I have been going through so many batteries on my Portfolio lately, I was curious if anyone has used nicads successfully in their machine. I am not sure that the 1.25 volts they supply will be enough to avoid the dreaded 'LOW BATTERIES' warning. Thanks! +---------------------------------+-----------------------------------------+ [ R.

Since the voltage of 1.5V Normal (say Alkaline) actually drops over its life time, the 1.2V NiCad is fine - and actually more stable. I found Polaroid or EveryReady Gold gave me about 2.5 months and Sanyo NiCads with 5 hours fast charge about 1.5 months. David Powers

I have been using them in my Poqet PC excepting there is practically no warning time, i.e., you have to replace battery immediately. Also the NiCd capacity is only 1/4 of the Alkaline. The actual cost of NiCd is 1/30 to 1/10.

As I recall, the portfolio uses THREE batteries, and most chargers I've
seen charge them in PAIRS. What do you guys do with the 4th one? Or do you
have chargers that work with odd numbers of cells?
I suppose it wouldn't be too hard to just discharge the 4th one with a
small lightbulb or resistor; I don't think I'd want to use 2 freshly
charged cells with a 3rd that had been sitting on a shelf for more than a
couple of weeks.
There was a simple hardware mod for the Tandy 100 that allowed the AC
adapter to charge the batteries; anyone looked into this for the portfolio?
