Your Best Source for Laptop Batteries & AC/DC Adapters

The tech world is developing quickly, and so is the laptop power technology. The today’s result of laptop power packs research is a gradual switchover from lithium iron batteries to portable fuel cells.

Media Bay Fuel Cell

We can trace the respected activity of some power source makers and be aware of what we are to have soon. For instance Panasonic’s purpose is to create a methanol fuel cell enabling a laptop to work for 20 hours, but this promise is planned by the company only in two-three years.

The more working hours for cell-phone talk is already offered by Medis Technologies Ltd., it has issued a 1-watt liquid borohydride fuel cell recharger with the above-mentioned potency. But the 24-7 Power Pack when exhausted has to be recycled, not refuelled.

Anyway some analysts do not expect the wide commercialization for fuel cells, the switchover will go a bit at a time. The new technology should be standardized. And nowadays some companies manufacturing laptop power units are moving toward their products other than fuel cells, but enabling enlarge their capacity as well. For instance silver-zinc batteries are expected from Lenovo, and their capacity will be 20-30 per cent higher than that of a conventional lithium ion battery.

Lenovo is on the bazaar with its Dell Latitude C640 Charger (as accepted rumors the accomplished few months). A netbook which is accurate by a chipset Nvidia ION . With this feature, the 12-inch netbook is able to accommodate a reproduction of HD agreeable in a amount about 379 € (in the U.S. it is $ 500 U.S.).

We alpha from the base for compassionate what we’re talking about. ION Nvidia belvedere is an Intel Atom alternation that is accumulated with an Dell Latitude C800 Charger graphics. According to beta analysis the performances are not too top because the video adaptation is alone 1080p, and con playback (Dell Latitude D410 Charger) and Blu-Ray drives aswell plan able-bodied on games. So even if not the top of the range, the breadth able with Atom netbook, absolutely can accomplish a difference.Dell Latitude D400 Charger Particular agenda is that the 1080p video adaptation can be acclimated alone and alone on an alien affectation affiliated to HDMI and not on the aforementioned display, partly because the adviser is based on a built-in 720p.

As you may anamnesis the case with the Dell Inspiron 8000 battery Revolution which was based on the chipset ION Lenovo is a avant-garde in the field, but it absolutely is a abundant artefact for those who wish to yield advantage of a medium-end netbook with 12-inch awning and a carriageable possibilities of multimedia top enough.

The awning resolution is 1280 × 800, the RAM is 1 GB on lath and the Hard Disk 160 GB. It aswell has a agenda clairvoyant 4-in-1 amplification aperture and a 3G. The array of three beef can accord a acceptable accommodation for autonomy.

Lithium-ion batteries, often found in laptop computers, differ from primary lithium batteries, which are often used in cameras. Some newer AA-size batteries are also primary lithium.

While there is no explosion hazard associated with either kind of battery, the Federal Aviation Administration has studied fire hazards associated with both primary and lithium-ion cells, and their extensive research is publicly available. As a result of this research, the FAA no longer allows large, palletized shipments of these batteries to be transported as cargo on passenger aircraft.

The research also shows that an explosion will not result from shorting or damaging either lithium-ion or primary lithium batteries. Both are, however, extremely flammable. Primary lithium batteries cannot be extinguished with firefighting agents normally carried on aircraft, whereas lithium-ion batteries are easily extinguished by most common extinguishing agents, including those carried on board commercial aircraft.

TSA has and will continue to work closely with the FAA on potential aviation safety and security issues, and TSA security officers are thoroughly and continually trained to find explosive threats. TSA does not have plans to change security regulations for electronic devices powered by lithium batteries.

