Recombination Batteries

FIGURE. The recombination battery is one of the most recent advances in the automotive battery. A recent variation of the automobile battery is the recombination battery. The recombination battery is sometimes called a gel-cell battery. It does not use a liquid electrolyte. Instead, it uses separators that hold a gel-type material. The separators are placed

Hybrid Batteries

Note: The following discussion on hybrid batteries refers to a battery type and not to the batteries that are used in hybrid electric vehicles (HEVs). The hybrid battery combines the advantages of the low-maintenance and maintenance-free battery. The hybrid battery can withstand six deep cycles and still retain 100% of its original reserve capacity. The

Maintenance-Free Batteries

FIGURE. Maintenance-free batteries. In a maintenance-free battery there is no provision for the addition of water to the cells. The battery is sealed. It contains cell plates made of a slightly different compound than what is in a conventional battery. The plate grids contain calcium, cadmium, or strontium to reduce gassing and self-discharge. Gassing is

Chemical Action inside of the Battery

Activation of the battery is through the addition of electrolyte. This solution causes the chemical actions to take place between the lead peroxide of the positive plates and the sponge lead of the negative plates. The electrolyte is also the carrier that moves electric current between the positive and negative plates through the separators. The

Conventional Batteries

The conventional battery is constructed of seven basic components: Positive plates. Negative plates. Separators. Case. Plate straps. Electrolyte. Terminals. The difference between “3-year” and “5-year” batteries is the quantity of material expanders used in the construction of the plates and the number of plates used to build a cell. Material expanders are fillers that can

Automotive Batteries

An automotive battery is an electrochemical device capable of storing and producing electrical energy. Electrochemical refers to the chemical reaction of two dissimilar materials in a chemical solution that results in electrical current. When the battery is connected to an external load, such as a starter motor, an energy conversion occurs that results in an
