Technological evolution of cell-phone batteries<\/p>\n
Apart from a \"hello\" or some other warm greeting, I have had
\nrecipients answer my call first with \"Sorry if the line cuts off,
\nmy cell phone is 'lowbat'.\" Then a click. Then a disconnection.<\/p>\n
Well, you might say, why don't they just go and purchase a new
\nbattery for their cell phone? Or, why not go to Glodok Jaya, a
\nshopping center in Kota, downtown Jakarta, to get their batteries
\nrepaired at very reasonable prices. Thanks to technological
\nadvancements, newer versions of replacement batteries usually
\nlast longer than the original batteries which came with cell
\nphones.<\/p>\n
Indeed, the number of cell-phone users has increased
\ndramatically in recent months. But many of them do not really
\ncomprehend how long their batteries will last, though they are
\nracing to buy the most sophisticated, latest models.<\/p>\n
Cell phone batteries will last for several years; however,
\naccording to some battery manufactures, batteries used on a
\nregular basis should be replaced every year.<\/p>\n
It actually depends on the type of battery used. The first
\nbatch of cell-phone batteries is the Nickel Cadmium (NiCad),
\nfollowed by Nickel Metal Hydride (NiMH), Lithium Ion (Li-Ion) and
\nLithium Polymer.<\/p>\n
NiCad batteries are now out of date as NiMHs and Li-Ions are
\nnow more popular and have no memory effect, which means users can
\nrecharge them at any level. Memory effect occurs when the
\nbatteries can no longer hold a full charge, resulting in a so-
\ncalled \"false peak\".<\/p>\n
There is no need to wait until they are completely discharged
\nbefore recharging. These batteries will also last two times to
\nthree times longer than NiCad types and 30 percent longer.<\/p>\n
Battery traders at Glodok even say that they can alter your
\nNiCad packs to be replaced with NiMH, and that users can use
\ntheir current NiCad charging system. But, for optimum results, it
\nhas always been advised to use the actual NiMH charger, to help
\nprevent overcharging and allow for maximum capacity. Overcharging
\na NiCad has always been a problem, and severely shortens its
\nlifespan. NiMH offers greater talk and standby times than
\ncomparable NiCad and do not require discharging entirely prior to
\nrecharging.<\/p>\n
Li-Ion battery technology is a breakthrough in cell-phone
\npower source option. The batteries are prepared to assure highest
\nquality and customer satisfactory. The advantages include: no
\nmemory effect, higher capacity, smaller size, double capacity
\nover NiCad battery, longer lifespan and up to 1,000 times
\ncharging cycles. Li-Ion tends to offer the highest energy density
\nfor extended talk-times in a lightweight package with the lowest
\nself-discharge rate.<\/p>\n
Cell-phone makers are now competing to apply the best in
\nbatteries. Motorola was the first to introduce Lithium technology
\ninto cell phone applications in 1993. Newcomers like Samsung also
\napply Li-Ion batteries.<\/p>\n
Currently, battery producers are researching Lithium Polymer
\ntechnology. Few cell-phone makers have tried to apply this
\ntechnology on their handsets, but get disappointed as it does not
\nmeet the required standards.<\/p>\n
The type of battery users choose to use with their handsets
\nwill determine the length of talk and standby time as well as the
\ntotal size and weight of the phone.<\/p>\n
There are many factors relating to the weight of a battery,
\nincluding the milliampere hours (mAh) and the design, which is
\nslim or vibrating. (I. Christianto)<\/p>",
