnson Controls survey of junk batteries revealed that the average life of a car battery was 37 months.
Most of the "defective" batteries returned to manufacturers during free replacement warranty periods are good. The vast majority of car batteries are part of the lead-acid battery group, where they fall into the SLI category. SLI batteries constitute six galvanic cells – see the ‘Anatomy of a car battery’ diagram for details – laid out in series. Each galvanic cell consists of a series of lead and lead dioxide plates which are submerged in an electrolyte solution – a mix of sulphuric acid (35 per cent) and water (65 per cent).
The reaction is not permanent, with the lead sulphate reforming into lead dioxide and lead when the battery is recharged.
Watch as a train pile-drives into a crash-proof nuclear container to test its impact threshold in a 100 MPH head-on collision. That’s why we always do an alternator test to be sure that the alternator is putting out enough power to keep your battery charged. Your battery provides required power to maintain the operation of accessories when the car engine is turned off. The battery also supplements the power from the charging system during periods of high demand – like when you’re stuck in traffic with your headlights, wipers and blower motor all running! The voltage regulator controls the voltage, keeping it within the proper operating range of your car’s entire electrical system. The starting system on your car includes the ignition switch, the starter relay or solenoid and the starter motor. Any actual physical damage to the body of the battery means that you should replace the entire unit at your earliest possible opportunity. In order to make sure your battery is in good condition you should check the top of your battery for dirt and electrolyte.

Whichever method you use, the type of battery that you’ll need is going to depend on your car’s make and model.
If you don’t want to worry about picking out the wrong battery, you could go online and find a website that provides car battery information for each car’s make and model, or you could go to the auto store and let them install a new car battery. Everybody loves their cars, and most people just want their cars to be well looked after and loved.
So, if you’re vacationing in New York and looking for car rental deals, you need look no further than Brooklyn. When a battery is connected to a resistive load, such as a motor, chemical energy is converted to electrical energy and direct current flows through the circuit. This commonly occurs while the vehicle's engine is idling or during short trips with a heavy power load like at night in bad weather. A good quality wet deep cycle (or "leisure") battery will cost between $50 and $300 and, if properly maintained and used, will give you at least 200 deep discharge-charge cycles. Each cell is made up of an element containing positive plates that are all connected together and negative plates, which are also all connected together. After the "curing" of the plates, they are made up into cells, and the cells are inserted into a high-density tough polypropylene or hard rubber case.


Porosity is the pits and tunnels in the plate that allows the sulphuric acid to get to the interior of the plate. Normally a car (or starting) battery "ages" as sulfation builds up on the negative plates or the active positive plate material sheds (or flakes off) due to the normal expansion and contraction that occurs during the discharge and charge cycles.
This strongly suggests that some sellers of new batteries do not know how to or fail to take the time to properly recharge and test batteries.
SLI stands for ‘starting – lightingignition’ – a reference to what the device is responsible for within a vehicle; in other words, it not only powers the car’s starter motor but the ignition and lighting systems too.
This acidic bath triggers a reaction with the lead dioxide plate (the positive electrode) which produces ions and lead sulphate. Over time, the battery’s efficiency will deplete, with most working optimally for about four years. If you constantly need to jump-start your car, especially when it’s cold, you probably need your car battery replaced. These three components of the starting system consume more electrical power than any other system on your car.
CCA or Cold Cranking Amps is a measurement to assure that your car battery had sufficient energy to crank the engine over when it’s cold. Whilst a failing battery will not generally result in your car breaking down on the road, it will prevent your vehicle from being started. Damaged batteries can leak in the engine and corrode other parts, so any sign that the battery’s casing is not in good condition should be taken seriously. Too much electrolyte on the top of the battery is usually caused by overfilling and is not a cause for concern – rather a sign that you should be more careful next time you fill your battery. As these batteries use a mix of water and acid in the cells to form the electrolyte the water can evaporate during the summer months. Usually you will only have to add distilled water to the battery and if you see that a cell has run completely dry then you should check the battery to make sure there are no cracks in the casing. People travel from all around Sydney to our shop in Rozelle to get the best price on their car battery needs. The car battery is needed to power the starter motor, the lights, and the ignition system of a vehicle.
You should be able to find the battery group size in the manual as well as the rest of the information that you are going to need.
This lets us know the amount of amps the battery can put out before needing to be recharged. Go to the auto store or the automotive section of a store like Wal-Mart and pick out a battery that meets all of the above specifications of your car battery.
After having a professional put the right one in, you won’t have to ask, what battery fits my car? Approximately 850 to 900 million lead-acid batteries are in use worldwide with starting batteries representing approximately 88% of the total. With an estimated 3% compounded annual growth rate, worldwide retail sales of car lead-acid batteries represent roughly 63% of the estimated $30 billion annually spent on batteries. In another marketing study by Recharge, in 2003 the worldwide battery market was roughly $30 billion, with 30% of that being SLI (car) and 15.3% industrial (deep cycle) lead-acid batteries. They are individually separated with thin sheets of electrically insulating, porous material "envelopes" or "separators" (in the diagram below) that are used as spacers between the positive (usually light orange) and negative (usually slate gray) plates to keep them from electrically shorting to each other. The positive plates in cells are connected in parallel to the external POSITIVE (+) terminal and the negative plates in each cell are connected to the NEGATIVE (-) external terminal. If deep cycle battery is left discharged for long period of time, dendrite shorts between the plates can occur when the battery is recharged. This situation is improving with the widespread use of easy to use battery testers like those made by Cadex, Midtronics and Solar.
One of these 12-volt batteries is powerful enough to keep a car’s systems running for years, though larger diesel vehicles may employ two.
These sulphuric ions then react with the adjacent lead plates (the negative electrode) to produce hydrogen ions and lead sulphate. Did you know that a bad alternator that’s not properly charging your car battery could cause this problem? Drawing on your car battery, the starter motor turns the engine over or cranks it until your car starts. We’d always advise that you do a quick visual inspection of your battery any time you open the bonnet of your car to check the oil, top up brake fluid or refill the car’s water tank. Equally you should replace frayed, worn or broken cables as soon as possible as these are a vital part of the engine’s starting system, carrying the charge that’s used to start the combustion process.
However, you will need to remove any dirt from the top of the battery as this can form an electrical bridge that can cause the battery to discharge when the vehicle is at a standstill. Also never add acid to a cell that already contains electrolyte – this can damage the electrical balance of the battery and cause failure. If you’ve lost your owner’s manual, you can also remove the battery and check the label for the majority of this information.


