Cell Phone Batteries: The Power Behind The Phone
An estimated one billion cell phones will be manufactured and shipped in 2008. That's roughly one cell phone for every six people in the world, and while the cell phone market is still very much in the growth phase, there's another market which will be doing even better: the market for cell phone batteries.
The world will never return to the days without cell phones; it would mean having to give up too much convenience and security. But all of that convenience is completely dependent on the power sources for all those cell phones. Yet some cell phone batteries, ironically, are a threat to the very world which cell phones have made safer. Why?
Most early cell phone batteries were constructed of toxic nickel alloys. Lithium ion polymer batteries were developed as a lightweight, non-toxic alternative to the nickel alloy batteries which contained the highly toxic heavy metal cadmium.
Lithium ion cell phone batteries do have their strong points. They require minimal maintenance, as they hold their charges for a longer time than other kinds of cell phone batteries. And they can be recharged without having been completely depleted. The makers of lithium ion cell phone batteries, in fact, claim that they will perform better if they are still charged before being entirely depleted.
One of the biggest issues facing the makers of cell phone batteries has been that of cost. And lithium ion batteries are cheaper than nickel alloy batteries. In addition, they are available n multi-packs, further reducing their costs. But lithium ion cell phone batteries are still works in progress, so if you decide to use them, be certain to study their manufacturers' suggestions.
A further caveat is that where there is a market with demand the size of the demand for cell phone batteries, there are certain to be those trying to supply that demand with counterfeited products. There are many makers of counterfeited cell phone batteries who have no qualms whatsoever with making inferior batteries and labeling them as those from legitimate manufacturers.
Counterfeited batteries are subject to a host of problems, including the inability to be recharged because they do not properly interface with the chargers designed for the genuine lithium ion cell phone batteries. Such a mismatch is not merely inconvenient; it has been known to make the counterfeit cell phone batteries to burst into flames.
Counterfeit batteries are not the only problem; there are also counterfeit cell phone battery chargers which can ruin the good batteries and event the cell phones they are used to charge.
If you are just getting your new cell phone, it will include rechargeable cell phone batteries, but you'll have to condition them if you want to maximize their lifespan. Conditioning them means running them until they are completely depleted before you give them their first recharge. Why?
Cell phone batteries are designed with an internal memory which reads the batteries level and tells the battery when it is nearly out of power. That's why you'll get a warning on the screen of you cell phone when your battery is running dry. The first time you charge your cell phone batteries, charge them fully, and they will remember what their full capacity is in the future.
