Re: Battery Life Issues...

Thanks for your ideas:

<<  If it takes the Hitachi VM-BPL13 (1350 mAh) Li-Ion battery, I know the
 Sony NP-F550 (1500 mAh) battery will work (Have two for my IBM PC110),
 and the Canon BP-911 battery is -said- to fit (1650 mAh) (Need to find
 one & look);  I know for the PC110's, "faking" an AC adapter by using
 external battery packs connected to the AC adapter connector works (but
 isn't necessarily the most power-efficient method possible.)

   One possibility, make a "fake" battery, with cables to go to several
 identical batteries in parallel (or to a switcher off of an affordable
 battery pack;  The Sony NP-F550's run $59.95 US locally, so 8 of those
 in parallel to give a 10-hour lifetime runs $480 roughly, plus tax.  And
 charging might be a problem there!)

It might benefit everybody if those of you who know something about these
power issues ( Changing a light bulb scares me <g>) That a generic solution
for an "extended battery pack" that would work for many system configurations
with some minor cord connection alterations, should be worked up.

Most wearable systems will have a standard battery that will power the system
for 2 hours, but have a "add-on" battery pack (as these may get heavy in
relationship to the overall sytem weight) that could be worn separately and
connected to the system on an as needed basis.  

Many have talked about running more than one battery in "parallel" for more
run time.  This maybe the direction to go.  Find a reasonabley affordable and
rechargable battery type, that could be linked up 1-2-3-4... as each user
determined the run time needed for their specific application.   For example
the maximum run time I would really need before I could access another fully
charged battery, would be 5 hours.  Other may need 10 hours. 

So is this a feasible plan? Or are there just to many variations in mAh's,
watts, or whatever?
