10440 Options

JLSE · Nov 12, 2010

Being a long time user of DX batteries, I haven't really
bought elsewhere.

I have trustfire 10440's from DX, and they are great for my
smaller builds. Problem is, these hungry 445 LD's empty them
quick at higher current.

What are the options for 10440's other than re labeled batt's
made by the same manufacturer?

Im looking for the highest possible current in the 10440 size.
Protected or non protected, doesn't matter just power..

All links and ideas welcome :beer:

I am pretty sure Lighthound has 10440s, AW brand, only unprotected (Because they are so small), but AW has been known to be one of the best for High drain. You will always run into the capacity problem though, because they are so small.

Good luck

Thanks for the link :beer:

This is the first time ive put a really high demand on the
10440's..

I made another pen as seen in the below pic, but
this one is just shy of 800mW.

The battery empties far too fast.

There are really not a lot of options. The AW 10440 is the best around. Batteryspace has one with the same specs but I would assume they are the same just packaged differently. .7A max discharge.:cryyy:

May I ask where you got that lovely host?

Im squeezing 760mW with an aixiz glass..
Even though it heats up relatively fast,
the battery seems to crap before the heat
becomes an issue :banghead:

I had seen cells that are AAA diameter, but shorter..
Im thinking 2 of them and a LDO driver?
Was also thinking 2 'N' cells at 3v, have to
see whats available..

Its from DX, but you need a lathe to cut down the
aixiz mount to 8-9mm (cant remember exact).

Toaster · Nov 12, 2010

What kind of driver you using, and why would you use a lathe to cut it, wouldnt a grinder work?

The driver is my boost driver..

The reduction in size applies to the
diameter of the aixiz.. not the length.

If I used a grinder for that, im sure the
beam would exit lopsided..

Toaster · Nov 12, 2010

Your boost driver? Dr Lava? Or a custom. And sorry, I am just not seeing how you cut it.

JLSE · Nov 12, 2010

I didnt take any pics of the module but below is the driver.

The .id of the host is approx 8-9mm and the .od
of a standard aixiz module is 11.9mm

You cannot fit the aixiz inside the host without A- drilling the host,
but the inside is threaded so that is out... Or B- reduce the outside
diameter of the aixiz module..

Turn it on a lathe and reduce accordingly... :beer:

Wannaburn, are you using a boost driver with that? You should know that in order to boost voltage on the output side, you have to increase the current draw on the input side.

Highest possible current is easy, but highest possible maximum safe current you will not like to hear. Most 10440s seem to be around 300-400mAh. General rule of thumb for LiCo is safe max discharge is, in amps, twice the cell capacity, or 800mA.

I haven't seen any LiMn 10440s yet, but I haven't really been looking. I've heard whispers and rumors about a 10440 LiMn that the vaporizor crowd uses, but haven't researched whether it is LiMn or just labeled that way. These, if they ARE real LiMn, will be able to safely supply a higher current without catastrophic failure.

JLSE · Nov 12, 2010

Yes its boost.. To keep the voltage up the
driver indeed draws extra over the current that the LD sees..

I think 600-650mW is going to be the upper limits
on these pens :banghead:

The heat wasnt my concern, just wanted to get the most power
for its size.

My driver is stable down to 2.4-2.5v, so maybe I can find a
solution in a 3v configuration..

Either that or 2 x AAA in a pen host. Problem with the pen
host is that the walls are thinner and heat up much faster.

These little guys are just under 3oz.

hello gents,
I am also building max power 445nm pen laser (jarob pen host, Flex drive V5)

I will be using a single 10440 for only short bursts of no more than 5-8 sec Max ON at the time. Its just for demonstration of technology in slim host.

I was wandering if anyone compared these two suppliers of 10440s yet?

This one is labeled "Protected" from DX (500mAh) considered ~350mAh by seller
DealExtreme: $5.03 UltraFire Protected 10440 3.6V 500mAh Batteries (2-Pack)

and

TrustFire labeled "Protected" from DX (600mAh) considered ~350mAh by seller
DealExtreme: $5.08 TrustFire Protected 10440 "600mAh" 3.7V Rechargeable Li-Ion Batteries (2-Pack)

VS. more trusted AW brand, which are unprotected and labeled 340mAh. - almost twice the price of the above batteries!
AW 10440 Unprotected Rechargeable Lithium Battery

i have feeling it is ALL same merchendise.

best regards

Hey WB,

If you are looking for "N" size Rechargeable cells they are called 14250's.

They are to large for your application. Here is a picture of them stacked next to a 14500 cell.

The "N 14250" cell size in this picture are 14mm across by 27mm tall each 14250 cell and they are Protected Lithium Ion Battery, 350mAH, 3.7 volts.

On the Other hand the throw aways are a lot smaller in size compared to the picture above. So they might just fit.

Here is some picture i took for you comparing them to a 10440 cell and 14500 cell.

I hope this Helps.
