A deep-cycle battery delivers 100–200 cycles

July 03 [Wed], 2013, 10:42
A lead acid battery goes through three life phases, called formatting, peak and decline (Figure 1). In the formatting phase, try to imagine sponge-like lead plates that are being exposed to a liquid. Exercising the plates allows 607763-001 high quality the absorption of more liquid, much like squeezing and releasing a sponge. This enables the electrolyte to better fill the usable areas, an exercise that increases the capacity.

Formatting is most important for deep-cycle batteries and requires 20 to 50 full cycles to reach peak capacity. Field usage achieves this. There is no need to apply added cycles for the sake of priming; however, manufacturers recommend to go easy

A deep-cycle battery delivers 100–200 cycles before it starts the gradual decline. Replacement should occur when the capacity drops to 70 or 80 percent. Some applications allow lower capacity thresholds but the time for retirement should not fall below 50 percent because the aging occurs rapidly once the battery is past its prime. Apply a fully saturated charge of 14 to 16 hours. Operating at moderate temperatures assure the longest service times. If at all possible, avoid deep discharges; charge more often.

The primary reason for the relatively short cycle life of a lead acid battery is depletion of the active material. According to the 2010 BCI Failure Modes Study,* plate/grid-related breakdown has increased from 30 percent five probook 4510s high quality years ago to 39 percent. The report does not give reasons for the increased wear-and-tear, other than to assume that higher demands of starter batteries in modern cars induce added stress.

While the depletion of the active material is well understood and can be calculated, a lead acid battery suffers from other infirmities long before plate- and grid-deterioration sound the death knell. The following articles address the most common problems that develop with use and time and what battery users can do to minimize the effect.

Toppan has now developed a new battery-free RFID

May 14 [Tue], 2013, 11:29
There are an increasing number of initiatives using smart cards and IC tags to enhance the efficiency of logistics management and improve customer service in the distribution and amusement industries. As an evolution U330 brightof such applications, there is increasing demand for devices with display functions that allow information on the smart card or IC tag to be confirmed on the spot.

Devices with display functions have existed for some time but most of these products included a battery within the device in order to provide power to change and maintain the information displayed. This presented a challenge because maintenance was needed every time the battery was changed.

In February 2012, Toppan Printing developed a battery-free contactless smart card with a display function that featured a segment type (*4) electronic paper display. This card had similar dimensions and thickness to previous cards but had a system that could display the information in the contactless smart card using only the power supply from the reader/writer.

Toppan has now developed a new battery-free RFID product with a dot-matrix electronic paper display that can display text and images. With this new product, the original electronic paper control and antenna technologies that were created during the development of the battery-free contactless smart card U350 brightwith a segment-type display have been further advanced.

With the addition of a newly developed low-power consumption circuit design technology for contactless power supply, it has become possible to drive the display with general reader/writers even though it is a dot-matrix type with high power consumption. This means that use has become possible for numerous reader/writers in a wide range of industries.

Mains on the screen without the need for a battery

May 14 [Tue], 2013, 11:26
Toppan Printing Co., Ltd. (hereafter Toppan Printing; head office: Chiyoda Ward, Tokyo; President & Representative Director: Shingo Kaneko) has developed an RFID (*1) device that is compliant with the ISO/IEC15693 (*2) communication standard and can display information on an IC chip in text and images U150 bright without the need for a battery. Sample shipments are scheduled to begin in spring 2013 with use envisaged for applications where text and images such as QR codes on an IC chip need to be displayed for confirmation, such as management of processes or status in factories and hospitals.

This is an RFID device that has a 2.7 inch dot-matrix (*3) electronic paper display and enables the display to be changed without the use of a battery. A battery is not required because information can be read, written and displayed using only the power supply from the reader/writer. Since electronic paper is used for the display section, information displayed remains on the screen without the need for a battery.

The method of communication is compliant with ISO/IEC 15693, which is widely used in the field of RFID. Due to the use of a low-power consumption circuit developed by Toppan, it has become possible to operate this device U160 bright with general reader/writers even though the display is a dot-matrix type, which consumes a lot of power.

This product will be displayed in the Toppan booths at CARTES 2012, which will be held from November 6 to 8, 2012 in Paris, France, and at Messe Nagoya 2012, which will be held from November 7 to 10, 2012 at the Port Messe Nagoya exhibition center in Nagoya, Japan.

