ealed lead acid battery quick capacity test can give you the most up to date diagnostics regarding the capacity of your battery within seconds. This can tell you if you need to charge your battery a bit longer or even if you have overcharged your battery. By using a quick capacity test, you can find out right away if your battery is in good shape.

Sealed lead acid batteries are sold today for cars, electric vehicles and other items. They are completely contained and harness electrical power. They can be recharged but cannot be overcharged. One of the primary mistakes that people make with rechargeable batteries is to leave them in the charger for too long. This can actually damage the battery so that it is no longer viable.

Rechargeable batteries can be expensive to replace. This is one reason why you want to maintain the battery that you have. If you have an electrical transport, for example, you want to be certain that this vehicle is in working order at all times. It is crucial that you charge the battery. This is often the case for those who have small electrical vehicles that get them around gated communities and campgrounds. These generally run on electric power that is stored into the battery. This makes for clean air use but the battery is rendered useless if it is not properly maintained.

Using the sealed lead acid battery quick capacity test is the best and quickest way to check the battery of your vehicle. You do not even have to remove the battery from the device in order to perform this test. If you are new to the idea of charging a battery, you can use this testing device so that you understand exactly how long you should charge your battery.

Some sealed lead acid batteries have quick charging devices that are available to them that can charge the battery within four hours. When you are charging a battery, you are essentially providing it with electricity that can be portable. Batteries have been around for a long time and have always been a way to store energy. Because we are more environmentally conscious these days, we are looking for batteries that can be recharged instead of those that have to be discarded which are not biodegradable and can harm the soil.

No matter what type of battery that you use for your electric vehicle, you should be certain that it is properly maintained and charged when needed. If you forget to charge the battery or over charge it, you will eventually harm the battery to the point it will be useless and you will have to purchase another battery.

Take care of your sealed lead acid batteries by charging them as directed and by regularly testing them with sealed lead acid battery quick capacity test. This only takes a few minutes and can end up saving you a lot of money as it can actually allow you to keep your battery for a longer period of time.

Anna Woodward asked:


Lithium batteries are primary batteries that have lithium metal or lithium compounds as an anode.

Depending on the design and chemical compounds used, these batteries can produce voltages from 1.5 V to about 3 V, twice the voltage of an ordinary zinc-carbon or alkaline cell.

These are used in many portable consumer electronic devices, and are widely used in industry. The term “lithium batteries” refers to a family of different chemistries, comprising many types of cathodes and electrolytes.

The most common type of these used in consumer applications uses metallic lithium as anode and manganese dioxide as cathode, with a salt of lithium dissolved in an organic solvent.

These offer high energy density, high capacity and long cycle life in the most common, lightweight sizes – with no memory effect. These cells, which operate over a wide temperature range, are ideal for many portable electronic devices – including rugged military equipment. This chemistry is superior to nickel and lead-based chemistries and the applications are growing as a result.

Lithium-Ions (sometimes rendered Li-Ion) are the pinnacle of camcorder technology. They offer quick charge times, long life, steady discharge characteristics, low weight and small size.

These offers about 40% more charge capacity than a NiCd battery of similar size and weight and can be fully charged in less than half the time. These are also the most expensive type of camcorder power cells available on the market today.

Unlike the other technologies, you can keep your Li-Ions fully charged: go ahead and top off a 90% charge back up to 100%. Otherwise, care and handling is the same as you are accustomed to. Keep them cool, dry and safe from shock. Be sure to recycle them when they’re ready to be discarded.

How to Prolong Lifespan:

Research is focusing heavily on these new chemistries, so much so that one could presume that all portable devices will be powered with these advanced technologies in the future. In many ways, this chemistry is superior to nickel and lead-based chemistries and the applications for this newer advancement are growing as a result.

Lithium batteries provide 300-500 discharge/charge cycles. It prefers a partial rather than a full discharge. Frequent full discharges should be avoided when possible. Instead, charge more often or use a larger battery. There is no concern of memory when applying unscheduled charges.

These are memory-free and in use typically lasts between 2-3 years. The capacity loss manifests itself in increased internal resistance caused by oxidation.

Eventually, the cell resistance reaches a point where the pack can no longer deliver the stored energy although it may still have ample charge.

An aged battery can be kept longer in applications that draw low current as opposed to a function that demands heavy loads. The speed by which lithium-ion ages are governed by temperature and state-of-charge. Not only is it better to charge these at a slower charge rate, high discharge rates also contribute the extra wear and tear.

This is a low maintenance battery, an advantage that most other chemistries cannot claim. There is no memory and no scheduled cycling is required to prolong the battery’s life.

In addition, the self-discharge is less than half compared to nickel-cadmium, making Li-Ions well suited for modern fuel gauge applications. These cells cause little harm when disposed.

Advantages:

* High energy density – potential for yet higher capacities.

* Does not need prolonged priming when new. One regular charge is all that’s needed.

* Relatively low self-discharge – self-discharge is less than half that of nickel-based batteries.

* Low Maintenance – no periodic discharge is needed; there is no memory.

