Published on: 04 March 2019 Last Updated on: 04 July 2020

Did your flashlight battery run out? If yes, then it will be good if you buy a new battery for your flashlight according to the recommendation from the manufacturers. If you follow the instructions or manuals given by the manufacturer inside then you can save your device from damages and wrong type of batteries.

While you are replacing the batteries make sure to check the details such as battery type, capacity, chemistry, dimensions, max pulse current, self-discharge rate, etc. It may sound complicated however it is necessary for good performance of the gadget.

Here we have small tips related to battery and its safety-

You must never recharge the battery with the wrong charger as well as do not charge primary batteries or it may explode and cause fires. Do not swallow the battery; keep your kids away from it. These NiMH and lithium batteries do not contain toxic metals but they are dangerous and when swallowed electrolytes will close the circuit in the body as well as cause chemical reaction which caused the ultimate death of a person.

Battery types:

Coin/ button cell battery:

These are grouped under no- rechargeable batteries. It is common in key chains, watches, remote controls, and hearing aids. There are various chemistry types of this battery like silver oxide, alkaline, and mercury oxide. In addition, most of the manufacturer interchangeably makes use of similar labels for silver oxide and alkaline batteries.

If you look at the button cell battery chart then you can find out the difference and also know about the button battery sizes.

Alkaline:

Alkaline coin/button cell batteries are cheap and reliable batteries. 1.5 volts is the nominal voltage of this battery but when you use this battery its voltage drops with time. The real capacity of this battery is dependent on the device cut off voltage. If it is to be used in electronic equipment where there is the requirement of the constant high voltage then the so-called capacity of this battery is low. In such gadgets the need for replacement of the battery is quick.

However, if the alkaline battery is to be used in gadgets that can tolerate low battery voltage, then its so-called capacity will be larger and you need not replace batteries in them so soon. Typical labels for alkaline batteries are LR##, AG##, LR###, etc. The normal capacity of alkaline LR44 is about 110-130 mAh and it is lower than equivalent silver oxide battery. Common Shelf life for it is 5 years.

Silver Oxide:

These button/coin cell batteries are a well-known type of batteries. They are not very expensive and have a shelf life of about 10 or more years. They have constant voltage while an operation that is identical to the nominal voltage of the alkaline batteries. Typical labels of this battery type are SR##, SG##, SR###, etc. Typical capacity of these types of batteries ex- Silver oxide SR44 is 150-200 mAh and it is more than equivalent alkaline LR44 while less than zinc-air.

Zinc Air:

These are used widely in hearing aid devices. They are having slightly lesser nominal voltage (1.4 to 1.45 V) however this voltage is quite similar or higher than the alkaline batteries voltage while using. In addition to this, these batteries got the largest capacity and chemistry. Typical capacity- 600-700 mAh and it is the much larger capacity when compared to silver oxide.

These batteries are not common because of different reasons, however, one of the common reasons is that they work by using air, and when electrolyte dries out, it is dead and needed to be replaced. Depending on manufacturer and model, after the protective tab of these batteries is removed, leave it for some minute in the air then use it for weeks. It has a shelf life of 4-5 years.

Mercury oxide:

These types of batteries are no longer in the use because of their impact on the environment. They require slightly lower voltage (~1.35V) they have good capacity. The typical capacity of battery MR44 is 180-200 mAh and it is quite similar to silver oxide SR44. If a small portion of these batteries is swallowed then it can induce vomiting.

Cylindrical batteries:

These are commonly used in devices such as remote control devices, key chains, bikes, electric tools, etc. Cylindrical batteries are divided into 2 groups such as-

Non-rechargeable or primary batteries
rechargeable or secondary batteries

It is to be noted that the primary batteries must never be charges. Also, keep in mind that does not recharge batteries with NOT designed charger. The nominal voltage of the non-rechargeable cell is 1.5V regardless of whether they are alkaline or carbon-zinc batteries. These are interchangeable nit alkaline batteries that have huge capacity and they are used more than the zinc-carbon batteries.

