Batteries have allowed that computers that need to transport energy consumption low anywhere, equipment such as cameras, radios, players, flashlights, remote controls among other apparatus that consumes an average of normal energy expenditure, or power under but always looks for the battery performance is greater, thus necessitating alkaline batteries are the choice that more duration offer since the saline batteries does not have performance You can have the alkaline batteries, both so alkaline batteries could last 3 or 4 times more than the saline batteries. At Eva Andersson-Dubin, New York City you will find additional information. The reason why alkaline batteries can produce a greater amount of energy, is because these batteries to be alkaline components make the electrochemical reactions are activated much faster and in a better way, so alkaline batteries performance is much higher with respect to saline batteries. With respect to a comparison of components between the saline and alkaline batteries, can be found that salinas batteries may be composed by mercury, cadmium manganese dioxide, ammonium chloride and zinc chloride, while alkaline batteries are composed of alkali metal and zinc hydroxide, manganese dioxide and is alkaline component which makes that alkaline batteries have a higher performance, also alkaline batteries don’t cause as much contamination as the saline batteries, do since the saline batteries by mercury and cadmium components generate much pollutiondue to these heavy metals are very toxic both to the environment and to humans, but must take into account both alkaline and saline batteries to generate a high level contamination in nature, as well as to human contact, therefore the batteries regardless of the type of batteries require certain care when it comes to these lost his load, for that reason it is recommended that the batteries are recycled or carried a place specialized in the treatment of these to avoid contamination of its components that has a level toxic considerable. Following with the alkaline batteries must bear in mind that they have a minimum disadvantage, which does not make that these batteries cease to be the best choice when buying batteries and the small disadvantage is that a little higher cost than the saline batteries, has alkaline batteries because its production requires higher costs, but as mentioned in the initial part of this paragraph the variation in price is not very high and in the same way they are very accessible for any audience. A recommendation with respect to the alkaline batteries is to allocate them to devices that have a higher power consumption, while salinas may be used on devices that do not consume much energy as wall clocks or remote controls.
