Has anyone here tried to rebuild a PowerBook 100 battery pack?
If so, were you successful?
You can't. They are a Sealed Lead Acid battery, and whilst there may be several "cells" they are most likely not self-contained cells that can be removed individually and replaced.
The PB100 is the only PowerBook that uses SLA battery technology.
I knew they were SLA, but I was hoping someone had figured out a way to gut the case and put other cells in.
I remember a couple of vendors selling a non-SLA battery pack but I never bought one and a quick search shows that nobody makes any now (which doesn't surprise me).
The PB100 was my first laptop. I bought it at Computer City back when they were dumping the final inventory. I can't remember what it cost but at the time I remember it was a steal.
I upgraded the memory to 8MB and the hard drive to 40MB. I upgraded the modem but I can't remember if it was to 9600 or 14.4K.
I had a PowerBook 100 a few years back and I searched long and hard and finally found a BRAND NEW SEALED battery never used, on eBay, Apple-branded PowerBook 100 Lead Acid battery. It arrived, I installed it, and found out that it was dead.
So even if you find a new one, chances are they will be dead by now since they are so old (20 years old) and nobody makes them anymore, at all. You will probably not be able to find one, there is no demand for them. They still do make the batteries for the 140/145/160/165/170/180 series machines which are NEW and can be easily found on eBay -- but these are NiCd batteries, not Lead Acid. The Macintosh Portable batteries can be easily rebuilt with new cells, however, and function as new batteries. The problem with the PB100 batteries is that they are sealed and you cannot replace the cells.
Indeed. IIRC, the shelf life of a SLA battery is 12 months.