Inspect both batteries before connecting booster cables

April 02 [Tue], 2013, 12:32
No one wants to think of the moment when they may have to deal with jump-starting a car battery, but we all know it can happen. Here arecompatible A1189 instructions for how to do it safely and successfully.
Safe Handling of Battery Acid

Battery acid, or electrolyte, is a solution of sulfuric acid and water that can destroy clothing and burn the skin. Use extreme caution when handling electrolyte and keep an acid neutralizing solution—such as baking soda or household ammonia mixed with water—readily available. When handling battery acid:

Always wear proper eye, face and hand protection.
If the electrolyte is splashed into an eye, immediately force the eye open and flood it with clean, cool water for at least 15 minutes. Get prompt medical attention.
If electrolyte is taken internally, drink large quantities of water or milk. DO NOT induce vomiting. Call a physician immediately.
Neutralize with baking soda any electrolyte that spills on a vehicle or in the work area. After neutralizing, rinse contaminated area clean with water.
To prepare electrolyte of a desired specific gravity, always pour the concentrated acid slowly into the water; DO NOT pour water into the acid. Always stir the water while adding small amounts of acid. If noticeable heat develops, allow the solution to cool before continuing to add acid.

Safe Booster Cable Operation

When jump starting a vehicle, always wear proper eye protection and never lean over the battery.
Inspect both batteries before connecting booster cables. Do not jump start a damaged battery.
Be sure vent caps are tight and level.
Make certain that the vehicles arecompatible VGP-BPS13/Q not touching and both ignition switches are turned to the OFF position.
Refer to the vehicle owners' manual for other specific information.

The latest electronic chargers mostly make us the IUI charge profile

April 02 [Tue], 2013, 12:19
For best battery life, i.e. greatest number of charge/discharge cycles and years service most battery manufacturers recommend that you should aim to recharge the batteries when they have reached around 50% discharge. Thiscompatible A1309 level of discharge, of course, must be measured according to the rate at which the batter is discharged, which as w have already seen, varies the available total capacity of the battery.

In addition, some battery manufacturers specify that best life will be achieved only if the batteries are discharged sufficiently for a 4 hour bulk charge to take place before the batteries are fully recharged.

A reasonable rule of thumb is that you should aim to charge the batteries only when they are between 70% and 40% discharged. If you charge them then they are only lightly discharged i.e. less than 40% you will end up boiling them unnecessarily which wastes energy in the form of heat and gassed off hydrogen and in turn shortens the life of the batteries.

In effect the batteries are being overcharged which can cause degradation and buckling of the plates. In the process some active material is forced off the plates and drops down to the bottom of the battery. If this occurs frequently the eventual result is a build up of a bridge between the plates which in turn can cause a possible short across the plates. This situation leads to the destruction of a cell which then reduces the capacity of the battery.

To confuse matters further, a battery will operate at its most efficient the deeper it is discharged, up to around 75%. The bulk phase of the charge cycle is the most efficient and is proportionately longer the deeper the discharge.

There are many battery chargers available. Today, manufacturers supply automatic chargers which are supposed to ensure optimum battery life. there are numerous charge profiles available and now, with the advent of the electronic switch mode chargers, it is possible to have a fully programmable charger on board your car capable of charging almost any type of battery.

Lead acid batteries must be charged carefully. If the charge is too violent and uncontrolled the batteries can overheat and cause thermal run-away which can result in a possible explosion.

Too gently charging will take too long to get the batteries fully charged with the result that the batteries will end up being used in an under charged state eventually leading to premature failure due to sulphation.

The latest electronic chargers mostly make us the IUI charge profile for standard flooded lead acid batteries. This means that the current drawn by the batteries is allowed to flow at a constant (I) rate while the voltage is allowed to rise of its own accord, which it will do as the battery starts to be charged up. This first part of the charging cycle is known as the bulk charge phase.

When a preset voltage has been reached, normally the voltage at which the batteries just start to gas, the charger will switch into the constant voltage (U) phase and the current drawn by the battery will gradually drop until it hits another preset level. This second part of the cycle is really the finish charge compatible A1245where the battery just topped up to the brim very carefully at a much gently diminishing rate. Finally the charger will switch again into the constant current mode (I) and the voltage is allowed to rise again, up to a new higher preset limit, in order to achieve a successful equalization charge.

