The good news about lithium ion batteries? They pack more energy into their rechargeable frames than any other kind of rechargeable batteries.
The bad news about lithium ion batteries? About .000003 percent of the time they spontaneously burst into flames. And if one particular run of lithium ion batteries seems to be bursting into flames more frequently, all the batteries from that run are recalled.
The other drawback to ion batteries is that just like human beings, as soon as they are born, they begin to die. They do so even if you leave them in their packaging on a shelf until you are ready to use them. Many rechargeable batteries, with proper care, will last for a decade. Not so for ion batteries. The brightest stars in the rechargeable battery firmament, they perform brilliantly for a brief two to three years, and are gone.
The Recharging Difference
But during their brief life spans, ion batteries are quite user friendly. They do not require that your recharge them fully before using them; most rechargeable batteries suffer “memory loss.” If you do not let them discharge completely and then recharge them fully, their energy capacity will gradually diminish.
Ion batteries, however, remember how full they are supposed to get, and even if you only have time to recharge them a fraction of their energy capacity, they will be willing and able to be filled to the brim at the next fill up.
Even better, ion batteries do not demand that you let them run down completely before recharging them; you will, in fact, ruin them if you do! Other rechargeable batteries will require you to have a spare ready that you can keep going when the first one gets exhausted and sent to the battery charger; then you have to let the new battery fully discharge before using the older one.
If your schedule allows you to do without your rechargeable non-ion battery during its four hour visit to the battery charger, of course, you don’t need to worry. But because it’s usually impossible to tell when a battery will fully discharge, you may get caught in a very awkward situation if you don’t have a backup battery on hand.
The Crystallization Factor
The “other” rechargeable batteries, with nickel based chemistry, are also prone to developing electrolyte crystals on their plates if they are repeatedly overcharged. Crystallization can increase voltage resistance and lower some of the energy produced by the battery’s separate cells. If you are using a “trickle” battery charger, be very careful to remove your nickel based batteries as soon as they are fully charged, because trickle chargers are notorious for overcharging batteries.
Or simply toss out your nickel based batteries and start using ion batteries which do not develop crystals. Keep your ion batteries in a cool place, even a refrigerator if you like, until you want to use them. Never let them get overheated; excessive heat will accelerate their degradation process. So turn you laptop off when you are not using it, because it’s warm inside!

Positive And Negatives Of Dvd Car Systems
Car video systems are really catching on and many families are purchasing them to install in their present vehicles. The positives of having one in your car would probably include the following reasons, especially if you have children.
1. They keep the children occupied with something to do other than to tease and torment each other while in the car.
2. Car DVD systems give the back seat occupants something to view other than the back of someone’s head and scenery speeding by on the side. To children it is more entertaining than beautiful scenery.
3. DVDs cut down on car sickness for some reason. Maybe it is because they are concentrating on something instead of the world rushing by.
4. It keeps the drivers attention up front instead of who is doing to whom in the back seat. This is essential as we all know.
5. The car is quieter (if you use ear buds) and at the end of a long day this makes the driver and other occupants less tired, nervous and cranky.
6. A conversation can be taking place between the adults while the children have ears buds in their ears and are being entertained.
7. If the electricity in the house goes out then the car video could be a source of entertainment for an otherwise long dark evening.
8. Wrecks are less likely to happen due to flying objects from the fighting going on in the back seat.
9. On a camping trip when the mosquitoes invade your camp site it could be used as a safe haven for a couple of hours instead of sitting around the campfire.
10. The words “Are we there yet” is heard much less in that whinny irritating voice which is one great blessing.
On the other hand there are some negatives which can and need to be avoided with just a little care.
1. Car video players can be watches by all occupants of a car, except the driver. ---DUH
2. Ear buds are a must especially if each child has their own DVD players; otherwise, fights occur about volume adjustments. Buy a variety of sizes just in case, and always carry spares.
3. Be sure you buy the whole component with the DVD include, not just the monitor. A blank monitor makes for boring viewing. Get an all-in-one DVD player with video cassette player, DVD player, speakers and screen.
4. One DVD disc will not do. You need to bring a variety of discs.
5. Car entertainment systems can be attractive to thieves. Install an alarm or buy a removable one.
6. Older cars may not have an electrical system to handle the demands of a DVD system.---Try a portable one.
7. In dash units usually won’t play unless you are parked. -----Thank goodness
When you decide to buy a car video system remember that you will be cheating your child out of some of your most memorable moments of traveling in the back seat for three days going to Grandma’s house. Your child’s vocabulary will probably not include the repeated phrase, “Are we there yet?” How unfortunate.

