Camcorder Battery
October 15, 2008People have always enjoyed taking photos. This first started with the ordinary camera. With the changing times, the camcorder is the most used for taking pictures that we cherish and keep. The digital camera or the camcorder as it is known, can take picture for hours without letting us miss any of the important events in a function. It can take still photos, audio and video images. All this needs enough power. This is provided by the powerful batteries that are used. A person can also carry these batteries which can be replaced if the first set of batteries runs out. This is possible because the batteries are light weight.
The advantages of these batteries are that it can take pictures for about eight to nine hours at a length. Today, the camcorder uses lithium batteries which are easily available. These lithium batteries increase the activeness of the camcorder.
The pictures taken nowadays are better than the earlier ones. This difference is due to the type of batteries used. The earlier models were heavy due to the size of the batteries and could not take pictures for a long time. This was because the batteries used were the Nickel Cadmium (NiCd) or the Nickel Metal Hydride (NiMH) batteries. With the advent of the Lithium ion (L-ion) batteries the camcorder has become more efficient.
The lithium ion batteries have made the camcorder lighter. The batteries are less bulky than the nickel Cadmium and Nickel Metal Hydride batteries. Their size is smaller and they also weigh less. Lithium batteries also give three times the voltage of the former two types of batteries. These batteries can be partially charged. They are not troubled by the ‘memory effect’. This means that the batteries do not have to be continually completely discharged fully and then charged again, because of which the charging capacity used to be reduced. The lithium batteries do not require ‘memory’ and scheduled ‘cycles’ of charging to prolong their life. This advantage leads to low maintenance.
The camcorder is portable. The lithium ion batteries used in this are cobalt based. It consists of a cobalt oxide positive electrode (cathode) and a graphite carbon in the negative electrode (anode). This results in a long run time due to its high energy density. The lithium batteries have to be charged only according to the manufacturer’s instructions. There is no other way to do it.
In the earlier models of batteries, some batteries may have a long run time but limited run cycles, another set of batteries may be durable but heavy, but the latest models are durable, having a high energy density, are lightweight, but are too expensive. The person in charge of selling the batteries will be able to give us the advantages of all these various types and give us the best for our camcorder.