• Keep batteries and equipment with you, or in carry-on baggage – not in your checked baggage! In the cabin, flight crew can better monitor conditions, and have access to the batteries or device if a fire does occur.
• Buy batteries from reputable sources and only use batteries approved for your device – avoid counterfeits! A counterfeit battery is more likely to cause a fire in your equipment – costing you more in the long run, and compromising safety.
• Look for the mark of an independent testing or standards organization, such as Underwriters Laboratories (UL) or International Electrotechnical Commission (IEC).
• Do not carry recalled or damaged batteries on aircraft. Check battery recall information at the manufacturer’s website, or at the Consumer Product Safety Commission.
• Only charge batteries which you are sure are rechargeable! Non-rechargeable batteries are not designed for recharging, and become hazardous if placed in a battery charger. A non-rechargeable battery placed in a charger may overheat or cause damage later.
• Only use a charger compatible with your rechargeable battery – don’t mix and match!
• If original packaging is not available for spare batteries, effectively insulate battery terminals by isolating the batteries from contact with other batteries and metal. Do not permit a loose battery to come in contact with metal objects, such as coins, keys, or jewelry.
• Place each battery in its own protective case, plastic bag, or package, or place tape across the battery‘s contacts to isolate terminals. Isolating terminals prevents short-circuiting.
• Take steps to prevent crushing, puncturing, or putting a high degree of pressure on the battery, as this can cause an internal short-circuit, resulting in overheating.
• If you must carry a battery-powered device in any baggage, package it to prevent inadvertent activation. For instance, you should pack a cordless power tool in a protective case, with a trigger lock engaged. If there is an on-off switch or a safety switch, tape it in the “off” position.

You’ve probably been in this situation. You’re out and about, having a great time and then suddenly notice that you have one bar of power left on your phone. When that last bar starts blinking, it’s a crucial situation. Without your cellphone you can’t get in touch with friends or family, find phone numbers, listen to music, or retrieve urgent information. When your cell phone battery goes dead and you don’t have a regular charger handy, there is a way that you can get a little extra power until you get home.

Instructions

Although new cell phone batteries can have a slight charge when purchased, this is usually from quality control testing—most batteries ship uncharged and require a full day, or at least overnight, charging before use. Thankfully, manufacturers have designed cell phone batteries and battery chargers for quick and easy charging in a “3-cycle” charging process that helps you to condition your batteries to work at the highest possible level of performance.

Instruction

Select a charging method, as you can charge new cell phone batteries–depending on the manufacturer’s preferences or design specs–a wide variety of ways. Put your battery or batteries inside your phone and charge with a direct line AC power supply cord that plugs into your phone and an electrical wall socket; or place the phone in a phone charger; or insert the battery/batteries directly into a battery-only charger.

Charge the batteries using your chosen method. If charging the battery/batteries inside your cell phone, turn the phone off before charging unless otherwise directed by any manufacturer’s instructions. Charge your cell phone for 12 to 24 hours depending on the type of battery your phone uses and/or the manufacturer’s instructions. For example, NiMH (Nickel Metal Hydride) batteries require a longer charging period than Li-ION (Lithium Ion) batteries.

The battery in your laptop is the device that stores and supplies power to your laptop computer. Most laptop batteries in use today are lithium-ion batteries. Lithium-ion batteries are used for laptops due to their efficient energy density. If you have noticed your laptop’s battery is no longer holding a charge, you will have to replace it. It will take about ten minutes to replace the battery in your laptop.

What battery to buy:

Purchase a new compatible laptop battery online or at a computer electronics store. Your laptop’s user manual will list the type of battery currently used in your laptop. You may purchase the same battery or search for a compatible battery of a different brand. If you decide to use a non-factory battery, you must make sure the new battery meets all the charge requirements of your laptop. You must also make sure your new battery will physically fit into the battery chamber. Laptop battery chambers are a very tight fit. Aftermarket batteries will usually list the laptops they are compatible with both in size and charge.

Step 1: Turn off your laptop and remove the power cord. The power cord is the cable that connects from your wall outlet to your laptop.

Step 2: Turn over your laptop and find the battery chamber. The battery chamber will be clearly marked by a battery icon. Take note of the lid removal method once you have found the cover.. Laptop battery chambers are secured by screws or by a latch that can be released with your fingers.

Step 3: Remove the screws to the battery chamber lid or depress the latch and remove the cover with your fingers. You will now be able to see your laptop’s battery. Place the screws in a small cup as you will need them later to replace the cover.

Step 4: Remove the old battery from the battery chamber. Make sure you do not touch the battery contacts in the laptop with your fingers. Your fingers hold oils that can corrupt the connection between the battery and your laptop.

Step 5: Carefully slide the new battery into your laptop. Make sure the contacts on the battery align with the contacts on your laptop. Replace the battery cover once the battery has been inserted.

