My 803T blu-ray

[daguin]

hehe I should have known better (I was thinking that was old and new batteries)... Thanks for the help though!

I'll buy some of those batteries, although they seem kind of uncommon. I could order them from dealextreme, but that would take a year.

Does anyone happen to know if aaa dummy batteries exist?

...Or just solder a wire between the terminals where you'd put a dummy battery

 

[new_laserman]

interesting interesting. Thats nice.

I think I may have found a winner!

2x http://www.dealextreme.com/details.dx/sku.11386

Dimensions: 1.34 in x 0.63 in x 0.63 in

the base of my flashlight is ~3 inches.. take away 1/4 inch for the threading, that leaves me at 2 3/4inch and each battery is 1.34 inches long soo that is 2.68 inches... and the sping is 1/4 inch.... the only thing is that they might be too skinny

My experience.. I had an MDXL light that took the 3xaaa battery cage. Two CR123's were two long, too thin. Two CR2's fit just fine, but again were too thin..I had to make a "spacer" to go around them. It will work well, though, as long as the spring will hold them tight enough together.

You will get better battery life out of the rechargeable CR2 size, although they are harder to find. If you find them, MAKE SURE they are the 3.7v variety, NOT 3.0v.

Just order some 10440's and a charger. They are available from many domestic battery houses. Google 10440 & battery.

True.. this is the best advice. The 10440+charger can be found in the US(faster shipping), and without saying, require less "rigging".

The Rechargeable 3.7v CR2 on the other hand I have ONLY found from China.

I found 10440 batterys but I cant find a charger for them.
http://www.batteryspace.com/index.asp?PageAction=VIEWPROD&ProdID=2598&strVarSel=510 for the 10440 battery
will an aaa charger work from that company? ( I'm assuming not).
hmm.. will keep looking
EDIT: http://www.batteryspace.com/index.asp?PageAction=VIEWPROD&ProdID=1421 maybe?

 

[MarioMaster]

no, normal battery chargers won't charge lithiums properly - heck it might even blow up, lithiums are touchy

 

[iccy]

Gosh this is getting ridiculous! I found batteries and a charger but http://e-lectronics.net/nano-charger-lithium-10400-size-battery-p-415.html has a charging current of .4 amps, and the charging limit for http://e-lectronics.net/lithium-104....html?osCsid=4f7fcad84e21092e8c69e4065d05aac0 is 300mA!
The charging limit for http://www.batteryspace.com/index.asp?PageAction=VIEWPROD&ProdID=2598&strVarSel=510 is 350mA xD
http://www.dealextreme.com/details.dx/sku.974 looks exactly the same as the e-lectronics one also, so im assuming 300 mA.

is there a mod I could do to the actual DRIVER?

build your own. google.


edit: i would reccomend protected batteries. theyre not something to skimp on. i dont want shrapnel in your remaining eye.

 

[iccy]

More to come!

I am just waiting on my driver

im not aware of any companies that make protected 10440's, they're too small

Yup... you'd have to build your own protection circuit, but it may just be easier to pay attention to when the output dims.  I had posted the idea previously to use  zener diode that has a voltage around the cutoff for the batteries to sort of "turn off" when it goes below... but no one seemed interested, so I forgot about it.

As for the CR2s, if you could find the 3.7V ones, they would work.  I rolled up a piece of computer paper tightly and cut to length to insert as sort of an adapter since the length of 2 is about the same as the AAA battery holder, they're just thinner.

hmm I'm having trouble finding the 3.7v ones in general. I've looked at walmart and I could only find the 3.0v lithiums.. 2 cr2s=6v minus 2.25v = 3.75volts going to the blu-ray diode.
I hope 3.75v is enough ><

The diode need 5V. You may have to go to a battery specialty shop or hit an online source for the 3.6V batteries.
