Primary battery users

[vb14]

When the primary battery in you your multimode light doesn't have enough juice to power the "high" mode of your light, what do you do with the battery(ies)? Do you throw it away? Or do you wait until the battery is fully drained?

Thanks.

When my E1B can no longer power up on high, I pretty much immediately replace the battery. I don't want to need the high some time and find that the battery will only power up the low mode. Although I have found that the low will run for 2-3 more hours after high will no longer light on the E1B.

Search for the "battery vampires" thread. There are certain lights that can make good use out of those near death cells. I believe one of them is the Inova T5 (?) but that's from memory.

I've got one in my L1 cree right now that just won't die. I use it when I only need a few lumens!

In the past I would leave the drained batteries in for a little but just to use it for the low modes.

However, I'm building a battery vampire to take care of that.

Easee, . . . I put that battery in the charger and put a fully charged battery in the light, . . . done.

the OP is talking about non rechargeables...

me personally, when i use to use incan, i take one of the cr123a and throw it in my p2d till it drains.

now and days i just throw them away because i dont have my p2d any more...

Good question.

They are good for around the house at night in many single cell lights such as the L1, KL1/E1e, P1D, etc. Often it is all you need to navigate around.

I use partially depleted primaries to light my keyboard up at night I put 3-4 AAs/AAAs in series with a variable resistor and crank it down to the light level and drive a luxeon with it. I used to put them in battery vampire lights but too often they would drain so much they would leak and damage the lights.

I do the same with my L1 Cree. It's my best vampire for those batteries.

I throw them away immediately.

 

[Outdoors Fanatic]

I replace them as soon as possible. The used batteries go to my bedroom vampires.

Yup built/buy some battery vampires.

Also about the L1 Cree, I've done that too. Put some used CR123 in it and it just keeps going!

Gerber Infinity are also good vampires, takes the used AA alkalines and still shines.

In the case of AA''s I put them in my handheld gps and get an hour or two run time on it.

Red Inova X5. Best battery vampire ever.

 

[Dude Dudeson]

I throw mine into an old 30 lumen LED light of unknown manufacture to use as a "moon mode" light by my bedside.

I have no idea how many hours they'd last this way since I've just started doing this.

That light is like 6 years old, so eventually I'm going to look into a tiny 1x CR123 light with an ultra low mode for this purpose.

Here's the CPF battery vampire list:

I just chuck them. I don't bother with a "battery vampire" or anything like that. They aren't that expensive if you buy from batterystation or somewhere like that.

You chuck lithium batteries in your regular trash?

 

[vb14]

Thanks for the replies. I, too, throw them away right away. But only because I didn't know about those "battery vampires". It might be something I will have to look at. But do I really want to buy a light just for this? And stock a pile of "almost dead" batteries? My wife already calls me a packrat as it is ;-). Well, at least now I have another option.

Btw, this is for an E1B light as well. It's my daughter's, and she plays with it almost everynight with a either a blue or red filter on.

Again, thanks for all the help!

I do, at least a dozen times a year, probably more.

I tend to use the partially depleted batteries in my Inova X5 or occasionally a Fenix P1 or SF L1 to use them up, but if too many of the half-used 123 cells are laying around, I just throw in them away (in the regular trash).