For Primary lithium batteries, nominal voltage is 3V; they have a larger capacity and are light weighted. In addition to this, they tend to be highly expensive than the zinc-carbon as well as alkaline batteries and are utilized in high power gadgets such as cameras, flashlights, etc.

Secondary cells’ nominal voltage is dependent on its chemistry. These batteries are smaller and packed with enough energy but if mistreated then it may burst or explode. Hence, make sure you refer a button cell battery chart before replacing or using any batteries in your device.

nickel Cadmium battery

it is also referred to as NiCd batteries and they have the nominal voltage of 1.2 V. it can generate large current however it has limited capacity as well as number of charging/ discharging cycles.

Nickel metal hydride– it is also referred to as NiMH batteries and it offers good capacity, low rate of self-discharge, good shelf life, etc along with reasonable rates.
Lithium secondary batteries– they have a voltage ranging from 3.3-3.7V and are labeled as 3.7 or 3.6V batteries. They have a large capacity, improved safety, and a higher drain.

For more information about batteries, you can refer button cell battery chart. We hope you have gained enough knowledge about batteries and their usage. Hurry up and go replace your batteries.

Do You Have an Old PC? Here’s What You Could Do With It

Do you have an old PC that you replaced with a newer model? Whether you’re an individual or a business or an organization, what you do with that old PC is a question that is worth thinking about. Many people simply decide to throw their old hardware in the trash – but not only is this highly wasteful, but it could also be a wasted opportunity or even a potential security breach. Any IT support professional will tell you how easy it is to retrieve data from an old PC – even a 20-year-old PC found in a landfill would have data on it that you could recover and read. For more info on what to do with an old PC, whether as an individual or as a business, we spoke to TechQuarters, an IT support provider that operates in North London. As they have been providing IT Support North London businesses have been relying on for years, they have a lot of experience managing their customer's PC and hardware. From that experience, they have suggested a number of different things you can do with an old computer, the least of which is to throw it out. Cleansing an Old PC No matter what you decide to do with a disused PC, the first step should always be to cleanse it of your data. As we mentioned earlier, anyone can restore the data on a hard drive just by using commercial software known as Data. Forensics software – so if you have anything on your hard drive you wouldn’t want other people to be able to access, such as bank details, passport info, etc. then you should make the effort to wipe the device. Before you start, you should backup your personal data, by copying it to another storage device – this might be your new computer, or it could be an external hard drive. Additionally, you should also locate any registration keys and serial numbers for software you have purchased, so that you can transfer it over to your new device – if you don’t do this, you might lose access to the software you have paid money for. Once you have backed up everything you want to keep, you should wipe the hard drive of your old PC. To begin with, restore the PC to its factory settings. This will superficially hide your data on the PC’s hard drive, but will not remove it – to do this, you will need to use a Disk-Wiping tool; this software will permanently overwrite your data with random information so that even if someone used Data Forensics, they would only find random data. What to do with an Old PC? So, once you have backed up all of your data and cleansed the old device of any personal data, what should you do with it? If your first instinct is to throw it away, think again. There are a number of things you can do to get a final return on your investment. 1. Sell for parts – depending on the condition of the PC, you can sell it for the hardware components. This is one way to get some money back from a PC that is too old for anyone to want to use it. The hard drive, CPU, RAM, Graphics Card, and even the Power Supply Unit is potentially valuable parts that others might find useful. 2. Sell as is – If your PC isn’t so old that nobody would want to use it, you could definitely sell it as a second-hand device. Just be sure to wipe your data completely, as someone else will be using it after you. 3. Recycle – If you’re not bothered about making any money back from your old device, and just want to be rid of it, feel free to dispose of it – but try and avoid letting it end up in a landfill. Instead, look for a service that can take the PC from you and recycle the materials correctly. Some computer hardware chains can do this for you. 4. Donate – Perhaps your PC is not that old, and you simply replaced it with a more powerful model. This means your old PC is still completely usable; in which case, you could donate it to an organization. For instance, schools, hospitals, and charitable organizations will all be likely to accept a second-hand PC as a donation. 5. Convert to a Server – Seeing as servers are essentially just PCs that have been optimized for a specific purpose, you could certainly consider turning your old PC into a server. Of course, this won’t be the easiest process in the world but is doable with the right guidance (which you can find online). To start with, a server needs to be running 24/7, so you will need to configure the device to run in a low-power state, make sure it doesn’t shut down at any inconvenient moments, and that it will run properly without any input – because you likely won’t want to have a monitor, keyboard, and mouse connected to it at all times.

