Lithium 9 V Battery ??

[ViReN]

is there any thing like a Lithium 9 V battery .. similar to a the commonly used 9 V Alkaline Battery

Re: Lithium 9 V Cell ??

I have seen them in a non-rechargeable. Can't remember exactly where. But I have seen them. So they do exist.

Yup, Energizer L522, 120 mA max, 1200 mAh, ten years, neat part. Expensive.

There are also the Ultralife ones that you sometimes
see in long battery life smoke detectors.

WoW ... thats amazing...

Special Thanks to Doug Owen for the PDF Link /ubbthreads/images/graemlins/smile.gif

Gerg thanks for the shop link /ubbthreads/images/graemlins/smile.gif

this means.. that since such a thing is available.. it can make a great survival light

Sheet Says ....24 hours/day 10 mA 850ohms load ... 130 Hours 1300 mAH....

we can drive a single Next Gen Nichia @ 20 mA ... and it should do a good 65 Hours /ubbthreads/images/graemlins/smile.gif

or should we go in for a buck regulator (for extended battery life?)

Naw, run *two in series* at 10 mA, a bit more light and twice the run time. As the discharge curve is pretty flat, simple resistors work pretty well.

This is exactly what he PacLite does, right? Two LEDs in series on the Li battery (alkaline is the alternate, the Li is 'factory'). They run 150 Ohms for 16 mA on high, 3,000 Ohms for 1 mA on low.

BTW, not to quibble, but about the title.....one is a cell, 3 in a box makes this a *battery* right? We get mighty loose with terms around here sometimes...

Re: Lithium 9 V Cell ??

last time I was in the local Ace Hardware store, they had some lithium 9v batteries next to the smoke detectors.

 

[ViReN]

Oh /ubbthreads/images/graemlins/smile.gif thats a nice thingy ... 2 in series with a 150 ohm resistor .. excellent...
and a product is already available.. thats even great /ubbthreads/images/graemlins/smile.gif

Doug: Yes chief /ubbthreads/images/graemlins/smile.gif ... I am sorry i missed the term /ubbthreads/images/graemlins/smile.gif ... i edited the submect ....

Those batteries are used in the famous/infamous Pak-Lite. They're around $10 at Radio Shack or I think I've seen them online at around $6 or $7.

 

[ViReN]

the cost is high.... as compared to standard 9 v alkaline battery

but when it comes to ultimate survival... (like keeping one in the first aid box) etc .... it's priceless especially when we think of a 10 year shelf life of a lithium cell ... ... granted that these lithium's are dangerous to handle ... but with a right protection circuit.... we can make them a bit safer.. than the current standards...

 

[flashfan]

This is great! Thanks for the info and links.

IMO 123 cells are cheaper at $1 each and have 10-15 years shelf life also and there are many cheap 123 based lights being sold on CPF often compared to almost no 9v based lights.
This is probably why 9v lithium based lights are not popular.

 

[markdi]

I bought 10 lith 9v batterys sealed in some sort of foil/mylar pouches for 25 bucks at the flea market.

 

[ViReN]

main problem with the 123 cell lights is the cell voltage is 3 volts.. and we need to stepup the voltage.. ... where are with the 9 v battery.... we can just use a resistor... (making it more reliable) ....

also... the runtime of such a light is very very high... as compared with the 123 cell light.

 

[Lynx_Arc]

Use 2x 123 batteries in series and a buck circuit or resistor... not sure of the runtime but you could even go to 3 of them if size wasn't a problem and have 9v lithium essentially.

 

[paulr]

Those 9V lights snap-on lights aren't all that rugged or waterproof. Tek-tite makes a survival light based on a 3.6 volt lithium chloride AA cell direct driving a single LED. It's dive rated to 1000 feet or something like that, and supposedly puts out reasonable light (comparable to CMG Infinity) for 200+ hours.

I know kodak use to make some a while back. I used them in the radio transmitter for my tyco radio controlled cars. They lasted for ever.
