    Is it possible to revive a dead laptop battery?

    my HP laptop battery is so low on capacity nowadays. Please advice on whether or not it is possible to revive it. Thanks

    Generally not because all rechargeable batteries have a finite life. It's likely it's a Li-Ion battery, so one thing you can try is to shutdown the laptop and leave it charging for a few to several days. Don't turn the laptop on again for at least 2 to 3 days. Sometimes that can revive the battery, but it will never have the full capacity of a new one.

    No because laptops have rechargeable batteries and have a specific life time.. You can take a chance by putting laptop on charging for 24-48 hours may be it can add a little boost a little life to your battery.. But in option you need to replace it....

    Another process to try may be to completely discharge the battery and the give it a full charge (as much as it will take).  It may take a couple times, but rechargeable batteries occasionally need to be completely discharged and recharged to work at peak capacity.  If this (and any of the other suggestions) doesn't work then the battery has probably reached the end of it's useful life.
