I'm trying to figure out what the state-of-the art in market-available
consumer Li-Ion technology is as far as energy density goes.
As far as I know, the highest energy density (mass produced) is 18650
form factor. Please correct me if I am wrong.

Maybe someone can further my electrical education.  I thought I knew
everything about basic E=IR stuff, but apparently I do not.  :)
The scenario:
Black and Decker Dustbuster 3.6 volt DC,  model HV3000.

Hi,
I have the following problem: I am looking for a complete list of
known types of elementary charge transfer reactions, in symbolic form.

Hi All.  Just found out platinum is over $2000 and ounce.  Long time ago, I
built a metal detector that was very good at finding platinum ore.  At the
time, I wasn't too interested in processing it and professional processors
were too expensive.  Things have changed.  The process ...

The inexpensive "smart" chargers all seem to want either 2 or 4
batteries at a time to recharge.  But I have a light that uses 3 at a
time.  What happens if you charge 2 or 4 batteries that are unevenly
discharged?  Is one overcharged, or the other undercharged, or do both

Hello
I have two questions  about batteries:
- The seller of a electronic device  told us that the  Lion batteries
of a newly purchased product require the same  startup conditioning

Yup.... I know I am a boy 13 yrs old (as you called me, that's Ok!) however
you senior citizens ought to hear this, I just got done with the "World 1st
Instant Battery Charger" Invention.... Yup!! Yup!!  Yup!!  15 seconds that's
all it takes to charge a 1,200ma battery, or 2 ...
