    Is there any need to routinely replace a cmos battery ?
    Can you tell ( via software) if it needs replacement ? or are there any symptoms ?
    Does a mobo "recharge" a cmos battery ?

    Turn your system off by the PSU and if the bios forgets the settings chances are it's the cmos battery, battery normally last years a long time as the psu is typically left on and no they are not normally rechargeable.

    A defective motherboard can cause a battery to last as little as 14 days. A good motherboard and a good battery can go unrelated for a decade or more.

    They are not rechargeable. They can last so long because the rate the motherboard draws from it is supposed to be extremely low.