The trickle charger will also work on your car battery

January 29 [Tue], 2013, 14:38
To learn the proper maximum charging rate for your battery, look at the alphanumeric code printed across the case of the battery and you will usually find its Amp/Hour rating. If it's not obvious, check your owners manual. The proper trickle-charging rate for a motorcycle battery is one-tenth of the A/H rating for as cheap Inspiron 1720 battery long as 10 hours, depending on how discharged it is. Charging faster than 2.02.5 amps causes overheating which can warp and even melt the battery case if ignored.

High-rate charging also speeds up internal corrosion, and its visible sign is sediment buildup under the cells, which if it reaches high enough, will also permanently short out the battery. Too high a charging rate can also result in a battery that does not hold a charge because too-rapid transformation of the lead sulfate may actually trap sulfate under a surface coating of rejuvenated lead, producing a battery that can test okay but fails quickly. Thankfully, this last effect can be reversed with a very slow charge of no more than 1/20 (yes, that's one-twentieth) of rated capacity for 25 to 30 hours.

Therefore, because we really don't want a powerful charger, a good battery charger for most purposes is the inexpensive low-output type. Typically selling for around $20, the so-called "trickle chargers" usually produce no more than 1.2 amps. They often incorporate a solid-state feedback circuit that will taper the charge down to even lower levels as the battery voltage comes back up, preventing overcharging. Most convenient are the quick-connect type that provide a pigtail connector that can be permanently attached to the battery. The trickle charger will also work on your car battery, but even more slowly, and produces the same battery-friendly results.

Both the taper-rate and trickle charger supply only a fixed voltage. However, the lead-antimony battery should be charged at 1415 volts, but the lead-calcium type needs l516 volts to reach full charge. What's the voltage cheap XPS 14 battery of your charger? Does it match your battery type?

Constant current chargers like the Optimate or Battery Tender brands are called smart chargers because they can vary the charging voltage to keep current constant and charge a battery much more quickly. We'll cover their other advantages in a future article.

The person has committed a battery as well as an assault

December 12 [Wed], 2012, 14:36
Battery is a general intent offense. This means that the actor need not intend the specific harm that will result from the unwanted contact, but only to commit an act of unwanted contact. This also means that gross negligence orrn873 X120e even recklessness may provide the required intent or (in criminal matters) mens rea to find a battery.

The doctrine of transferred intent is also applicable. If one person intends to strike another, but the person moves out of the way to avoid being struck, causing the blow to hit a third person, both an assault (against the second person) and a battery (against the third person) have occurred, in both criminal and civil law.

This is important in the distinction between a battery and an assault. A battery involves actual contact. An assault is, in actuality, an incomplete battery; a person commits an assault if he or she intentionally places a person in apprehension of an impending battery. Conversely, if a persons intended only an assault (to cause apprehension of an imminent battery), and harmful or offensive contact actually occurs, the person has committed a battery as well as an assault.

This is also important in distinguishing accidental conduct. If a person violently slams into a fellow passenger on a moving public bus, there is no liability. But if, on the same public bus, there is only the slightest intentional touching of another, which is harmful or offensive and also non-consensual (such as reachingbattery for X130e out and touching a woman's thigh), a battery has occurred.

Conversely, if there was only an intended assault, as in a person gesturing toward another in a menacing manner, and the person trips and actually crashes into the other person, both an assault and battery have occurred.

The good news about Going Green is that lowering your carbon footprint

December 12 [Wed], 2012, 14:31
A few days ago we reported on the issue of standby power–that our homes and workplaces are populated with electronics that often consume energy even when they’ve been turned off. Nationally,such secretive parasites add 5-10% to our total electrical consumption.At the global level,one of the biggestThinkPad T420s laptop battery culprits are cell phone chargers.Without diving into a nerdy discussion of electrical engineering,most chargers use essentially the same amount of power regardless of whether they’re recharging batteries or sitting idle.


In fact,the lion’s share of a mobile battery carbon footprint lies not in the energy required to charge its battery,but in the endless hours that its charger will spend plugged into an outlet doing nothing.A small portion of consumers are fairly dedicated about removing their chargers from the outlet when it’s done,but most are simply unaware of the problem.Then there are those not unlike myself,who,however well intentioned or conservation-savvy,have occasionally forgotten to unplug said cell phone charger only to realize their absentmindedness many days,and watts,later.

