Car Battery Life
Battery life has been defined as the period in which it lasts for service without any damage. Battery life is reduced by overcharging which causes overheating and excessive gas bubbling.
In a car, the battery can be overcharged due to a faulty generator control which causes the generator to continue to charge the battery after it is fully charged. Too concentrated electrolyte also causes overcharging. Lack of water not only makes the electrolyte concentrated but, it reduces electrolyte levels in the cell, thus causing disintegration of the exposed plates.
If a battery is continuously undercharged, it becomes Sulphated, which causes a loss of active material. It also causes the plates to buckle and break. Excessive loads, such as those produced by propelling the car with the starting motor, are detrimental to the battery.
The battery is completely damaged if the electrolyte freezes in it. The freezing points of various solutions depending on the state of charge are given in the following table:
|Freezing point^ 0 F.
To compensate for loss, distilled water must be added to the battery to prevent the dissolved materials. In freezing weather, it should be added just before the car is avoided by having it freeze before combining with the acid.
6 Factors that Affect Your Car Battery Life
The car battery life and health depend on how we treat that battery from time to time. If a driver is aware of what to do with the battery plats and the other parts then the life of a lead-acid battery can increase in time. Here, I have discussed the 6 problems that can affect the battery life of your car. These are-
- Lack of Water.
- Loose hold-downs.
- Excessive load.
- Freezing Electrolyte.
Charging a battery greatly an excess of what is required is harmful in several ways, as follows –
1. Decompose water of electrolyte into hydrogen and oxygen gas. Gas bubbles tend to wash active materials from the plates and carry moister and acid from the cells as a fine mist.
2. Decomposition of water leaves acid more concentrated. Concentrated acid is harmful to separators and negative plate material at high temperatures over a prolonged period of time, charging the separators and making the negative material sandy and granular.
3. High internal heat is created, which accelerates the corrosion of positive plate grids and damages separators. Also, containers may be softened and distorted and the sealing compound displaced.
4. Overcharging alone or in combination with a previous condition of undercharging may cause severe buckling and wrapping of positive plates with accompanying preformation of separators.
5. May cause damage by corrosion to the cradle, cables, and other vital electrical and engine parts by forcing liquid from the cell if charging rates are excessive.
