If you own a laptop computer, probabilities are very very good that it is in all probability powered by a lithium-ion (Li-ion) battery. This battery type has found application in a wide potpourri of buyer electronics, including PDAs and cell phones. They have gained widespread popularity due to economic and technical reasons, exceptionally their high charge to weight ratio. Lithium-ion batteries have substituted the nickel-cadmium (NiCd) batteries that were introductory used to power laptop computers and the nickel-metal hydride (NiMH) batteries that superseded the NiCd laptop battery technology. They have overshadowed today’s rechargeable battery market for laptop computers because they are much lighter than the other types of laptop batteries, they retain their charge longer than the other technologies and because they do not suffer from the memory effect phenomenon. A typical lithium-ion battery has two times the energy density of a standard nickel cadmium battery. Additionally, lithium-ion batteries have a single cell voltage of 3.6 volts as equated to 1.2 volts per cell of nickel-cadmium batteries. However, the disfavors affiliated with lithium-ion batteries include: the possibleness that a failed battery pack may ignite underneath averse conditions, they are more sensible to high temperature environments than the other battery technologies in their capacity to retain their charge, they may fail if they are wholly discharged, and the inherit alchemy of the battery leads to degradation with age as opposed to the more inviolable correlation amid battery failures and charge/discharge cycles of the older battery chemistries. Lithium-ion computer batteries also require that shelter circuitry be integrated into the battery pack to monitor the battery charge and to provide safe voltage and current levels, as well as ensuring that the temperature of the battery remains in a safe operating range. Cylindrical lithium-ion battery cells are in general tubular in shape, much like the shape of ordinary alkaline batteries. Several cells are enclosed in a plastic housing and the person cells are connected in a manner to provide the proper output voltage and to maximize storage capacity (rated in milliamp-hours). Prismatic shaped lithium-ion cells are also available, but they are much littler and are specifically used in appliances such as cell phones where weight and space is a prime consideration. There are various things that affect the life of a lithium-ion laptop battery. Battery degradation is hastened by heat, so storing the battery in a cool surroundings will prolong it is life. Manufacturers distinctively commend a storage temperature of approximately 60°F for the long-term storage of lithium-ion batteries. These batteries, as stated previously, do not retain a memory from partial discharge cycles, so full discharge cycles are not required. In fact, partial cycling of the battery will aid extend it is life. Lithium-ion batteries do have a fixed lifetime like the older battery technologies, but this is comparatively independent of their charging cycles and is chiefly affiliated to their age. A typical battery will last only 2 to 3 years. This is true even if the battery remains unused so it is indispensable not to buy a substitute laptop battery until it is ready to be put into service.
