Nickel Battery Charging Basics


NiCad and NiMH batteries are amongst the hardest batteries to charge. Whereas with lithium ion and lead acid batteries you can control overcharge by just setting a maximum charge voltage, the nickel based batteries don't have a "float charge" voltage. So the charging is based on forcing current through the battery. The voltage to do this is not fixed in stone like it is for the other batteries.

This makes these cells and batteries especially difficult to charge in parallel. This is because you can't be sure that each cell or pack is the same impedance (or resistance), and so some will take more current than others even when they are full. This means that you need to use a separate charging circuit for each string in a parallel pack, or balance the current in some other way, for example by using resistors of such a resistance that it will dominate the current control.

The coulometric charging efficiency of nickel cadmium is about 83% for a fast (C/1 to C/0.24) charge, and 63% for a C/5 charge. This means that at C/1 you must put in 120 amp hours in for every 100 amp hours you get out. The slower you charge the worse this gets. At C/10 it is 55%, at C/20 it can get less than 50%. (These numbers are just to give you an idea, battery manufacturers differ).

When the charge is complete oxygen starts being generated at the nickel electrode. This oxygen diffuses through the separator and reacts with the cadmium electrode to form cadmium hydroxide. This causes a lowering of the cell voltage which can be used to detect the end of charge. This so-called minus delta V/ delta t bump that is indicative of end-of-charge is much less pronounced in NiMH than NiCad, and it is very temperature dependent.

As the battery reaches end-of-charge oxygen starts to form at the electrodes, and be recombined at the catalyst. This new chemical reaction creates heat, which can be easily measured with a thermistor.. This is the safest way to detect end-of-charge during a fast charge.

Nickel cadmium battery chargers should cut the charge off when the temperature exceeds the maximum charging temperature, typically 45 degrees C for a controlled fast charge, and 50 degrees C for an overnight or fast charge.

Rust Removal the Scientific Way


Rust is one of the biggest culprits that make your possessions look unsightly and even render them useless when left unattended. Rust is iron that made contact with oxygen, and forms an unattractive stain in your metals and other materials in your house that contains or is made up of iron. Aside from employing various methods to protect your materials from the formation of rust, you can also use many rust removal products. Over the years, many rust removers have already been developed that are cost-efficient, effective and can save your materials from rotting with rust.

Metal rust removers come in various forms and techniques. One of the most popular ways of removing rust manually without the use of rust removal products is through electrolysis. If you have paid enough attention to your sixth grade science teacher, you would know that rust is a product of iron making contact with oxygen. So basically, the process of removing rust is the transformation of the surface reeking of rust back to its original form - iron.

All you need to use are the following: a stainless steel, a plastic tub, washing soda, water and a battery charger. Place a tablespoon of the washing or baking soda to a gallon of water. This serves as the removal solution. Clean the piece of stainless steel to be used for the rust removal process. It is crucial that the steel is cleaned enough to ensure that enough electric contact is achieved. Attach the positive side of the battery charge to the steel and submerge it in the soda-water solution. Attach the negative side of the battery charger to the material you wish to be cleaned. Submerge this piece to the solution as well. Make sure that the material and the stainless steel do not make any contact as this might lead to a short circuit. Now it's time to turn the battery charger on. If the current is too high, you can either increase the distance between the stainless steel and the material to be cleaned or add more water to the solution. Once done, you should see bubbles of oxygen and hydrogen in the solution. The time to wait before all speck of rust is removed varies on the size of the material and how much rust has accumulated on it.

Unregulated DC Power Adapters


Regulated or un-regulated: what does it mean?
A voltage regulator is a device (usually an electronic circuit) that controls or maintains the constant voltage output of a power supply. Some (more expensive) DC voltage output power adapters have voltage regulators built in, while most do not.

Unregulated DC output power adapters are still the most common type of power adapter in use today. Unregulated, or "non-regulated" simply means the power adapter is not subject to the control or authority of a voltage regulator. With unregulated power adapters, or any other unregulated DC power supply, the DC output voltage is dependent upon an internal voltage reduction transformer, and related to the amount of current used by the electrical load. (The load is the device receiving power from the adapter).

