Dave actually after you pointed it out your right so they step up the voltage....hmmm let me give this thing a good looking over.  they'd have to be in series to up the voltage.  The darn ends look so similar....more later

Something "clicked" when I saw that photo.  I made a battery sled for my 680 by wiring two 8 AA cell holders in parallel, keeping that voltage around 10.6 but doubling the amperage for longer runtimes.

I have a couple of the 7.2v DVD batteries and the case is smaller; makes me think they use the same 6 cell config, just eliminated the "step-up" circuitry.
Just guessing, really.

OK so yes the batteries are parallel x 3 and the three pack is in series for 7.4volts total.  So to get 9 volts they step it up.  I had two bad packs and had forgotten that one was 7.2V.  So the red batteries are in a 7.2 volt pack.  The orange are in a 9V pack.  It was suggested  to make a box that the batteries could be replaced but after looking at it closer there is no way I have the skills to take that project on.  Too many parts, and too much of not knowing what the hell I'm doing.

Kirk...look for two Tekkeons coming your way...they are dead so no loss if they can't be fixed...I have two more that are tired but still work so hopefully it can be done!

UPDATE:  It looks like I can add the Tekeon 3450 to the refurbish list.  I cannot find a source for the stock battery pack but it measures out internally that the DVD style batteries will fit with just a little work.  To restore it to stock rating and capacity all you'll need is 2200mAh capacity batteries, which are some of the cheapest out there.  But I will need to charge $20 due to the retrofitting of the batteries and labor involved in rewiring a completely different style battery in place.  You could up the capacity if you wanted.  Your choice.  Here are pix of one opened up.

Sweet...so to increase capacity just order six of the 1 X UF 18650 3.7V Rechargeable Battery 4000mAh with Tab, same as DVD battery?

Oh...I was looking at another thread...what do you think of these?

http://www.all-battery.com/37volt-3200mah20cli-polycell.aspx

the 2200mAh was discontinued

Hmmm????

This one on ebay is too wide to fit them side by side. PLUS the have circuit board of some sort that is not on the originals.  That is the only kind I found on the web too. 

The Tenergy link is the correct one BUT @ $11/ea plus shipping I'd still opt to retro fit the 18650 style in the case.  You're at $66 just for those Tenergy batteries. about twice what the other cost.

Dimensions of existing cells:
(98-100)mm Long X (32-34)mm Wide X 5mm Thick.  Two stacks of three cells side by side.   MUST be six cells since each one has separate attachment point on circuit board.

The circuit board's twelve individual attachment points for each battery and the associated electronics are too complex for me to figure out if they can be circumvented.  I would only want to tie new batteries into the existing solder points.   Adn it does not appear that there is a direct replacement battery available for the Tekeon 3450

whats the size confines for the 3450 series if we are looking for replacements. If that's already been posted, my appologies.

No Page not exactly here is the space size limits:
70mm Wide X 100mm Long X 19mm High,  It is JUST enough height to fit six of the 18650 batteries as you can see by the photo.  I drew the black line with a sharpie to show halfway point.  And there is a picture of the circuit board they attach to. So I could attach six of the 18650 batteries with some wiring, shink wrap and patience and I think still get the case to close.  It will be right at the limit of the height.  Maybe it will have a wrap of gaff tape or extra large shrink wrap to ensure it is solid, we'll see.
