The function of a car battery

The battery in a car provides power during ignition and energy for the various electrical systems. There are a number of different types of car batteries in Dearborn that are in common use, one of which is a “flooded” battery.

A flooded battery is one which consists of a number of lead plates which are suspended in a bath of sulphuric acid, the plates and the acid are contained within a case usually made from polyurethane. This type of battery construction requires maintenance. Water in this type of battery is lost as hydrogen and oxygen gas, to maintain the electrolysis process it is necessary to top up the level periodically with distilled water, it is important that the tops of the plates are not exposed, the plates must always be in the electrolyte.

Although a flooded battery that requires maintenance is still in use, many vehicle owners as well as vehicle manufacturers have switched to a maintenance free sealed unit. This type of battery is more or less the same as a flooded battery other than the fact it is sealed so no water can be lost.

How do batteries work?

All batteries in Dearborn are devices that store power for use in the future. Voltage is produced from a chemical reaction between unlike materials such as the positive and negative plates which are immersed in a mixture of water and sulphuric acid. In a typical car battery the voltage is about 2 per cell, as there are six cells the battery is rated 12 volt. The moment there is a circuit between the poles, electricity flows out of the battery. The voltage is used to start the engine or run an accessory such as a radio.

Car batteries are constantly charging and discharging. When you are starting the engine current flows out of the battery; as you drive and there are no accessories drawing current, the alternator charges the battery, current flows into the battery.

As the battery ages the plates begin to be more chemically alike, the strength of the acid weakens and the voltage drops. Eventually the battery becomes completely discharged, when this happens it cannot produce useful voltage.

The term “dead battery” is not always correct. If the battery in your car is simply discharged because the lights were left on for example, the battery can be charged to full capacity. When batteries in Dearborn have reached the end of their useful life it is not possible to recharge them enough to be of any use, a new battery must be purchased and installed.