5 Eye-Opening Reasons to Choose Certified E-Waste Recycling Agencies

Let’s see if this situation sounds familiar. You just bought the latest phone on the market. And, like any responsible citizen, you took the old gadget to an e-waste recycling center and deposited it. You walked out of the center confident that the old phone would be taken care of safely. You then forgot about the gadget altogether. Well! The story doesn’t quite end there. And, if you are an environmentally conscious person, you may want to take a closer look behind the scenes to identify what happens to the redundant and used devices once they leave your ownership. Did You Check for the Certification of the E-Waste Recycling Center? Should you check this feature on MoneyCrashers, you will come across an interesting observation. Delivering your e-waste to a recycling agency does not guarantee safe disposal. That’s because many such centers use unscrupulous methods to get rid of the gadgets. While the measures they use may comply with U.S. e-waste management regulations, they could cause severe damage to the environment in other offshore locations. The only way you can get complete assurance that the old electronics will be taken care of the right way is if you deposit them at certified recycling centers. Alternatively, you can exchange them at the original manufacturer. It might interest you to know that in the year 2015, Apple accepted and recycled 90 million pounds of electronic gadgets to extract usable materials. These materials included plastic, 6612 pounds of silver, 2.9 million pounds of copper, and 2204 pounds of gold. Choosing a certified e-waste recycling agency when getting rid of old and used electronics ensures that your gadgets will not end up in landfills and pollute the environment around your hometown. But, that’s just one good reason. Here are 4 more. 1. Recycling Agencies Choose Supposedly Economical Methods for IT Asset Disposal: You might think that you’re doing your bit to help the environment by recycling cell phones and other devices. But, keep in mind that although the recovered materials are valuable, the recycling process is not exactly economical for regular agencies. Extracting metals for reuse involves a careful process using the right kind of equipment and trained personnel. To save on the expense of dismantling old gadgets and separating the useful materials, most agencies simply ship them off to third-world countries. Would you like to know how the process works? Containers reaching the shores of the U.S. from Hong Kong and other vendor companies across the world are typically sent back empty after the goods are unloaded from them. In an attempt to cash in on the reverse transportation, the giant cargo boxes are now filled with used electronics and sent to Far East destinations under the guise of donations for philanthropic purposes. 2. Environmental Damage is Transferred to Third World Countries: When the gadgets make their way to countries like China, Ghana, and India, unskilled laborers including young children burn them in giant pits. Once the process is complete, all that remains is the precious metals that are sorted out without any regard for the toxic materials in the ashes. These poisons like arsenic, bromates, lead, and cadmium not only leach into the soil and underground water, but also cause various illnesses among the people who handle them or live around the processing plants. To know more about the extent of the damage, read this article in the Smithsonian magazine. If you’re looking for e-waste recycling procedures that protect the environment not just in your country, but also in any other location around the world, deliver your devices to certified agencies. 3. Irresponsible E-Waste Recycling is the Largest Cause of Data Breaches: Should you work with a licensed recycling company, the expert professionals will make sure to dispose of the hard drives in them securely. They may use DoD-approved multiple overwriting or shredding protocols to erase the data and make it impossible to decipher. Why is this important? According to PBS, The U.S. State Department has identified Ghana as the top sources of data leaks in the world. Hard drives from discarded electronics are easily available to hackers here at $35 apiece. Even novice cybercriminals can retrieve records of online transactions, credit cards, personal financial data, and various other kinds of sensitive information. Enoch Kwesi Messiah is a computer scientist at the Regent University in Accra. He reveals, “I can get your bank numbers and I retrieve all your money from your accounts. If ever somebody gets your hard drive, he can get every information about you from the drive, no matter where it is hidden.” A shocking incident reported in recent times involves the details of a government contract worth $22 million that were extracted from an old hard drive. When attempts were made to locate the source, it was traced back to Northrop Grumman, one of the military contractors of the country. The drive also held highly classified information about contracts with Homeland Security, NASA, and the U.S. defense intelligence agency. Think about it! If government agencies can become the targets of millions of dollars worth of data breaches, your information is a much easier target. 4. Recycling Lowers Wastage of the Earth’s Resources: Reusing gadgets and recovering reusable materials from them will help reverse some of the wastage of the earth’s resources. Should you check some of the statistics revealed by ThoughtCo., you will learn that the power saved by recycling a cell phone can run a laptop for 44 hours. If all of the 130 million phones annually discarded in the U.S. were recycled, the energy saved could power 24,000 homes for a whole year. Other than gold, silver, and copper, cell phones also contain palladium, platinum, tin, and zinc, all of which are metals that can be used and reused several times over simply by adopting the proper e-waste recycling methods. Responsible e-waste recycling is now more about protecting the environment in your country. The problem has become so huge that you need to take a step back and carefully view the big picture. Saving the earth begins with every citizen who upgrades to a new gadget. Have you REALLY done your bit?

