Are there cheap rechargable batteries to be used with the Tekkeon?

You can use any AA rechargeables with it.

There is a company called Igo that makes a chargers with interchangeable tips (called itips)for different devices.


The Nxxx chargers use the A69 tip and can be connected to many of the Igo chargers.

They currently make a 2 cell AA charger that can use the A69 tip.
There is also a discontinued 4 cell AA charger that also can be used.

I charger all my devices with Igo chargers , just changing tips.

In the car, I have a 15 watt charger with a splitter so I can charge 2 devices simultaneously.

Some Igo chargers and Itips are sold by Radio Shack.

Igo chargers and itips can often be purchased on Ebay at good prices.

There are some other companies that sell chargers that can also use the itips. Of these, Monster is the best known

Look at www.igo.com for more information.

Go to the YouTube link below to see about recharging batteries using other batteries as an energy transfer medium. After watching Mark Erickson at the link below, if you still don't understand, I suggest watching it over again, it starts to "sink in" after a while. Mr. Erickson neglected to make any mention of diodes, and he seems to misunderstand the properties of electrical tape. That aside, the use of diodes is often necessary to prevent backflow of current from the battery you wish to charge, to the ones you intend to do the charging from.

http://www.youtube.com/watch?v=brdmnUBAS00

The original poster in this thread mentioned he used a diode in his configuration, and stated that he thought the current from his Nokia Internet Tablet battery was flowing toward his external AA battery pack. If this is indeed what was happening, he must have had the cathodinium pointing in the wrong direction to start with, or he obtained his blocking rectifier from a dubious source, such as PolyPaks - Maynard,Mass. or Glenwood Sales et.al. These sources of electronic components have a reputation for selling diodes with the cath band (which denotes direction) marked on the wrong end of the axial package.

Be careful as there is some potential for confluence of the electromagnetic spectrum particularly regarding any chemistry involving lithium manganese dioxide dolly (also sometimes called "Maltese Cross" vocational institution). I did my PhD. thesis on this in 1979. Don't confuse dioxide with dioxin which is quite different. Dioxin is not in the relevant covalent partition (it lacks the free electrons to participate in this spectrum), yet I thought I should mention it here to displace any possible similarity to medical instrument, plural why white T-shirt. Turn left sometimes, but I digress.

If you want to know the actual potential danger in this battery interconnection game you are playing, go here (links below) and see the recent news stories (11/2007). This actually happened to an unfortunate Korean man while operating an electronic shovel on a construction site. TRUE STORY !!

Stay safe my friends..... a little knowledge can be a dangerous thing. Stay in school kids.

When I stated, "(it lacks the free electrons to participate in this spectrum)", I probably should have included the wording, "unlike most other garden variety semiconductors".

I hope this omission didn't confuse anyone. If it did, my heartfelt apologies.

+1 for educated responses. Thanks. Internet forums are all too often filled with quasi-knowledge and it's nice to be reminded that we don't know what we're talking about sometimes.

My pleasure.

That guy in the YouTube video (Mark Erickson) was wrong about needing to match the impedance between batteries. The fact is battery impedance is of little to no concern. I have sent Mr. Erickson three pages of quadratic equations to substantiate this.

I know what some of you may be thinking, you are wondering, "what about FFT?".

If anyone suggests using Fast Fourier Transforms as a viable argument, I think I'll vomit. Only a noob would think that doing a time domain / frequency domain speculative comparison for the sake of conversion efficiency or as a substitute to empirical bench testing has any place in this process whatsoever. Please leave this out of it:

Thank you.

Actually, that was so not what I was thinking.

In fact, what I was thinking, was more along the lines of: "Whuh? Duh? Him heap too smart. Him hit wif club now! Duhr!"

lol, also what I was thinking, except for last part.

I found this item on Dealextreme, perhaps this is what some of you were looking for ?
