Can a "dead" rechargeable battery be resucitated? Answered

I have a Filter Stream Ultra Dust Tamer 4500 that doesn't recharge.  Is there a solution; a replacement part; any help at all?  I really don't understand rechargeable batteries.  I think they may get fried if the transformer is left plugged in too long??  How long is too long?  I know this question applies to all rechargeable batteries with transformers, e.g., cell phones, portable vacuum cleaners, cameras and on and on.  Thank you.

What type of battery is it? size? chemistry (nicad, nimh, or lithium?)

nicad has a trick of zapping it with a medium voltage, high current spike to dissolve crystalline shorts in the battery -- sometimes renewing its lifespan

nimh, once it's done, it's pretty much done, same with lithium, and usually needs replacement -- you can usually make a new battery pack out of new cells that match the old ones' voltage.

Re my question about dead rechargeable batteries: Thank you, all three of you who answered.
I am always impressed with the knowledge that folks possess. Bottom line, most of what you all told me is way beyond me and/or my very limited tool supply. But thanks for your responses. And sorry for the delay: I swear I just got notified of the most recent response. You two who wrote in Dec 2010 I only found out about.
I decided to just get rid of the battery operated dust-inhalation canister section of this duster and now I use my electric vacuum cleaner attachment to vacuum the dust out of the duster. What was I thinking anyway when I plunked down $80 for this device???
Thank you.

you can try zapp the battery by conecting one electrode from a welder in one of the contacts and put a drop of weld on the other. BE CAREFUL! the battery can explode and you get burn with the acid. if you prefer you can get a wall transformer with the same voltage as the battery and change the vaccum cleaner to wired one or buy another battery or vaccuum cleaner
