What Is Car Battery And How To Use Automotive Battery Chargers
Lithium-ion batteries, which came into commercial use in the early 1990s, have a very high energy density and are less likely than most batteries to lose their charge when not being used -- a property called self-discharge.
Because of their light weight and low maintenance requirements, lithium-ion batteries are widely used in electronic devices such as laptop computers. Some experts believe that lithium-ion batteries are about as close as science has yet come to developing a perfect rechargeable battery, and this type of battery is the best candidate for powering the electric cars of the near future.
A variation on lithium-ion batteries, called lithium-ion polymer batteries, may also prove valuable to the future of EVs. These batteries may eventually cost less to build than lithium-ion batteries; however, at the present time, lithium-ion polymer batteries are prohibitively expensive.
Charge up your car battery while it is parked at home
Automotive battery chargers are designed to help you get the maximum car-starting power out of your automobile battery. The battery charger plugs into your mains electricity supply and converts the AC voltage to a small DC voltage that you can use to put your car's 12 V battery on charge while it is parked at home.
Automotive Battery Chargers
To keep your 12 volt car battery in peak condition Smart Battery Chargers Are Most Convenient. Automotive battery chargers a must have item for everybody's home garage or car port. if the car you own is less than a year old was a well-maintained company job that your employer looks after for you, then you may not need an automotive battery charger.
However, if the automobile you drive on his more than a few years old, then the 12 V battery inside it could already be on its way out. And if your battery is not in perfect condition, then there is a good chance that some morning when you're trying to get the car started, you suddenly find you have a flat battery.
When your battery is flat, and your car won't start... but chances are very high that you're going to be late for work. You could even be several hours late. If that happens, your employer is not going to be happy with you. You may receive a verbal warning, or it could even get you a written warning. Neither one is good for your career path, and who wants that kind of hassle anyway if problems like this can be avoided.
Well, the flat battery problem is easily avoided by replacing your car battery every couple of years. However that is wasteful, because in many cases there is nothing wrong with the battery you have just thrown away. Thousands of people do this, but the better way is to have your own automotive battery charger and to use it to keep your car battery fully charged by giving it a boost every couple of weeks or so.
There is several kinds of automotive battery chargers you can choose from, and all you have to do is to thumb through a catalog from your local art supply store or even your supermarket, K-mart or Wal-Mart store.
The cheapest and simplest kind of 12 volt car battery charger is the trickle charger. This uses a small electrical transformer to drop down the 110v or 220v AC mains voltage in your home to a little more than 12 volts DC current that can be used to fully charge your auto battery overnight overnight. One of these lightweight trickle chargers may need 12 hours or longer to fully charge your battery, so it isn't going to be any use to you if it's 7:30 AM, and your battery is flat, and you have to be at work by 8:30 AM.
There are numerous middle-range auto battery chargers as well. Usually they have a High and a Low setting, or they might be marked with two or three settings for different charging rates - such as 2 amps slow charge, 4 amps medium charge or 8 amps and higher for a fast battery charge. The higher the maximum charge rate, the larger the built-in electrical transformer needs to be, and the bigger, heavier and more expensive the battery charger itself will be.
Then there are several kinds of so-called 'smart' battery chargers at the higher end of your options. Higher in price and in features. These smart chargers have electronic circuitry inside that can examine your 12 volt car battery and determine how healthy or otherwise the battery is. If you have a completely dead, an open circuit or a short-circuited cell in your vehicle battery it will let you know right away. Otherwise you could be trying to charge the battery for days even, to no avail.
These smart chargers are designed to charge a weak battery at a faster rate (higher amps) and to sense automatically - usually by small voltage changes) when the battery has been charged enough.
The devices then switch to a tiny trickle charge that will keep the battery in best-possible condition without over-charging it, An over-charged battery will usually get very hot. This can buckle the metal plates (electrodes) inside and evaporate the liquid electrolyte as hydrogen gas - which can be explosive.
So do look at several choices of possible battery charger for your car, ask plenty of questions, read the manufacturer's brochures and then make up your mind which one is right for you.
