Advantages and Disadvantages of the Lithium-Ion Battery

The lithium-ion battery is one of the most popular choices for consumer and portable electronics. The high performance and fast recharge cycle also makes is a great choice for automobile, aerospace and military applications. Here are a few of the basic advantages of using the lithium-ion battery:

Compact size

The lithium-ion battery is smaller and lighter than most other types of rechargeable batteries in the market. The compact size makes is a popular choice for a wide range of electronic gadgets.

High-energy density

The high energy density of this type of battery makes it a very favorable choice compared to the alternatives. This means the battery has the ability to provide a lot of power without being large in size. The high energy is great for power-hungry gadgets like tablets, smartphones and laptops.

Low self-discharge

The lithium-ion battery has low self-discharge rate, which is estimated at about 1.5% per month. The slow rate of discharge means the battery has a long shelf life and the potential to be recharged and used a lot more often than other options. For instance, the metal-nickel hydride battery has a much faster self-discharge rate of about 20% per month.

Fast charge cycle

The fast charge cycle is a further reason for its great popularity in day-to-day electronics like phones and tables. The charge time is latterly a fraction of the alternative choices.

Long lifespan

The lithium-ion battery has the ability to complete hundreds of charge and discharge cycles. Over the battery’s lifespan, it is likely to see a reduction in capacity. For instance, after a total of 1000 cycles there is the risk of losing up to 30% of its capacity. However, the loss of capacity varies with the type and quality of the battery. The most advanced lithium-ion battery is more likely to hold full capacity until about 5000 charge-discharge cycles are complete.

Are there any disadvantages

In addition to the wide-ranging advantages of the lithium-ion battery, there are also a few disadvantages to note. A common issue is likely to relate to the cost. This type of battery is nearly 40% more expensive than its closest alternatives. A reason for the higher cost is the need to combine the battery with on-board computer circuitry to help control issues with current and voltage. Also, heat can be an issue. Any battery left or used in a high temperature environment will find the performance and quality of battery degrades faster.

When Laptop Chargers Go Bad

In order to keep your laptop up and running in good condition, it is important to treat all pieces with care to instill that it operates for a longer time frame. This not only includes your laptop, but also the laptop charger. A laptop charger is more than just a cord to plug-in the wall but instead is a necessity to keep the computer and the battery life up so that your laptop will be charged and ready to use for work or play as needed.

Most laptop computers have two power sources: One is the battery and one is the electrical cord.

The electrical cord, however, is essential to providing power to the battery. Once the laptop is unplugged, the battery will start to wear down. The older the battery and laptop, the shorter the battery life is. In order to keep your computer from dying in the middle of a project or activity, a person must use their charger to charge the battery up too. A laptop charger typically also will operate a laptop even if the battery pack is removed. A charger will provide power to the laptop, it just will not recharge the battery if it is removed.

Typically a laptop charger consists of a cord that runs from a wall outlet to a power box and from the power box another cord runs that can be plugged into the back or side of the laptop computer. Typically most charger devices have power light indicators that tell if it is properly plugged in and working. The laptop desktop will typically have an icon that shows the battery level and will also show if it is plugged in to a charger, therefore increasing the battery life again.

If a laptop charger is broken or fries out after a long extended period of time, it is imperative to find a back up immediately. It will not take long for your battery to run down on your laptop, typically a few hours. Once the computer dies, there is no turning it back on without a laptop charger. Sometimes charger devices eventually just give out or something happens where the electrical cords are somehow broken inside the protective coating.

Depending on your type of laptop, it is essential to look around to find one that is compatible to your computer. You may have to contact your computer’s manufacturing brand to see if they have chargers that can be used with your computer. Otherwise, it is usually easier to conduct an online search to find one that is specific to your laptop brand and model. Depending on the chargers and the retailer, these can usually be found inexpensively. Sometimes, it is even nice to have a charger on hand just in case as a back up. When a laptop charger goes bad, it is not the end of the world unless you are someone who is constantly using your laptop computer to go online, or complete work or educational tasks and that is when you will wish you had a back up laptop charger.

Reasons Why You Need To See A Nail Spa Expert

For women, it takes a lot of effort to stay beautiful and confident all day, every single day. This is why they treat nail spas as their best friends when it comes to feeling beautiful, empowered and looking fab. Having a manicure and pedicure regularly is like having a breath of fresh air. It only takes one full session at a nearby beauty and health spa to realize that it truly pays to pay attention to your nails. Making your hands and feet look pretty by investing in professional nail care and pampering can go a long way – in terms of helping you achieve a more put-together look, let go of some of the worries of the day and improve your overall health and wellness. Below are some of the benefits you’ll get:

1. Receive no less than professional service and attention. DIY mani-pedi can be time-consuming and may lead to disastrous results. Like a bad haircut, it can sometimes need a long time to correct those amateur errors (hello, misshapen, too-short nails). Going to a trusted nail spa saves you from all the hassle and the pain, time and money wasted on products. Highly trained nail technicians will assist you and ensure the results will be nothing but spectacular.

2. Ensure your nails are always in top health. A total nail care experience will include making sure your nails are thoroughly clean, thus preventing the growth of bacteria and foot odour. Services also include a massage which keeps your hands and feet moisturized, improves blood circulation, and loosens knots and tense, tired muscles. Professional manicures and pedicures also prevent infections caused by ingrown nails resulting from wrong clipping and cleaning practices. Moreover, going to nail care experts regularly will help detect problems early and thus prevent serious and costly complications.

3. Get a change to de-stress. Regular clients consider their favourite nail spa as their temporary escape from the worries of the world. It’s refreshing to have someone take care of you for a change, allowing you to recharge your mind and body. Some also like to schedule spa dates with their friends so they can spend fun, quality time while getting primped and pampered.

