Short: swap NiCad battery with Lithium coin b. Author: wwt5491@rit.edu Uploader: wwt5491 rit edu Type: docs/hard Architecture: generic This document describes how to replace a NiCad battery in your computer with a lithium coin (watch) battery. When NiCads get old, they can leak battery acid, which can eat traces on your computer and cause some rather serious damage if not taken care of quickly. Lithium batteries won't leak this acid, so are safer for a computer you plan to have around for a while. If you plan to replace your battery soon, consider going lithium, as putting another NiCad back in offers the same damage potential as your current NiCad. This hack works for any NiCad battery setup, A2000, A3000, bridgeboards, A501s, PCs, etc...