Example: A given unregulated power adapter has an output rating of 9 volts DC at 500ma (500 milliamps = 0.5 Amps).
This rating means that the unregulated voltage output of the power adapter will be 9 volts DC when it is under the full rated load of 500ma. Many people are surprised when they plug an unregulated power adapter into a wall outlet and measure the DC output voltage of the power adapter with a volt meter. While the adapter is providing no power to a load device, the measured output voltage is several volts higher than the rated voltage of the power adapter. Often, people jump to the conclusion that something is wrong with the power adapter, while the simple explanation is that the power adapter has no voltage regulator, and this is normal. But if the same unregulated power adapter is connected to a load which draws 500ma of current, the measured output voltage of the power adapter would drop to the rated 9 volt DC output level as it should.

The second important concept to understand about any power adapter, whether regulated or unregulated, is that the rated output current of the adapter should not be exceeded by the maximum current requirement of the load.

Example:  If a power adapter has an output current rating of 500ma, it should never be connected to a load that will draw more than 500ma of current from the adapter. Drawing more than the rated current output from an unregulated power adapter will certainly cause the actual output voltage to drop below the rated value, and overloading any power adapter in this way will lead to overheating and premature failure of the adapter. Overloading a power adapter may cause a fire hazard and depending on the power sensitivities of the load, may cause damage to the load as well. Most power adapters made today, have built in overload protection (essentially an internal fuse to prevent the adapter from going up in a puff of smoke), but overloading the adapter may still cause it permanent damage. Appropriate external fuse protection can be added if the extra precaution is warranted.

A third concept about unregulated power adapters which for most applications is less important, but still helpful for people to understand, is that unregulated DC output power adapters do not produce a pure and "clean" DC voltage. But if the power adapter selected is closely matched to the power requirements of the load, the purity of the DC voltage produced is more than adequate for many jobs (with few exceptions).

Find out how to prolong battery life by using correct charge methods.


Charging and discharging batteries is a chemical reaction, but Li-ion is claimed to be the exception. Battery scientists talk about energies flowing in and out of the battery as part of ion movement between anode and cathode. This claim carries merits but if the scientists were totally right, then the battery would live forever. Scientists blame capacity fade on ions getting trapped, but as with all battery systems, internal corrosion and other degenerative effects still play a role.

The Li ion charger is a voltage-limiting device that has similarities with to the lead acid system. The difference with Li-ion lies in a higher voltage per cell, tighter voltage tolerances and the absence of trickle or float charge at full charge. While lead acid offers some flexibility in terms of voltage cut off, manufacturers of Li ion cells are very strict on the correct setting because Li-ion cannot accept overcharge. The so-called miracle charger that promises to prolong battery life and gain extra capacity with pulses and other effects does not exist. Li-ion is a “clean” system and only takes what it can absorb.

Renew Your Old NICD Rechargeable Batteries


Nickel cadmium or NiCd was the first type of portable rechargeable battery and in many ways is responsible for revolutionizing the use of electrical devices, particularly cordless power tools. Battery technology has advanced considerable since the first NiCd battery was introduced and many devices are now powered using lithium-based cells which produce increased voltage, have more endurance and, specifically, are not prone to suffering from power loss. However, if you have old NiCd batteries that you think are dead and no longer usable, consider trying to renew them. Using a process of deep discharge may revive your batteries and give you up to another year of use.

1. Place your old NiCd rechargeable batteries into your charging device. Though you may have given up charging your batteries, you might find they still can take a charge. Turn on the charger and allow it to charge your batteries until the charger's "battery full" or similar light illuminates.

2. Turn off the device and remove the NiCd batteries once it stops operating. The time it takes before it stops operating depends on the condition of the battery. Leave the battery to rest for 15 minutes.

3. Insert the NiCd battery into the device again and turn it on. You may find that despite the battery appearing to be dead moments earlier that it still has some energy. The deep discharging process is beginning to break down the nickel-based cell structure in the battery. The reason your NiCd isn't retaining a charge for long is because the internal battery crystals have grown in size. Deep discharging breaks the crystals into tiny units; the smaller the crystals the more energy the battery can retain.

