Many early Macintosh computers, such as the Mac SE, have soldered PRAM batteries. While designed to last for many years, these batteries are now decades old and prone to leakage.

While modern computers have straightforward BIOS batteries, the PRAM battery in vintage Macs was often hidden deep in the analog board or soldered, encouraging a "no user-serviceable parts" ethos. However, the community has kept these machines alive by finding modern replacements, like this Keystone Electronics 108 1/2AA Battery Holder. 4. Exceptions to the Rule MACINTOSH PRAM BATTERY

Later Power Macintosh models often require a working PRAM battery to function properly.

Enthusiasts often carefully cut or desolder these old batteries to remove them before they destroy the logic board. 3. "Not User-Serviceable" (Technically)
