Using foil to make batt connection

My varitube came with batts that didn't have a nipple, I used them just a couple of times because I ordered some better ones. It didn't occurs to me that the new ones had a nipple and really didn't think much about it, but when I put the original ones back in, the no longer work... Perplexed. Did the nipple shove something up so that the non-nipples no longer make contact? I folded up a piece of foil and put it in before the batts, and it works. Question is, is this ok?

 

Try a rare earth magnet I do this all the time
foil will work but it could short out

 

Which batteries came with it ? Example AW IMR Trustfire and Were did you purchase the mod from if I have this info I will be happy to try and help you, It does get confusing

[MENTION=7599]Laurabolyard[/MENTION] I don't have a varitube so I am unfamiliar with the innards on it. If like many of the mods it has a spring while you were using the nippled batteries the spring could have become compressed enough that it no longer makes a good contact with the non-nippled batteries.

If the varitube does have a spring you could stretch it just a bit in order to create a good contact with the battery.

 

You may want to try one of these.

The new batts are IMR, orig are the stock ICR. There is a spring that I can see (now that it's daylight ), but the unit is plastic and long. Even if I were able to get to it, I'm afraid I would break it!!

So foil NOT a good idea??

Bert, that looks cool!!

Which end + or - are you putting foil on? Is your tube metal?

 

+ end. Tube is plastic

Hi FSORS!!

 

I just bought some copper hot springs that work good too.

 

Oh you should be fine with foil then but the magnets are cheap at home depot and are a bit more elegant solution IMHO

 

If you do get the rare earth magnets make sure they are the silver colored ones the others could explode

 

Lol, I tried looking that up but I'm getting vacation spots instead!! What r they Whis?

 

Dammit fsors, it doesn't sound like I will be trying that!! I did have some thin ones, but a bit corroded. I have others, but too fat. I use them in my reef tanks to hold things to the glass. A bit afraid to try them in this fashion!!!

 

When would in NOT be fine?? Xxxooo

 

If your tube was metal and you were connecting the foil to the + and If the foil happens to slip and touch the body which is the - part of the circ you would get and meltdown short

 

Yours is plastic so no worries

 

Even cheaper at HF if you have one near you