* Specialty cells can provide very high current to applications such as power tools.

Limitations:

* Requires protection circuit to maintain voltage and current within safe limits.

* Subject to aging, even if not in use – storage in a cool place at 40% charge reduces the aging effect.

* Transportation restrictions – shipment of larger quantities may be subject to regulatory control. This restriction does not apply to personal carry-on batteries.

* Expensive to manufacture – about 40 percent higher in cost than nickel-cadmium.

* Not fully mature – metals and chemicals are changing on a continuing basis.

ll batteries then you probably already know that your customers need to know when they buy a battery that it?s charged and fully functional and ready to go. After all, that?s the main purpose of having a battery in the first place. It?s important for customers whenever they buy any kind of battery, but it?s very important when customers are buying batteries to use in their UPS battery backup systems. If you sell replacement batteries for UPS battery backup systems, the best way to prove to a customer that the batteries you are selling are high quality and fully functional is to test that battery for the customer using a good battery tester. Obviously if the person is ordering a battery from you over the Internet or the phone you can?t test the battery right in front of them, but it is still just good customer service to test that battery before handing it off to a customer. Testing a battery before selling the battery is also good protection for you. If a customer decides that he or she wants money back and says that the battery is faulty, you have already tested the battery and the customer knows it was working at the time you sold it. If you have proof that the battery was not defective when sold, then often you can protect yourself from credit card chargebacks or having to give a refund.

Whenever you sell a product like a battery that is only worth something if it works it?s a good idea to test the product before a customer tries it with an APC UPS backup battery tester. Sometimes batteries will be defective, or old, or will simply not work. That?s just part of doing business. But if you use a proven battery tester to test each battery before you put it out on the sales floor, then you can catch the batteries that don?t work and the batteries that have a low charge and keep them from getting into your customer?s hands. It?s better to pull a battery off the shelves then to leave it on the shelves and have to deal with an angry customer after it sells, the customer takes it home or to their office and finds out it doesn?t work. Chances are the customer won?t test the battery, but will just install it and you won?t find out that the battery was defective until the customer calls you angrily to tell you that the battery backup failed and the customer lost important data. No battery seller wants to have that happen. So your best bet is to test your batteries with a battery tester to be sure that doesn?t happen.

Mitz asked:


Digital Camera Tips

By Mitz

A few years ago I started selling on Ebay, Which in turn, demanded the use of a Digital camera. I would take at least 50 photos a day, and sometimes up to 100. You would not believe how many batteries I went through until I realised how to save and preserve my precious digital cameras battery life. Take it from me, I never loose that great photo opportunity because my batteries have unexpectedly run out.

Get the right battery for your digital camera

I was lucky because my digital camera came with a lithium rechargeable battery and also took AA rechargeable batteries also. However, since I was a total amateur with digital cameras, I promptly ruined the lithium battery by not letting it run out properly before charging it again. Now I just use Ni-MH AA rechargeable batteries with at least a mAh rating of 2300. I have had rechargeable batteries that had a rating of 1600 and they were absolutely hopeless!!! You must have rechargeable batteries, wether it be a nickel cadmium, lithium ion or lithium polymer battery.

Turn off your flash on your digital camera

As I was taking pictures in broad daylight, there was no need to use my flash. Not only did it ruin the photo with a bright glow, but it consumed my battery power like a hungry animal. To find out how to turn the camera flash off I had to search the internet as I had lost my digital camera user manual.

Using the Lcd Screen was a big power user

I quickly learned that instead of browsing through the photos on the camera, I would wait until I had transferred them to the computer. The little harmless LCD screen on the back of most digital cameras is a total power hog.

Also if you do not need the LCD screen on, your batteries will last so much longer. Don’t forget that you can still look through the viewfinder to take a picture (like they used to in the good old days). Also see how to clean your LCD screen

Use your Power Saving Mode

Turn on your power saving mode for your digital camera. It almost works like a screensaver and can put your camera in sleep mode if left on by accident. It is usually a simple setting in the menu of your camera.

Avoid zooming in and out.

If you were just playing with your digital camera and started zooming in and out constantly, your batteries would be dead within 10 minutes, whereas they would usually last 2-3 hours. They may even be dead flat within 5 minutes, depending on what type of zoom you have.

Taking video clips with your digital camera

This is a big power user. The camera is made for digital stills and usually has the extra feature of being albe to take video clips. Not only does it take up room on your storage space, but it also uses your battery power

very quickly. If you do plan to take video clips with your digital camera you should be sure that you have more batteries on hand. I usually take videos with the leftover battery power I have left when I have finished taking all the photos I need.

In cold weather, keep your camera and batteries warm in your jacket until you are ready to use them. The cold drains batteries very quickly.

Carry spare batteries at all times

Why risk loosing that great photo opportunity because your batteries in your digital camera just happen to run out. Carry a spare set of digital camera batteries, it’s not rock science. For example, at one of my children’s sports day carnivals, another mother had to ask me to take photos of her child as well as mine, as her batteries in her camera just died unexpectedly. Because she was not prepared, she had to trust that I would catch that special moment for her child.