4. Leave the device running until it stops then repeat the process until you find the NiCd battery can't power your device. You may need to do this three or four more times, but it's worth doing.

5. Put your old NiCd batteries back on charge as soon as they are fully discharged, a process that can take a long time to complete. Leave the batteries charging until the charger indicates they are full. The next time you use your NiCd batteries you should find they have more power and last longer.

How to discern a charger


How to discern a charger depends on how its work performance, safety requirements and electromagnetic compatibility is.

Different types of batteries have different charging requirements, the parameters of a charger are mainly charging method, charge current, charge voltage.

(1) Charging method: how to charge is based on the constant voltage or constant current. Given the current lithium-ion battery, charger charging current with limiting constant voltage mode shall be adopted, that is, charging at constant voltage automatically converted when the charging at limited current to the limited voltage.

(2) Charging current: specifies the maximum output current of the charger. The size of the charging current shall be applied to the size of the battery capacity, generally should not exceed 1C5A.

(3) charging voltage: specifies the maximum output voltage of charger.The charging voltage is depends on limit voltage of battery charged; when charging the lithium-ion battery with nominal voltage of 3.6V, the maximum output voltage of charger required is typically 4.2V (in fact, the phone is equipped with a lithium-ion battery with protection device, so the charger output voltage can also be slightly higher than 4.2V, but the voltage is not more than 4.5V in order to ensure safety).

2. Safety requirements Popular terms is to ask the circuit structure, mechanical structure and electrical properties of the product shall comply with certain safety requirements, regardless of the product in a normal or abnormal operating state (such as output overload or short circuit, the internal component failure or circuit failure, etc.) work state, must not endanger the safety of persons and property. To achieve this purpose, the charger product safety requirements (such as electric shock protection performance, insulation performance, temperature, etc.) shall comply with the requirements of China mainland's compulsory standards as specified in GB4943-2001.

The History of Solar Panel Battery Chargers


The history of solar power battery chargers has to begin with the advent of solar power. Attempts to capture the power of the sun have been made since the dawn of man. Realizing its power to give heat and light, intrigued man from the beginning of time. Leonardo da Vinci studied the sun and ways to harness it in the fifteenth century.

Although modern science has taken away the romance of sun gods, mystical beings and other myths and tales, it has not lost its curiosity. Harnessing the suns power to be used in batteries has been around since France decided it needed an alternate energy source long before the fuel shortage of the seventies.

Charles Fritz managed to turn the suns rays into electricity with the first solar cell in 1883. It wasn't until later in the 1880's that a solar cell was used to warm water in his house. The studies went on. The possibilities of using up all of the nonrenewable resources was well known in the nineteenth century. People around the world still chose to use coal and other nonrenewable energy sources as though they would never end, or have any consequences.

Today the assortment of solar powered battery chargers is amazing. When you inventory your electronic gadgets, you know that everyone needs to be charged in one way or another. You will find out that most of those electric chargers can be replaced by solar battery chargers.

Laptop Charger Adapter Tips


Take Care of the Cord
Proper use and care of the laptop charger prolongs its lifespan so that replacements and repairs are not necessary. an online magazine for computer-related concerns, one of the most common problems with laptop use is that the charger's cord becomes frayed. Since laptops are conveniently brought just about anywhere, the constant plugging and unplugging wears out the cord. Mishandling it, such as leaving it twisted or tugging and jiggling it from the base unit, can produce the same result. This is also true for folding or rolling the cord incorrectly.

Store the Charger Properly
 As with laptops, which are typically placed inside laptop bags or padded envelopes, cords should be stored properly when not in use. The charger must never be exposed to extreme temperatures, such as those on a car's dashboard in the middle of summer or dead of winter. It must not become wet or be exposed to corrosive chemicals, as these elements can severely damage the charger. The manual for a Belkin Laptop Power Adapter, for example, specifically states that users must avoid these. It also instructs users to avoid placing the charger near heat-sensitive materials.

 When not in use, laptop chargers should be kept in the same bag as the laptop. If there isn't enough space, putting the charger in a convenient cloth pouch or a small box is also an option.

