Laptop battery question

[Adam in CO]

So, I replaced the original one and it does last much longer but now I get no warning about low power. It just locks up. It is defintely at the end of its cycle because it doesnt even really have enough power to boot up, run a disk scan and log on but I would really like to have a warning before it locks up.

Disc scan wont help. Try cycling the battery by putting it in. Running it down and then charging and run it down again...
By exercising the negative to the positive elements. The battery becomes stronger and learns to last

That will only work on Ni-Cads that are not to far gone...

don't do chit on Lithion-ion or the newer one(can't remember name)

i learned my lesson....running a dell xps m1710, battery went out in 12 months. I was always on the charger either at home or the office...so now with the new battery, i run up the charge then let it go down to low batt warning. Hope this lets me get more than a year out of the battery!

RYD,
Surprised you remember many things however principals of electronics do not change much with practices of battery. Since Edison charging of batteries have not deviated.

So in essence, what you're saying is the Nickel Cadmium battery has/was never known for building up a "charging" Memory? You know, often resulting in a lower state of charge, rather than full charge.

I'm not getting the RYD's back on this one, however....

Adams question does not pose type of battery in question. My proposition is there is nothing new under the sun!

Among my MANY areas of expertise (spelling is not one of them) I know LOTs about rechargeable batteries...

Ni-Cads posess what is called memory...if a Nicad is suppose to give you a certain service life (time or shots or flashes) but you frequently DON'T use it to its full extent and go on to recharge it time after time after time it will remember the NEW usage you are asking of it (meaning less demand)...you can re-educate it by taking it all the way down, then recharge, then down and recharge, maybe several times and you can bring it up to original specs...this generally works in the first 75 to 80 % of the batteries usage (life)...the last 15 to 25 % of battery life it may NOT be possible...depending on the indivual Ni-Cad they can be recharged 500 to 1000 times (YES there are exceptions)

Lithion-Ion rechargable batteries HAVE NO MEMORY PROBLEM...there is a recharge life on them as in ALL rechargable batteries...there should give you OVER 1000 recharges...

if you want to know about LOX vs NOVA I can also discuss it...

Ah, I understand.
