Why a dicharged battery works for some time when used again ?

because the residual current collected over a period of time keep the exhausted battery work for a while.

You should remove the batteries because even if they are not used, the chemicals in the battery can eat through the housing and damage the device.\n\nAlso, the chemicals in the batteries have a "shelf-life" where they will react slowly even if there is no electrical discharge.

It may be related to the humidity in the air and the contact interface.  If you have some batteries of this type, try them in a humid room like the bath.  Let the batteries and device sit out in the humidity for 30 minutes or so.

Batteries use the different potential that certain chemicals have. Battery consists of 2 chemicals which potential different are significantly enough to generate voltage difference. Reaction happening in a battery is redox (reduction-oxidation) which allows electron transfer. Positive terminal of the cell has the higher potential.\n\nAs the reactant are all used up, reaction reaches equilibrium. This is when we found out that the battery is 'dead'.

after a while the battery stops charging u. the lawyer doesnt

you said your laptop is 3 years old. if the battery is of the same age you're a lucky person. a battery seldom last that long when used daily (that's my personal experience).\nas already mentioned before, the battery is gone and you have to replace it.

Your motherborad battery needs to be changed. \n\nComputer saves the Date and Time in capacitors which use power from Li-Ion cell on your motherboard. \n\nReplace it. It's very cheap.

For the battery life, I heard that it's better to take out the battery when you're using the AC adapter, unless you specifically want to charge it.\nOtherwise, the battery will charge, then discharge a little, then charge again, etc. and this may wear it out.\nFor the same reason, use the AC adapter whenever possible.\n\nBesides that, just be careful not to hit/drop/spill something on the notebook.\n\nAbout the first answer: "Frequent full discharges should be avoided when possible" and "Avoid frequent full discharges because this puts additional strain on the battery" (see the source below)

That is a pretty old laptop.  I suspect the battery may be so old it may never charge and you will have to get a new one.  One option though is to put the battery in the freezer for a few hours and then give it a couple of days to charge up.  Some times this can revive an old battery for awhile longer.

My iPAQ does that, are you talking about a Pocket PC or laptop or perhaps a tablet PC?\nIt is trying to figure out how much battery life is left..happens especially when you have a complete battery discharge then recharge it.

if you got it used. then the batt is dead. if you got it new ans under 2 years. then i would also have you systemboard checked out. some dells systemboard for laptop came from compal systems. that did make systemboard that where bad contacts that charge the batt.

Basically what it's saying is this:\n\nThose battery tester strips have a special ink which allows for the batteries charge to travel across it.  The more charge the battery has, the further it can travel.\n\nSo, when you test a battery, and it's charge is weak -- it's charge will only 'travel' partially across this special conductive ink.\n\nThe thermochromic and normal ink mentioned are largely for display/cosmetic purposes.  These basically allow you to see how far the charge has travelled across the conductive ink layer -- and thereby see that this battery is "good" or "bad".  \n\nHope that helps.

Rechargeable battery can sink in the current whenever its voltage is lesser than the input voltage and up to its maximum capacity. This process is called charging. \n\nIn case of non rechargeable battery the capacity of the battery will be zero. So the battery will oppose the flow of current. Whenever this opposition is quite strong or very fast, there will be force from both directions. Due to this force, the battery will explode.\n\nThe same phenonmenon can take place even with rechargeable battery which is already full and if it is overcharged too quickly (that means without using any series resistor or overcharge cut off sensor in the circuit).

Contact dell and tell them you want a new battery. dont leave it any longer, cos after the 1st year they dont want to know about the battery.\n\nTrust me your battery is fubar, its happened to me several times.

It cause u nothing dear. It works on the battery. It helps u by noting dates, battery power etc, Ok na

Discarge Battery, Take the Battery Out, and store in Fridge, Fully Charge before using again.

If you jump start it and then run to the store or school, the battery is not getting a thorough charge. \n\nFIRST step: Charge it with a charger or drive at least 50 miles, while observing the gauge.\n\nNEXT: check the battery cable connections for corrosion.\n\nNext: check the charging system for proper output.
