For a PC RTC?  Damaged electronics, or bad battery.

The electronic components related to the RTC age very well (chipset, ceramic
capacitors, quartz crystal, schottky diodes).

The crystal is easy to damage during motherboard repair work, though (it is
sensitive to heating).

I'd say you've it as well compensated as it is pratical.
