They are the same size but they are different in chemistry. A 10440 is a Li-ion cell which has a voltage of 3.7V and 4.2V at full charge. The energizer is non rechargeable with a voltage of 1.5V

edit: 10440 is basically aaa size.

As said by Zeebit, I do not think they will work. Plus Energizer batteries add up really fast in cost and I have found them to not be very durable on my laser's. There are plently of companies that sell Lithium(Rechargables) if you hate using UltraFire :)



Do you have a link to the laser?

Alright,

I'll give you a link to a good battery store. I have to find the link again haha :beer:

BTW: I don't think that is true 100mW, seeing it's only $44 :)

Ye I didn't really need anything more than a 50mw so I figured I'd go for the 100mw as it's probably under spec.

There are not much other 10440 brands except trustfire/ultrafire/*****fire.

You have a cheapie laser, ultrafires are cheap and you can also get a $2 charger on eBay. Just be careful with these because they're well, cheap.

Forget the energizer ultimate AAA and use the 10440 lithium ion with a dummy AAA cell they work very well and more power output usually 15% more compared to normal AAA batteries and you can recharge them....the energizer ultimate AAA batteries are great batteries and last a lot longer but cant be recharged. So they end up being very expensive in the long run .



QUOTE=M3th0D84;1243435]So as the title stats.....

Tried Google search but to no end :/

Energizer Ultimate Lithium AAA Batteries

I've found the above batteries, just wondering if I could use these in my laser pointer rather than the cheap ultrafire 10440 one's I have.[/QUOTE]

ALMOST FORGOT!!!!

Before using it, get safety googles, seeing at how cheap it was, Im sure there is no IR filter whatsoever.

an energizer ultimate lithium is comparable to half of a 10440 (when talking about voltage). i took a reading of an ultimate lithium out of the box and it read about 1.9V, whereas half of a 10440 would be 2.1V @ full charge. So, if you have an application where rechargability is a must, you can use a 10440 and a spacer (most of the time). though sometimes sensitive devices can't handle the extra power such as a cheap 3V True 5mW module. most eBay pens can handle the extra voltage though.
