    Hi,

    I'm a newbie here. Apologies if this subject was tackled elsewhere. It does not appear to be.

    I would like to replace the LI ion cells in my laptop battery with LiFePO4 batteries.

    Can this be achieved safely?
    Would it be possible to use the standard laptop charger power supply to charge the batteries without damaging them?

    Any advice on the matter?

    Regards

    you would need to replace the integrated battery monitoring stuff and you would get lower capacity.

    The former is more of an issue than the latter

    Thanks. What does that really imply? Are you referring to that bit of circuitry found inside the battery case?

    Yes, the circuitry inside the battery case at a minimum. Possibly some of the circuitry inside the laptop as well