Whatever group of consumer you fall in,there’s good news as AT&T’s ZERO smart charger has announced that it will be offering a smart charger for its US customers at “dumb” charger prices.This is particularly good news for iPhone and Blackberry owners seeking to keep their carbon footprint as trim as possible.If the whole issue of fretting over cell phone chargers sounds trivial,keep in mind that Original X100ethere are an estimated 4.6 billion cell phones in use around the globe.

The good news about Going Green is that lowering your carbon footprint = saving money,not the other way around.Just like the smart chargers, our expertise lies in delivering to you the necessary information to intelligently lower your energy usage (and without having to give up your car or electricity.)

This new improved battery lasts 10 times longer than ordinary batteries

October 22 [Mon], 2012, 17:32
Summed up in one word, the answer is weight. Those who design these devices are faced with difficult decisions. How can we make the device have long operating time, yet keep the weight down? A bigger battery will contain more energy to make it last longer, but will the market stand for the added weight? What isoriginal rn873 HSTNN-C51C our competition doing? If the competition has switched to a more exotic type of battery, Lithium-ion or Nickel-metal Hydride, then they are forcing the customer to use more expensive replacement batteries, which may not be easily replaced.

A specially-designed charger would have to be included with the product for these specialty batteries, and that drives up the selling price of the product even more. And these chargers are not usually interchangeable with any chargers the customer may already have.

The power supplied by the batteries to your digital camera, your MP3 player, or your radio, multiplied by the time the power flows, equals a certain number of Watt-hours. Are you familiar with the electric utility meter on your house or apartment that registers the number of Kilowatt-hours you and your family use? The utility then bills you for the quantity of energy (kilowatt-hours) that you use. Batteries don't store power, they store energy. Did you know that? When you buy a battery you are paying for the energy it contains, and at a premium price if the technology behind the battery is new and therefore it is lighter than expected.

The amount of energy stored in a given battery depends, not only upon its weight and volume, but upon the materials and construction of the battery. For instance, you can count on any brand of alkaline battery to have within it about 4 times the energy of the old-fashioned carbon-zinc battery. Those carbon-zinc12 cells 448007-001are still around in packages labeled "heavy duty" or "transistor power". (Beware when you are buying batteries -- look for the word "alkaline" on the package.)

In high-drain applications such as toys, cameras, and CD players, carbon-zinc batteries will not be able to provide that one-quarter energy of alkaline batteries of similar size. They will yield only a little more than a quarter of that quarter, or roughly 10% of the alkaline's energy. This figure is frequently quoted when comparisons are made in battery commercials on TV. "This new improved battery lasts 10 times longer than ordinary batteries." Guess what kind of ordinary battery they are comparing it to!

Average battery life has become shorter as energy requirements have increased

October 22 [Mon], 2012, 17:24
If you have done any research on how batteries work or what you should look for when selecting a battery, you are probably buried in information, some of which is conflicting. At BatteryStuff, we aim to clear that up a bit.You have most likely heard the term K.I.S.S. (Keep It Simple, Stupid). I am going to attempt to explain how lead acid replacement battery for HSTNN-Q34C work and what they need without burying you with a bunch of needless technical data.

I have found that battery data will vary somewhat from manufacturer to manufacturer, so I will do my best to boil that data down. This means I may generalize a bit, while staying true to purpose.

The commercial use of the lead acid battery is over 100 years old. The same chemical principal that is being used to store energy is basicly the same as our Great Grandparents may have used.

If you can grasp the basics you will have fewer battery problems and will gain greater battery performance, reliability, and longevity. I suggest you read the entire tutorial, however I have indexed all the information for a quick read and easy reference.

A battery is like a piggy bank. If you keep taking out and putting nothing back you soon will have nothing. Present day chassis battery power requirements are huge. Consider today’s vehicle and all the electrical devices that must be supplied. All these electronics require a source of reliable power, and poor battery condition can cause expensive electronic component failure. Did you know that the average auto has 11 pounds of wire in the electrical system? Look at RVs and boats with all the electrical gadgets that require power.

It was not long ago when trailers or motor homes had only a single 12-volt house battery. Today it is standard to have two or more housern873 HSTNN-C17Cpowering inverters up to 4000 watts.

Average battery life has become shorter as energy requirements have increased. Life span depends on usage; 6 months to 48 months, yet only 30% of all batteries actually reach the 48-month mark. You can extend your battery life by hooking it up to a solar charger during the off months.
