These batteries for the laptops cannot be revived or extended. over time that cells in these batteries eventually fail. The newer laptops are starting to use the newer Lithium Ion power cells that do not get Cell Memory and can be used over and over regardless of charging procedures. E-Bay has several good US sellers and shippers that are relatively inexpensive.

Frequent Charging Shortens Battery Life
Frequent charging shortens the life span of a Lithium ion battery. Batteries should be charged only after they expend all their power.
Switching batteries helps preserve battery life: If a cell phone or computer user puts in a spare battery while separately charging the primary Lithium ion battery, that helps extend the life of both batteries.
Most laptops charge the battery when a user plugs in the AC adapter. Users can adjust this setting by changing the power options. Windows places this option in the Control Panel, while the Gnome Linux desktop places power options under "Administrative Tools". Cell phones incorporate their own power-saving features that the user usually cannot control.
When to Replace a Lithium Ion Battery
If a laptop battery does not hold a charge for more than a few minutes, a user must replace the Lithium ion battery if he wants to use the computer without an AC adapter.
Other Ways to Extend Battery Life
Storing a battery in a cool, dry environment causes a lithium-ion battery to last a little longer and reduces the frequency of needed battery replacements.
hope this helps
