Some common sense about Rechargeable battery
What is the cycle life of rechargeable battery?
When a latitude D820 battery experiences a charge and discharge, we call a cycle or a period. In the stated charge and discharge principles and the capacity decline before a stated standard, the total cycles it can undergo called rechargeable battery cycle life.
What is rechargeable battery self discharge?
Primary Dell CF623 battery or full charged secondary battery, when put aside for a period, it is capacity will decline or lose, this phenomenon calls self discharge that is electricity flee away. It is decided by the inner electro-chemistry system, similar to water leakage from pond or reservoir.
What is battery inner impedance?
Battery impedance is the resistance when the current flow through an operating cell, in general the internal resistance is included both d.c. and a.c. resistance. For the rechargeable 40Y6795 battery cell resistance is small and electrode is easy to be polarized along with producing a polarization resistance while measure d.c. resistance, the accurate value can't be measured.
What is the memory effect?
Memory effect only happens on Ni-Cd batteries. As in traditional technology a Ni-Cd battery's negative is agglomeration with thick Ni crystal, if Ni-Cd batteries are recharged before they have been fully discharged, Ni crystal easily gathers to form agglomeration, which makes the primary discharge platform come into being. The HP HSTNN-LB31 battery stores the platform, which will be considered as the end of discharge for the next cycle even though the capacity decides that the battery can be discharged to a lower platform. The battery will store this process in its memory so during the next discharge, the battery only remembers this reduced capacity. Similarly any further incomplete discharge in each use will aggravate the effect makes lower capacity. The effect there are two methods to remove the effect: firstly deep discharge at trickle current (i.e. 0.1C to 0V), secondly several cycles at high currents (e.g. 1C).
What is the ambient temperature affects the battery performance?Low temperatures (e.g. -15?) will obviously reduce Ni-Cd and Ni-MH Apple A1175 battery discharge rate. At -20? electrolyte is at its freezing point, charge speed will greatly slow down. At low temperature (under -15?) charge will raise the internal gas pressure and probably unseal the safety vent. Ambient temperature of 5?to 30? is the best range to get effective charge. Generally with temperature rising charge efficiency will become higher. But when the temperature rises to 45? or higher, the materials performance in the battery will be degenerated and battery service life will be shorten greatly.
What is the Over charge affects the battery performance?
The continual charge action after fully charged with certain charge approach is overcharge. the positive capacity is higher than the negative on design, the generated oxygen in positive can composite, through separator, with Cd generated in negative. In general condition the internal pressure will not rise obviously, but if the IBM thinkpad T43 battery charge current is so heavy or the charge time is so long, and the generated oxygen can not be used up in time, there will be some quality defect risen such as internal pressure rising, battery distortion, leakage and so on. Meanwhile its performance will decline.
What is the Over discharge affects the battery performance?
If a cell's voltage reaches a designed value, that means the battery has discharge the stored capacity, but still the discharge action is continual, over-discharge will cause. Commonly the end voltage can be identified through discharge current, for example the end voltage is set at Laptop battery 1.0V/cell as discharged at 0.2C-2C, and 0.8V/cell at 3C or more, e.g. 5C or 10C. Over discharge may cause disaster, especially at heavy current or repeated over discharge. Commonly over discharge can make cell inner pressure raise, and the reversibility of activity materials both in positive and negative will be damaged. Even by charge only part can recover and the capacity is reduced obviously.
What is the short circuit affects the battery performance?
Any kinds of conductive material being bridged with the external terminals of a battery will result in short circuit. Based on the Discount laptop batteries system, a short circuit may have serious consequences, e.g. rising electrolyte temperature or building up internal gas pressure. If the internal gas pressure value exceeds the limitation of cell cap endurances, the electrolyte will leak, which will damage battery greatly. If safe vent fails to respond, even explosion will occur. Therefore don't short circuit.

This blog is for all Americans that are proud to be American. It is for all Americans that are proud of their different cultural heritages. It is for any American, be they Republican, Democrat, Independent, or somewhere in between, that still loves this country with all their heart and wishes we would, as a society, get back to plain, basic common sense.
Feel free to say what you want when you respond. I only ask that you do not use profanities.
You don't have to agree with me and I don't have to agree with you.
The point of this blog is that hopefully Americans will once again stand up and say, "I am an American. I am proud of that fact. And I believe in common sense."
I'll start......................
