Real life (and Live) runtime test.

[Mike, Lord of the Spammers!]

Well those of you know me will know I've a love affair with the humble Gerber Infinity And there well known for having a very impressive runtime, but just how long will one last?

Well I've just loaded up one of mine with a fresh AA Eneloop, and I'll not turn it off till the battery dies, so let's see...

[Neil]

You figure this kind of test is a perfect match for your insomnia?

[Millhouse]

You might be there for a while.

[Mike, Lord of the Spammers!]

Something like that

At least it'll be company

[Mike, Lord of the Spammers!]

You might be there for a while.

Well I've only changed the battery on it once, and that was because I switched away from alkies to eneloops, and so far that ones showed no perceptable dimming yet, so I'm keen to see just how long it'll last

[Neil]

  You know it'll finally shut down when you're not looking.

[Andreas]

Unless you know the mAh rating of the battery, such a test is rather useless I'm afraid. A new store bought AA battery can have anywhere from 1000 (or lower) to 3000mAh capacity depending on brand etc

[Neil]

He's using an eneloop.  Assuming its not brand new I'd say a rough figure of 1800mA is good. 

I'm going to guess at three days

[Andreas]

1800/3/30=20 hours will be my guess then

[Neil]

Probably more realistic

The Gerber Infinity Ultra was my first LED flashlight (excluding my bike light).  It is also one of the dimmest and bluest lights of the bunch.

Back in 2005, I placed a tired alkaline AA battery measuring 1.39 volts into a Gerber Infinity Ultra and left it turned on. Over 36 hours later, the Infinity Ultra was still lit, though a bit dim.

 AA battery measuring 1.39 volts

That's not a measurement of capacity.

[Mike, Lord of the Spammers!]

Well it's been on 10 hours now, and I reckon it's lost about 20-25% of it's brightness

[Mike, Lord of the Spammers!]

Still going, but it's a pretty feeble light being thrown out now. Close work only!

[John]

I guess 28 hrs 

[Neil]

I want to know what we win if we get it right?

Perhaps more of Mike's special self portraits

No! I meant 280 hours     

[Mike, Lord of the Spammers!]

I'll send them to everyone in this thread anyway

Actually it's bloody dim right now, I doubt it'll last much longer But then there geared to run on alkies, not Ni-MH eneloops

[Mike, Lord of the Spammers!]

And it's dead

18 hours on a rechargeable isn't too shabby in my opinion. And at least 14 of those it was producing usable light

[Neil]

Andreas was closest.

  Now send him the pics 

[Mike, Lord of the Spammers!]

Andreas was closest.

  Now send him the pics 

Let me get pissed up first

[Andreas]

damn my math skills >.<

[John]

damn my math skills >.<

Say that when you get Mikes pics   

[ryan1835]

only 18 hours?

[J-sews]

Did you sit and watch it the whole time Mike? That sounds as exciting as watching the grass grow. (or watching paint dry)

[NutSAK]

damn my math skills >.<

Did you measure the current draw of a Gerber Infinity?

I did a "real life" test on an Gerber Infinity Ultra once, with alkalines, and it was still producing usable (dim) light after 48 hours.

 AA battery measuring 1.39 volts

That's not a measurement of capacity.

I should have specified that the battery I used was an alkaline.   A voltage of 1.39 volts in an alkaline battery is evidence that it has already been partially discharged and no longer has full capacity.

I know, but it's still not a measurement of capacity. It's about as inaccurate as saying you have a used battery.

I don't recall Parnass ever saying it was,all he said was he tested with a alkaline AA battery and got 36 hours of light

My lifes not that dull yet