4. Save time and money. Leading spas usually offer a wide range of body and beauty treatments aside from nail care. Thus, savvy clients often look for spa deals before booking their appointment, so they can enjoy not just nail services but also other treatments such as facials, waxing or body contouring. After such a relaxing day and getting pro care from top to toe, you’ll leave the spa refreshed, more beautiful, more confident and ready to take over the world once again.

Which Mattress – Sealy Posturepedic, Simmons Beautyrest Or Serta Perfect Sleeper?

Most of the mattress retail stores today carry mattresses from Sealy, Simmons and Serta. Each mattress brand has their own specific mattress product they are most proud of. There is the Sealy posturepedic line, the Beautyrest line from Simmons and the Perfect Sleep from Serta. So which one is really better?

Basically, these three are good brands. However, we can also say that nothing is ever absolute in the mattress industry. A good and reputable brand can still fail you. Some lesser known brands can wow you and vice versa. That basically depends on your comfort needs. Sometimes too, it relies on the manufacturing methods of the company as this will decide whether their mattresses are reliable or not.

If you are after the total package, comfort, support and durability, we will find out if these brands can really provide those benefits you have been looking for.

Sealy Posturepedic
This line can offer you various levels of firmness for your ultimate needs. If you have a need for a plush mattress, they have such a mattress for you, if you want a firmer mattress, they can also provide that for you. You have a lot of options to choose from.

Basically, this mattress line aims of making 4 hours of sleep feel like 6 or 8 hours. Most consumers like the products from Sealy with them saying this is the most comfortable mattress they have ever had. One plus point for Sealy is their customer service. They have quite a reliable customer service compared to other companies.

Simmons Beautyrest
This one also offers a wide range of mattress choices. But unlike Sealy that mostly provides foam mattresses, Simmons concentrate mostly on innerspring mattresses as this is their area of expertise. They have just combined this with visco foam technology for those who want a firmer support to their body.

Simmons is a good choice if you want to combine plush comfort with firm comfort. They have received some bad feedbacks mainly on mattress sagging. But since they offer a good warranty service, you can make the most out of your purchase.

Serta Perfect Sleeper
This mattress line is a good choice for back ache sufferers too. This can be considered highly reliable because even Consumers Digest has deemed this a reliable brand. Most of those who have used this like how comfortable it is. Some just reported bad customer service for this company. But otherwise, their products are worth buying.

The INFJ Marketing Profile – Intuitive/Feeling/Judging Introverts As Marketers

Few marketing coaches and experts consider personality when giving marketing advice. Such and such a technique is the hot thing, or it’s worked for “everyone” – and therefore you should pick it up and run with it, they advise, even if you feel uneasy, fearful or contemptuous of it. Time and time again, I’ve seen business owners and entrepreneurs dutifully try to execute the advice only to do it badly, half-heartedly or with their finger pinching their nose. Others receiving the advice promise to get right on it but delay, delay, delay until the uncomfortable recommendations slip quietly off their to-do list.

My perspective is different. If you feel that specific marketing advice goes against your grain, I encourage you to follow your instincts and ignore that advice. Look for marketing alternatives that feel more comfortable for you and better fit your preferences, habits and beliefs. They offer a faster, less stressful route to success.

A good tool for exploring your natural marketing style is the Myers-Briggs personality system. Let’s take a look at how it applies to one of the major introverted personality types. An introvert is someone who energizes and recharges best when alone, while feeling drained by too much social interaction. (In contrast, an extrovert would rather not be alone and feels most alive around other people.)

In the Myers-Briggs type system, the INFJ (Intuitive/Feeling/Judging Introvert) type is a gentle, caring, intuitive individual who values relationships and has endless curiosity about what motivates people. An INFJ tends to act spontaneously rather than with planning, cherishes deeply held spiritual or global ideals, and dreads conflict. For good or for evil, INFJs easily inspire others through their charismatic and sensitive intelligence.

According to introvert watchers, some well-known INFJs are Jimmy Carter, Oprah Winfrey, Jerry Seinfeld, Eleanor Roosevelt, Billy Crystal, Carl Jung, Bob Dylan, Martin Luther King, Jr., Adolf Hitler, Shirley MacLaine, Mother Teresa, Nelson Mandela and Mulan (the Disney Princess).

If a Myers-Briggs test indicates that you are an INFJ, then you will probably feel very good about marketing methods like these:

· Creating imaginative symbols, logos or images that crystallize your message or method of working

· Crafting visually interesting and verbally resonant advertising

· Incorporating your ideals into everyday business, such as through “green” initiatives

· Using your visionary thinking to issue and publicize predictions for your industry

· Leveraging key relationships to create leadership or publicity opportunities

· Offering insightful advice through a Q&A blog, column or radio/TV/video show

· Rallying your industry to a work-related, somewhat controversial cause

As an INFJ, you don’t normally seek out the limelight, but you don’t object when others nominate you for “___er of the Year” honors. With your great attunement to other people, you find it hard to set limits when clients need your help, and you may need to take special steps to prevent burnout. Avoid tasks or positions requiring great attention to detail. Also avoid roles where you might have to testify in court or defend your position to skeptics, since you usually come to conclusions without direct consideration of evidence. Choose employees, clients and project partners carefully so as to minimize conflicts. Be respectful of those who don’t share your commitments.

Above all, do not pretend to be or act like a passionless professional, because as an INFJ, that is most definitely not you! When you use the ideas above to incorporate your intense caring about people and the world into your marketing outreach, you will attract clients who share and respect your instinctive, deeply felt concerns – and are thrilled to be working with you.
