Battery Chargers; What To Look For, What To Avoid.

Batteries, or dry cells are manufactured to supply steady and uninterrupted D.C power to different modern day gadgets that run with electrical energy. Batteries are generally lead-acid cells. Over 15 billion are produced every year and are sold worldwide. Many of these are alkaline-batteries which are discarded after being used for a single time. But there are also some which can be charged again and again after every use and are known as "rechargeable batteries". These should be kept at fully charged condition so as to meet the D.C. power demand whenever needed. Therefore suitable battery chargers are required to charge those types.

The different types of battery chargers are:

1) Medical
2) Automotive
3) Commercial
4) Industrial

These may be stationary or portable.

These rechargeable batteries are of high capacities. Rechargeable batteries, like Nickel-Metal Hydride (NiMH) or Lithium-ion (Li-ion) batteries can be charged several hundreds of times and last far longer period in high drain devices.

By using these repeatable charging batteries people can save tons of money. When the charge goes down below a certain level it stops supplying D.C power to electrical instruments, then the battery needs to be charged to regain its capacity of supplying D.C power. Low quality chargers can even damage batteries and shorten their lifetime. The charger takes current directly from electric lines and induces the electric charge into the batteries.

The charging of these depends on different factors such as its capacity, its age, its initial charges, etc. Different chargers vary widely in this matter. There is a tendency of generating heat during the charging of rechargeable batteries which is one of the most commonly cited factors for the damage of these battery. The heat mainly generates due to the internal resistance and chemical reaction of the rechargeable batteries. Excessive current can also damage the battery after it is fully charged.

There are some automatic chargers which initially charge at a very high rate and continuously monitor the cell voltage to reduce or shut off the charging when the battery tends to charge fully. The battery chargers can take 1 hour to 8 hour of time for charging depending upon the design and ratings of these chargers. There are also different visual indications like LED on the battery chargers. These indicators indicate that the rechargeable type batteries should
not get overcharged and help them preventing them from overheating.

Nowadays there are wide applications of rechargeable styled batteries. These types are even used in power generating stations as a substitute of D.C current and emergency Lighting System. They are also used in vehicles like cars, trolleys, bus, etc. There are also some battery driven cars which run on streets completely based on battery-power and not on fuel.

The use of rechargeable batteries can also be found in laptops, IPods, cellular phones, electric wheelchairs, etc. Therefore suitable chargers are essential for the charging of these re-chargeable batteries.

3 Hot Selling Notebook Computers

The laptop market is an overcrowded field with literally hundreds of offerings available to consumers. Some laptops are very basic models with Celeron processors while others are full blown multimedia powerhouses. Featured here are three top models from the “plain Jane” to the middle of the road, to the fully loaded.

Dell Inspiron 1200 – It is possible to purchase a notebook computer for considerably less than $1000 and Dell offers several models below this threshold including the Inspiron 1200. This particular model is the price leader amongst laptops especially when rebates are figured in. A recent Dell advertisement has been touting the Inspiron 1200 for just $499 after a $150For rebate is received. What do you get with this model? Not a whole lot: an Intel Celeron M Processor 350 (1.30 GHz/1MB Cache/400MHz FSB); Microsoft Windows XP Home Edition; 30GB Ultra ATA Hard Drive; and 24X CD Burner/DVD Combo Drive. Surprisingly, Dell does include wireless capabilities in the form of a networking card.

HP Compaq nx9600 Notebook – HP’s acquisition of Compaq has produced a nice line up of notebook computers including this particular model geared toward those consumers replacing their desktop computer. Retailing at just over $1300 [before $100 rebate] this midrange offering is nicely loaded as it offers a 17" screen; Microsoft Windows XP Professional Edition; an Intel Pentium 4 Processor with Hyper-Threading Technology; a 40 GB hard drive; a 12 cell battery; wireless connectivity; and graphics oriented software.

Batteries - Charging ahead

In these days of walk-and-talk and walk-and-work, battery chargers are as much a necessity to business as a microwave oven is to the kitchen. Cell phones, laptops, notebooks, and camcorders, just to mention a few.

But how do they work? Here are some types of battery chargers explained:

• Solar battery chargers: These little gems use the sun’s energy to recharge batteries. From car, boat and motorbikes to cell phones, DVD players and computers, there is a solar battery charger to suit.

• Automotive battery chargers: Most automotive battery chargers simply attach to the vehicle’s battery terminals and plug in to mains power. However, there are now new products on the market that work to prevent the battery from going flat in the first place. To comprehend how the process works it is important to understand what causes a battery to deteriorate.

Car batteries rely on a chemical process to provide power. The car battery contains lead plates in a solution of sulphuric acid, which act together to make and store electricity. Over time a residue of lead sulphate builds up on the plates, reducing the flow of electricity. “De-sulphating” technology reverses this process by using sound waves to dissolve the residue build-up.

Of course this won’t help if you’ve left your lights on at the train station …

• Industrial Battery Chargers: These are the big guys. With names such as ferroresonant, Opportunity Charging and Silicon Controlled Rectifier charger, these are heavy-duty long haul pieces of technology. Whether cold storage units, factory or fleet applications, there is an industrial battery charger to suit. Basically though, it is important that the industrial battery charger contains a voltage regulator of some description. This will ensure that the battery is not damaged while it is being recharged.

• Cell Phone Battery Chargers: It is very important to choose a cell phone battery charger that is designed for the model and type of battery being charged. Likewise, it is prudent to make sure that the battery is, itself, the correct one for the phone.

Choosing the correct battery charger will ensure that the connection points will be compatible and the correct amount of electricity is delivered. If too little electricity is delivered, the battery will not fully charge; if too much, it may overheat. Many cell phone battery chargers today do have a built in system to prevent overcharging, however, it is still important to ensure the charger and battery are compatible.

And to make sure that business, or life in general, isn’t inconvenienced too much due to battery recharging, many cell phone battery chargers now allow the user to make phone calls during the recharging process.

So, the next time you’re out and about walking the talk, spare a thought for the hard-working companion who makes sure your equipment is up to the job. And, the most important thing of all … never mistake that cup of coffee on your desk for your cell phone battery charger carriage.