Solar Air Conditioning Is For Everyone
One of the best ideas to come along in a very long time is the idea of solar air conditioning. Simplicity itself, the system has nonetheless been overlooked for far too long. As the technology of this system grows, the popularity of it will also spread. The system makes basic common sense when you consider that the main season we need air conditioning is also the season with the strongest direct sunlight.
The technology of solar air conditioning would benefit from this abundant supply of free sunlight power to run the air conditioning elements. With the power source being free, the solar air conditioning system would quickly replace the more common systems in use today.
Environmentally Friendly and Cost-Effective
The solar air conditioning system has many of the same internal elements as the more conventional units except that the power source comes from ultraviolet rays from the sun rather than electrical power. The solar air conditioning system uses the power of the sunlight to run the system all day long, and the residual power (stored up in batteries) would be able to keep the unit running through the night as well.
Solar Air Conditioning Benefits
The solar air conditioning system is very good for the environment, as it uses no electricity (created from the burning of diesel fuel in electrical plants). Conventional air conditioners use a vast amount of electricity to create cool air in systems that are not always as efficient as they should be. The fact that the energy source for these solar air conditioning units is free is simply a cost-saving bonus. The savings on your electrical bills alone will make this system worth having in your home. Remember though, that even though you use free sun power for these units does not mean that the cost to you is nothing. You still have to make sure that your unit is properly serviced and maintained for it to work right. Having regular service checks done by professional air conditioning technicians will prolong the life of your unit.
As the popularity of these units and their technology increases, more people are recognizing how efficient a system solar air conditioning really is. Do your research and find out if this system is the right one for you. You will be saving money and helping out the environment as well.

Best Digital Voice Recorders
Gone are the days when you used the audio tape to record the voice. The all new digital voice recorders have made all to forget the conventional tape and has offered us more features than we can use. So a tape is now obsolete and has been taken over by the digital voice recorders. This small gadget has been quite useful since its launch and a great boon for professionals as well. So if there is a need to record voice, a digital voice recorder is what you should look for.
The digital voice recorders come as a handy solution for the busy business people who need to record notes, meetings, and ideas that can create a fuss if a tape would be used, instead of the digital voice recorder. A digital voice recorders is not all about recording voice, but it also has the capability to record and transfer information to your computer, making it easier to organize, edit and play back your voice files wherever you want.
With the increasing popularity of the digital voice recorders, there are many leaders in the electronics industry like Sony, Panasonic, Samsung, LG that provide the best digital voice recorders. But while buying a digital voice recorder, there are a few aspects involved in the selection of the best that you need to understand beforehand. So lets understand what a digital voice recorder is all about.
Look for the recording time.
Many digital voice recorders boast of the recording time by claming the higher side of it. The recording time depends on the quality of recording and the higher the audio quality the lower the recording time would be. So rather than looking for a recorder that claims 300 Hrs of recording, look for the real picture of the recording time it can give with the highest quality.
Look for more storage options
Apart from voice files many digital voice recorders can store files, documents and images. These are equipped with the USB mass support class that helps them to store these files. Now with the storage comes the organizer, which is also an important feature to look for. Be sure that the digital voice recorder will store voice files in a minimum of three separate folders.
Look for voice recording features
The best of the digital voice recorders also exhibit many ‘smart’ features that help you with the operations. Some of the interesting features you can find in the latest digital voice recorders are voice activation, which stops recording automatically whenever there is a long pause, or the cue/review feature that make it easier for you to find a particular recording part you want to play back. It can also have a LCD screen for better operations. Some of the latest voice recorders also include software, which helps in converting the audio in a text file helping you with the transcription.
Look for connectivity
Like any other latest gadget the digital voice recorders are equipped with USB interface for PC connectivity. It helps a lot in transfer of files from the recorder to PC and vice versa.

Dvd Recorders Reviews
If you see a VCR now a day, it generates curiosity and it is also possible that it will take time to understand the functionality. More so because the VCR’s are now almost obsolete and are replaced by the high-end DVD players and recorders. A DVD recorder is an electronic device that contains an optical disc recorder, which records the data or a video onto blank writable DVD disk. The DVD recorders are available as either installable drives for computers or as standalone components for use in studios or home theater systems. If you are using your VCR for quite a time now, the DVD recorder will offer you more advantages over a conventional VCR system. Though the rivalry is debatable, it is very much about a host of added features that will make the DVD recorder win the race. Some of the basic advantages of the DVD recorders compared to the VCR are as follows.
· With help of the DVD recorder you will experience superior video and audio quality, that is not offered by the conventional VCR
· Compared to the video tape, the DVD is an easy to handle and smaller in size and can contain more data as well in the form of increased recording time.
· It allows random access to video chapters or files without rewinding or fast-forwarding
· Another great feature us the onscreen multilingual subtitles and labeling that is not available on VCRs
· The quality of the media and the optical reader reduces playback wear and tear
· It also allows high-quality digital copying, with little or no generation loss
· It features improved editing, at least on rewritable media
· You can have the playlisting done with your DVD recorder
· It eliminates the risk of accidentally recording over existing content or unexpectedly running out of space during recording
· Easy to find recordings due to chapter menus
This features greatly increase the popularity of a DVD recorder and it is rightly received by the market leaders as well as they offer a wide array of DVD recorders. Some of the leading manufacturers of the DVD recorders are Sony, Panasonic, JVC, Phillips etc. They offer the DVD recorders with some great features, which makes the experience of using them even more delightful. A number of manufacturers have gone further and have combined DVD recorders with hard disc-based digital video recorders, allowing for simple recording to large fixed disks, and the ability to spool these recordings off the DVD at a later date.
A good DVD recorders can record analog TV via over-the-air broadcasts, cable, or satellite, standard definition digital television (SDTV), same quality as DVD-Video (480i), analog camcorder video (8mm, Hi-8, VHS, and VHS-C formats), digital camcorder video (miniDV and Digital-8 formats). It is a better idea to read the reviews and compare the DVD recorders on features, price and up gradations. Read the reviews carefully before rushing to buy it.