Step 6: Reconnect the power cord to your laptop computer. Allow the laptop battery to fully charge. If your laptop does not have a light indicator for a fully charged battery, allow the battery to charge for at least eight hours.

If you want to prolong the battery‘s effective use of time, in addition to the quality of the charger should be guaranteed, the correct charging technique is also essential, because the poor quality of the charger or charging the wrong methods will affect battery life and cycle life The following is the author of sorting out the charging techniques:

1. Battery factory, manufacturers have carried out active treatment, and conduct a pre-charging, the battery have more than electricity, a friend said rechargeable battery in accordance with the time period of adjustment, standby is still a serious shortage, assuming the battery is indeed the genuine battery, then this case adjustment period should be extended a further 3 to 5 times fully charge and discharge.

2. If you buy a new phone battery is a lithium-ion, then the first 3 to 5 times a charge commonly referred to as the adjustment period, more than 14 hours should be sufficient to ensure the full activation of lithium-ion activity. Lithium ion batteries have no memory effect, but there is a strong inert, should be fully activated in order to ensure the future use to achieve the best performance.

3. Some automated intelligent rapid charger when the lights change, said only 90 percent full.Charger will automatically change with the slow charging the battery is full. Best use of the battery is full, otherwise it will reduce the use of time.

4. Before charging, lithium batteries do not need special discharge, discharge improper battery will be damaged. Charging as much as possible to slow enrich my knowledge, to reduce the fast charge mode; time should not exceed 24 hours. After three to five times the battery fully charge and discharge cycles of its internal chemical substance will be all “activated” to achieve the best results.

5. Please use the original or the reputation of a good brand chargers, lithium batteries use lithium battery charger, and follow the instructions, otherwise it will damage the battery, or even dangerous.

6. Many users are often in charge Shihai the phone open, in fact, it will hurt the mobile phone life very easily, because in the charging process, the mobile phone circuit boards will be fever, at this time if there are external phone, may produce an instant return current, the phone’s internal parts damage.

7. Battery life depends on the number of repeated charge and discharge, it should try to avoid charging the battery is more than power, it will shorten battery life. Phone off more than 7 days, should be the first mobile phone battery is fully discharged, adequate electricity and then use.

8. There cell phone battery self-discharge Ni-MH battery when not in a day by about 1% of the remaining capacity of the discharge, lithium batteries a day by 0.2% to 0.3% of the discharge.Charging the battery, try to use a dedicated outlet, do not share the charger socket with TV and other appliances.

9. Although the mobile phone network coverage area, but the phone off when charging the phone has been unable to accept and make calls. At this point, you can use the phone did not pass transfer function, will be transferred to the side of the fixed-mobile phone to prevent calls lost, this method for the mobile phone network coverage area or signal is weak and can not be connected when they apply.

10. Do not expose the battery in hot or cold, like a dog day, not the phone in the car, stood in the scorching sun exposure; or get air-conditioned room, where on the air blowing straight. When charging, the battery a little heat is normal, but can not make it hot Jinshou “suffering.” To avoid this from happening, it is best at room temperature for charging, and do not cover anything on the phone.

11. Nickel-cadmium (N iCd) before the battery must ensure that the battery is completely discharged, then charge must ensure that the battery is fully charged.

12. If the phone battery is too long without use, it is best to apply to cell phone service departments to make a living process, you can own a DC barostat, adjust voltage of 5 ~ 6V, current 500 ~ 600mA reverse battery connector . Note that touch open up to repeat three times, after such treatment, then the original charger “adjustment” charge.

13. Charging is not longer, and there is no protection circuit of the battery is full charge should be stopped immediately, otherwise the battery overheating due to heat or impact performance.

14. Dedicated lithium-ion battery charger must be selected, otherwise it may not reach saturation, impact on its performance. After charging, the charger should avoid placing more than 12 hours or more, long-term without the battery and the phone should be separated.

Cell phones run on batteries that are recharged through connection to an electrical socket when they are drained of power. Cell phone batteries are square, flat, installed in the back of the device and covered by a protective cover. Since cell phones are left on for most of the day, the battery is in almost constant use. Cell phone batteries do not last forever and it is important to identify the warning signs that indicate a battery needs to be replaced.
