Memory effect with laptop battery

[TakedownCA]

I didn't find out until it was too late that you're not supposed to keep your laptop plugged all the time. So now I have a laptop battery that holds a charge all of 30 seconds. If I'm lucky it'll last a whole 2 minutes. I've tried discharging/recharging it several times, but it doesn't seem to help much. If I do It enough times will the battery eventually become useful again? I don't really want to spend $150 for a new battery, so any help is appreciated. Thank you.

What kind of laptop do you have? Is it a nicad or a lithium battery? It could be the charger itself. As far as I know lithium ion batteries have more sophisticated charging systems that prevent overcharging.

There is supposed to be a way to shock a battery so that it can be fully discharged and recharged. OTOH, your battery may have been damaged beyond help.
. You may end up having to send it off for testing to a good battery supplier/rebuilder like (actually I don't know whether they still do rebuilding, but they may be able to point you in the right direction):

It's a KDS laptop with a Lithium Ion battery. If anyone has some more details regarding the procedure to "shock" the battery, that would be great. Thanks.