Keep a Backup Charger
 When traveling with your laptop frequently, it's a good idea to get a second charger adapter to avoid wear and tear. Having a back-up charger may also save you the headache of buying one in an unfamiliar place should your first charger adapter become damaged. a daily online travel magazine, recommends packing an extra power source, such as a portable charger adapter, when going on trips with your laptop.

How to Rebuild Cordless Power Tool Batteries ?


The batteries on cordless power tools are usually the first part to fail. If you've ever priced a replacement battery pack, you'll know that it is probably not a cost-effective purchase. Most people would rather buy a new tool than spend over half the price of a new tool on a replacement battery pack. The best option might be to rebuild the batteries, but only if you have some experience using a soldering iron.

1. Remove the battery pack from your cordless tool. Unscrew the screws holding the battery case together. Open the battery case. Remove the battery cells--they will all be wired together as a unit.

2. Draw a rough diagram of the battery cells on paper, noting the negative (-) and positive (+) terminals of each battery cell, and how each terminal is connected with wires.

3. Remove the connecting wires by holding them with pliers while melting the solder that holds the wire to the battery terminals, using a soldering iron.

4. Align the new battery cells correctly, according to your diagram. Solder all the connecting wires to the new battery cell terminals, according to your diagram. Work quickly so as not to overheat the batteries.

5. Slide the battery cells into one half of the battery case. Replace the other half of the cover. Fasten the screws that hold the case together, using a screwdriver. Charge the battery pack overnight before using it with your cordless power tool.

What is Switch Mode Power Supply?


The SMPS or power supply of a computer comes in different form factor styles. The form factor refers to the physical dimensions of a component. The form factor of the power supply must match with the form factor of the computer case into which the SMPS is inserted. There are various industry standard form factors available. Some of the commonly used form factors with their characteristics are given below:


1.    LPX
2.    ATX
3.    SFX

The LPX form factor style power supply has exactly the same motherboard and disk drive connectors as the previous standard power supply form factors. LPX form factor power supply differs in its reduced size that allows building much smaller and consumer oriented PCs. Due to their small size, they can be put into almost every type of computer cases.

The ATX form factor is developed by Intel in 1995. ATX is similar to LPX in physical dimensions. The difference between the two is that the power pass through-outlet for the monitor has been removed from ATX. Another difference is that in ATX, the cooling fan is mounted along the inner side of the power supply. With this kind of arrangement, the fan draws air in from the
back of the chassis and blows it inside across the motherboard.

The SFX form factor style power supply is 100 mm wide, 125 mm deep, and 63.5 mm in height. It includes a 60 mm power supply fan for cooling. The main SFX motherboard connector is in the same shape and size as the ATX connector. The one difference here is that the SFX power supply specification does not support the -5V compatibility voltage and, therefore, should not be used with motherboards that have ISA slots.

How to Test a Laptop Charger


Laptop computers are one of the many items that we use that depends on a rechargeable laptop battery to keep it up and running. When your laptop fails to stay charged or to charge at all, it is time to troubleshoot the issue on your own before paying a professional. First test the charger to make sure that it is working properly.

You can test your laptop battery charger follow the below steps

Be sure that the charger is plugged into a working outlet and getting power.

Try charging your laptop with the laptop powered off. Sometimes the charger will charge the laptop when it is powered completely off, but not when it is on. If it only charges the Toshiba laptop battery when the laptop is off, then you have a faulty charger.

Check the battery for corrosion and/or leakage. If there is a sign of either corrosion or leakage you will need to stop attempting to use the battery pack and replace it immediately.

Try to run the laptop from the laptop charger only; if it will not run off the charger alone then the charger is faulty or no longer any good to power the battery. In some cases your laptop will run off the charger, but the charger will not be strong enough to charge the laptop. In this case you have a faulty charger.

Test your charger with a voltmeter. If it is an AC charger of battery, set a voltmeter to 25 VAC. Make the contacts and probes touch, and look for a reading. If there is not a reading on the meter, the charger is not any good. For DC chargers, set a voltmeter to 25 VDC and make the contacts and probes touch. The meter should read at least 1V more than the chargers rating. If it does not, the probes need to be switched.