Does Vinegar Harm Gun Bluing?

Gun safety and maintenance are at the forefront of most gun owners’ minds. We want to be able to clean our firearms without worrying about damaging them. If you’ve looked at online forums at any point, you may have seen some people recommending using vinegar in cleaning. Is this safe, though? Well, I’ll explain to you why it’s probably not the best thing to use in this article. There are better alternatives that can clean it without any risk of corroding the metal – especially something like aluminum. Cleaning our Weapons As I mentioned above, if you look at any forums like this one, there is a hot debate on how to properly clean our weapons. A variety of methods are suggested. It’s important to remember that bluing on our guns is a vital part of it. You see, it protects the metal beneath from oxidation, usually known as rust. Besides being ugly, it can negatively impact its integrity of it. If there is already rust, though, you might need to scrape it away. This can remove some of the bluings. How can you clean them, then? Some recommend vinegar or a combination of that and other materials such as peroxide. Unfortunately, this can damage it. Acids and other corrosives probably are not a good idea. What Should We Use Instead? There are a few ways that we can go about this. You are probably wondering what the best rust remover for guns is, so I’ll discuss a few options here. The first thing I will cover is prevention. If you store your firearm in a cool and dry place, it will most likely not oxidize at all. This is a good way to keep this problem from happening in the first place. However, if rust does occur, you can go on to the next methods. You could try a battery charger. For this, though, you will need a few other things. This will probably only work for one made of something like aluminum or copper, as well. Locate some baking soda, a battery charger, a steel rod, and a plastic container. No matter which way you are cleaning, make sure the gun is not loaded. This is for your own safety as well as everyone else around you. You should look in the barrel and double-check, maybe even triple-check, that there is no ammunition within. Next, you might try a traditional cleaning kit. You can get them at most retailers that sell weapons like this. This might be a slightly pricey option, but because the products are designed for this purpose, they are safe. There is a low chance of damaging the bluing. Of course, you could also use steel wool and some oil. If you use a form of lubricating oil before going in with the abrasive surface of the steel wool, you will most likely be able to remove the rust without causing any damage. You need to have a careful and methodical process. As you go about the process of your choice, you will want to keep in mind some essential parts of cleaning your gun. As you disassemble it, you should only do it in the way that the creator of it tells you to. Otherwise, you may be risking your own safety. Wherever you decide to do it, it should not be a closed space. Having proper ventilation is critical so that you do not inhale anything toxic. Some firearms use lead in them or ammunition. Breathing this in is not something you will want to do. If you didn’t know, it is recommended to care for your weapon after each time you use it. Whether you go hunting or to the shooting range, getting rid of the residue is a part of being a responsible owner. What you use for this might vary depending on the type you own. For example, rifle users may want to get a barrel snake. This probably is not necessary for pistols or other smaller barreled guns, though. My recommendation is to do your research on what to use for your specific weapon, and you probably should not use vinegar. Additionals: What is an Airsoft Gun?