This lets you know how many amps can be accessed during a 30 second period of time before the battery fails. In North America, BCI reports that approximately 120 million car and motorcycle batteries were sold in 2010, of which approximately 88% were for replacement and 12% were for original equipment.
In the June 2015 report, Environmental Protection Acency stated that approximately 99% of all lead-acid car batteries were recycled in the U.S.
Purportedly, Exide and EnerSys are the two largest deep cycle battery manufacturers in the world. The plates (in the diagram below), within a cell, alternate with a positive plate, a negative plate and so on. When you are using your battery, the fresh acid needs to be in contact with the plate material and the water generated needs to be carried away from the plate.
The chemical action between the metals and the electrolyte (battery acid) creates the electrical energy. A brown sediment, called sludge or "mud," that builds up in the bottom of the case and can short the plates of a cell out.
The low resistance bridge in the shorted cell will heat up and boil the electrolyte out of the cell causing a high volumes of hydrogen and oxygen. If your car battery is more than three years old and you live in a hot climate, then your battery is probably living on borrowed time. This chemical reaction, in turn, generates electrons that can flow out via conductive terminals as electricity to power essential functions.
This way you should be able to anticipate any problems with the battery before they happen, preventing that awkward moment in the morning where your car won’t start.
Finally take a look at the fixings for the battery – any looseness could allow the battery to vibrate and the connections could be dislodged.
Use a screwdriver to pull of the cell cover to inspect the electrolyte levels – this should be well above the plates. For 2003, Eurobat estimates that in Western Europe 58.5 million car batteries will be sold and 71% will be replacement (after market) and 29% will be OEM (Original Equipment Manufacturer).
Energy flows from the battery as soon as there is an electrical load, for example, a starter motor, that completes a circuit between the positive terminal connected to the positive plates and the negative terminal connected to the negative plates. Abnormally slow cranking, especially on a cold day, is another good indication that your battery is going bad. The battery is initially charged or "formed" to convert the active yellow Lead Oxide (PbO or Litharge) in the positive plates (cathode) into Lead Peroxide (PbO2), which is usually dark brown or black. Electrical current flows as charged portions of acid (ions) between the battery plates and as electrons through the external circuit. In hot climates, additional causes of failure are positive grid growth, positive grid metal corrosion, Dendrite formation, negative grid shrinkage, buckling of plates, or loss of water. Approximately 85% of premature deep cycle and starting batteries failures that are not recharged on a regular basis is due to an accumulation of sulfation. If the fluid does not reach this level then you should add distilled water – not tap water due to impurities within the liquid – to bring it up to the normal required level.
The active material in the negative pasted plates (anode) becomes sponge Lead (Pb), but with a very porous structure which is slate gray. The action of the lead-acid storage battery is determined by chemicals used, State-of-Charge, temperature, porosity, diffusion, and load. Deep discharges, heat, vibration, fast charging, and overcharging all accelerate the "aging" process.
Sulfation is caused when a battery's State-of-Charge drops below 100% for long periods or under charging. When you add the water only use a plastic container or funnel as a metal one could touch the plates and cause the battery to discharge rapidly, which could injure you. Approximately 50% of premature car battery failures is caused by the loss of water for normal recharging charging due to the lack of maintenance, evaporation from high under hood heat, or overcharging. You can easily spend the cost of a new battery or more for an emergency jump start, tow or taxi ride.
Antimony (Sb), Calcium (Ca) or other alloys are often added to the plates to enhance their performance or service life.
Positive grid growth and undercharging causing sulfation and electrical system malfunctions also cause premature battery failures.
A "Wet charged" battery is a wet lead-acid battery shipped with electrolyte in the battery and a "dry charged" battery is shipped without electrolyte.
