- Quad A cells should be available very soon. The lithium chemistry is
- funky as someone said- I think the real open circuit voltage is about 1.7
- volts- be careful when series them because this little offset adds up. I
- evaluated the AA cells in detail for a product I was developing and they
- are suited for rather high current loads, their life in a 48 would be now
- better than good alkalines. It looks like their best application would
- be in a demanding peak current load like a camera flash. The only
- advantage they might have would be to surveyors or others that use their
- machines outside at very low temperatures. Alkalines absolutely puke at
- about -20C, lithiums are good to -40C. Everready is the manufacturer of
- the ones I evaluated, the trade name is 'Litheon'- kind of neat but no
- help. Alkalines are really the best you'll do for a while...
