I'm assuming you're referring to Lithium-Ion batteries. The immediate advantage to Lithium battery chemistry is higher charge density. Li ions are small and mobile, but more readily stored than hydrogen. Thus a battery based on Li is smaller than one with hydrogen, such as a NiMH or NiCd, and with fewer volatile gases. Because the ions need fewer storage intermediaries, more battery weight is usable as charge, instead of overhead. Thus, Li batteries are lighter than equivalents in other chemistries - often much lighter.\n\nThe Li-ion battery does not lose quality when recharging during laptop use; it is capable of easily regulating back and forth movement of energy from powercell to powercell.\n\nA unique drawback of the Li-ion battery is that its life cycle is dependent upon aging from time of manufacturing (shelf life) regardless of whether it was charged, and not on the number of charge/discharge cycles. This drawback is not widely publicized.\n\nAs a newer chemistry, with more advanced applications, Li batteries command a higher price.\n\nThe Li-ion battery required nearly 20 years of development before it was safe enough to be used on a mass market level. While Li-ion batteries do not suffer from the memory effect, they are not as durable as NiMH or NiCd designs and can be extremely dangerous if mistreated. At a 100% charge level, a typical Li-ion laptop battery that's full most of the time at 25 degrees Celsius, will irreversibly lose approximately 20% capacity per year. This capacity loss begins from the time it was manufactured, and occurs even when the battery is unused. Different storage temperatures produce different loss results: 6% loss at 0 °C, 20% at 25 °C, and 35% at 40 °C. When stored at 40% charge level, these figures are reduced to 2%, 4%, 15% at 0, 25 and 40 degrees Celsius respectively. Every deep discharge cycle decreases its capacity, and the degradation is sloped such that 100 cycles leave the battery with about 75% to 85% of the original. When used in laptop computers or cellular phones, this rate of deterioration means that after three to five years the battery will have capacities that are too low to be usable.\n\nOne great advantage of Li-ion batteries is their low self-discharge rate of only approximately 5% per month, compared with over 30% per month and 20% per month in nickel metal hydride batteries and nickel cadmium batteries, respectively.\n\nAnother great advantage is the fact that, unlike other types of rechargeable batteries, the lifespan of a Li-ion battery remains relatively unaffected if they remain "plugged in" after they have been fully charged.\n\nUnlike NiCad batteries or NiMH batteries, lithium-ion batteries should be charged early and often. However, if they are not used for a longer time, they should be brought to a charge level of around 40%. Never use the battery care functions some cellular phones provide for nickel based batteries. (This will deep cycle the batteries.) \n\nLi-ion batteries should be kept cool. Ideally they are stored in a refrigerator. Aging will take its toll much faster at high temperatures. Keeping them in very hot cars can kill lithium-ion batteries. \n\nStoring a Li-ion battery at the correct temperature and charge makes all the difference in maintaining its storage capacity. Note that it is very important not to store your battery at full charge. A Li-ion battery stored at 40% charge will last many times longer than one stored at 100% charge, particularly at higher temperatures.\n\nIf a Li-ion battery is stored with too low a charge, you run the risk of allowing the charge to drop below the battery's low-voltage threshold, and ending up with an unrecoverably dead battery. Once the charge has dropped to this level, recharging it can be dangerous. An internal safety circuit will therefore open to prevent charging, and the battery will be (for all practical purposes) dead.\n\nIf you already have two Li-ion batteries for a given

You have to be more clear\n\nI think nobody here could understand your question

This should be able to explain it better than me.

pretty ambiguous question.

Um ... yes?\n\nHow the heck can we figure this out without links to the relevant information?  Or is reading your mind part of the question requirements?
