I have a Toshiba Portege 7000CT with a dead CMOS battery. After a lot of careful prying and disassembly, I finally located it tucked away deep inside, lodged in a small crevice bedside the internal speaker. It has also leaked terribly.
This battery is a NiMH type, not lithium, so I had to order a special replacement. It's very difficult to impossible to get an exact match that also includes the right connector, so I will often have to snip the old one off and solder it to the wire of the new battery.
When trimming back the wire, I was surprised to find that the corrosion has actually progressed quite deeply down the negative wire. I kept trimming until it was finally clear.
A bit of flux, a dab of solder, and some heatshrink, and the repair is complete. I secured the excess wire with Kapton tape and used double sided foam tape to hold the battery in place.
It was an absolute chore to get at this battery, and there would be a risk of damaging the plastic each time doing so, so I routed the battery wire into the hard drive bay, where there is plenty of extra room when using a CompactFlash adapter.