How come everybody wants to sue everybody else because they don't like what that person has to say? In this country we have freedom of speech. That means that any idiot in this country can say any idiotic thing that they please without fear of retribution of any kind from any governmental agency, and so can I. The only limitation on this would be, of course, when someone says something completely false and that falsehood causes substantial and/or irreparable damage.
Case in point: Dog the Bounty Hunter. Were the statements that he made to his son about his American African girlfriend racist? Absolutely. Should the station that aired Dog the Bounty Hunter's show pulled the show off the air? Absolutely not.
Duane Chapman (Dog) has the right to say and think any ignorant thing he wishes. While I abhor racism, the fact is that Mr. Chapman did not state those hated words at any time during his television show, nor did he state them to any of the people that he was arresting. He did his job and he did it in the correct manner. Therefore, the television station should not have taken his job away. The conversation that was aired so publicly was a private matter that was sold for money to the public. If the public had issue with those words, and I can most certainly understand why they would, then let the public decide whether or not to watch this mans television show.
Some people have gone so far as to state that there is no way Mr. Chapman could be a racist and a Christian at the same time? Really...........? So, other than Jesus Christ, who is the last 'perfect' Christian that any of us has met? Christians are not perfect, in fact most are far from perfect. They are merely human beings that have decided to have a relationship with Jesus Christ. That relationship does not demand perfection. Only our excellence, our personal best that we can give at that moment in our lives. If Mr. Chapman is truly a Christian, and seriously, none of us know the answer to that question, then obviously the area of racism is something he needs to work on.
At the end of the day, however, his actions were done in private, not on the job, and therefore the television station was wrong to pull the show. How many of us would be out of a job if our employers used all of the ignorant mistakes we all make in our private lives against us in our professional lives?
And please, before you send me a tremendous amount of comments that it is African American, not American African............no it was not a typo. If you were born in this country, you are an American first. Then you list your culture. An example of this would be my own children......they were born in this country and they are of Mexican heritage. Therefore, my children are American Mexican. Had they been born in Mexico and had American heritage, then they would be Mexican American.
So that's the first blog of How Come and Why Not? What do you, common sense Americans, have to say about it?
The Kiwi bird is a native of New Zealand and endemic to that island nation. That means it does not live anywhere else in the world, except in zoos. I first wrote about it at my bird blog and the interest from my readers has motivated me to look further into these cute little characters.
Their sense of smell is heightened. Cool. These flightless birds with almost NO wings have nostrils at the END of their bill and use their super olfactory sense to find food in the leaf litter and soil. According to the SanDiego Zoo, where I observed them in a special nocturnal exhibit, when Kiwi Birds are frightened they hide. That is to be expected, but they often hide in burrows, like their nests and stick out their bills to sniff the air nearby to decide if the coast is clear and it is safe to come out.
These special birds are full of surprises.

Obituary of the late Mr. Common Sense
Today we mourn the passing of a beloved old friend, Common Sense, who has been with us for many years. No one knows for sure how old he was, since his birth records were long ago lost in bureaucratic red tape. He will be remembered as having cultivated such valuable lessons as: Knowing when to come in out of the rain; Why the early bird gets the worm; Life isn't always fair; and Maybe it was my fault.
Common Sense lived by simple, sound financial policies (don't spend more than you can earn) and reliable strategies (adults, not children, are in charge).
His health began to deteriorate rapidly when well-intentioned but overbearing regulations were set in place. Reports of a 6 -year- old boy charged with sexual harassment for kissing a classmate; teens suspended from school for using mouthwash after lunch; and a teacher fired for reprimanding an unruly student, only worsened his condition.
Common Sense lost ground when parents attacked teachers for doing the job that they themselves had failed to do in disciplining their unruly children. It declined even further when schools were required to get parental consent to administer Tylenol, sun lotion or a band-aid to a student; but could not inform parents when a student became pregnant and wanted to have an abortion.
Common Sense lost the will to live as the Ten Commandments became contraband; churches became businesses; and criminals received better treatment than their victims.
Common Sense took a beating when you couldn't defend yourself from a burglar in your own home and the burglar could sue you for assault.
Common Sense finally gave up the will to live, after a woman failed to realize that a steaming cup of coffee was hot. She spilled a little in her lap, while driving her car, and was promptly awarded a huge settlement.
Common Sense was preceded in death by his parents, Truth and Trust; his wife, Discretion; his daughter, Responsibility; and his son, Reason.
He is survived by his 3 stepbrothers; I Know My Rights, Someone Else Is To Blame, and I'm A Victim.
Not many attended his funeral because so few realized he was gone. If you still remember him, pass this on. If not, join the majority and do nothing
