How to put a nipple onto a battery

[Darthpistachio]

Well aside from sending the battery to a plastic surgeon to correct it's anatomical problem there is a simple easy way to put a nipple onto a nipple-less battery.

Well it needs clarification first - all batteries have nipples - but the Reo looks to me was designed for the type of battery whose nipple protrudes out of the top - which is what the slot is for in the plastic of the top section of the Reo grand.

Now I have some Panasonic greys and Samsung Pinks here and although they have a nipple -- their nipples are flush with the top of the battery.

My particular Reo grand was having a hard time making contact with the recessed nipples and the subsequent hits took time and were not very hard - the contact was at the very limit of my particular spring - and I have only two AW IMR with the more pronounced nipple and 6 other batteries with flush nipples.

Not wanting to have to stock up on further more batteries I ordered some of these from ebay:

Neodymium disc magnets 6mm diameter x 1mm thick

this is the battery with it's flush nipple



This is one of the disc magnets



and here is the magnet fitted..



It now slots into the correct place fine - the magnetic force of the magnet is nowhere near strong enough to pull on the firing spring metal and cause errant firing and now it reduces the throw of the firing spring for these batteries by a full 1.2mm which is quite a lot -

Reo now hits hard and faithfully every time with these batteries..

Hope this is useful to some of you

NICE!!!!

battery pr0n at its finest

WHAT?!!?!??!?!??! He said nipple

DONT use magnets, just dont

I was doing the same trick on a provari. Worked fine for a few weeks, even used superglue on the sides of the magnet / battery.

But the magnets over time lose their grip, mine moved and made a short (collapsed the spring and tube got REALLY hot). I was lucky that the board wasnt friend

You are way better off soldering / welding your own nipple to the top of the battery, at the structural level it becomes a continuous unit

This is a Panasonic ncr18650pd I'm using right this second on my REO, its re-wrapped and a tad dirty from using it on some other devices that leak, but you get the idea:

Duh. This is easy.

Kinky, mine prefer clamps.

Even tho Robert says no, I'm doing this same thing. Little Oxgard between the bat and the magnet, little on top of the magnet. Works like a dream. Nice strong hits.

The way the Reo is built there is really nowhere for the magnet to go, plus the firing pin seems to be non ferrous, so I'm not worried about it sticking to the magnet.

I don't want to speculate about probability, but my imaginings of the structure allow for the magnet to make contact with the door.

Now. A custom firing pin, designed for exclusive use with flat buttontops . . . this I will be making soon.

I tried using a magnet on some of those flattish-top Panny's a while back. It worked for a while, but one day the magnet got dislodged in such a way that it caused the firing pin to stick, and I had to quick yank the battery out of there. So they went in a drawer. I wouldn't try it again without solder.

If your Reo shows up in an XRAY like in your avatar ian74...then gotta definitely say...You're doing it wrong!!!

Or...you give a whole new meaning to the word "Vooping"

Your pic and avatar are funny as hell

Why do I have to read posts with "nipple" in the topic? Hmmmm.....

Will JB Weld work? I did use loose magnets, in REOs, on some "flat tops" back in 2010. Never had a problem but maybe I was lucky. I ordered several size magnets and used the one that fit the best.

I have some "flat top" panies I ordered by mistake. Luckily they do well in Woodvils.

Looking at my Grand right now, the magnet would have to travel so far the it would stop touching the positive post of the battery before it hit the door.

Plus, the cutout in the top delrin on mine is lower than the height of the magnet, if that makes sense. The magnet I'm using actually fits almost perfectly in the hole that is milled out for the firing pin. Basically the magnet is going nowhere fast.

I'm with you on this. I had the exact same batteries and what appears to be similar magnets to the OP's and I didn't even get a day's worth of use out of my first REO before I witnessed the dreaded "orange glow" of my spring melting.



Of course, it was a "Tumbled Raw Aluminum" Grand, which I suppose conducts voltage easier, but I still wouldn't use magnets in any REO for my own peace of mind. However, if you want to "walk the razor's edge" that's up to you.

Thanks,

OK - taking all your advice re: magnets on board - I'm intrigued by the soldering of a nipple onto the battery but I have to ask what are the safety issues with heating the top connector of the battery up to the point where you can get satisfactory solder flow and adhesion? SURELY that isn't safe in itself??

I'm just careful doing it, put the soldering iron vertical and close but not touching the battery, bring the solder to it and a few drops onto the battery does the trick

then you can gently scrub the iron just on the top of the solder if you need to tweak the shape

A pack of smokes cost me more than an AW IMR I smoked 3 packs a day so 3 batts cost less than one days smoking. 3 batts looked after will last 2 plus years. I just don't get it buy the right batts and be done with it simple eh ?

Negative...JB Weld will act as an insulator once dry...they are usually soldered down

unless it's just a personal matter of not wanting to support Andrw wong with my money? I mean, he is a middle man (that does some great tweaking to other people's cells)

And by the days account, saving half the price in batteries allows for more gear (and eventually more REOs)

AWs: Great batteries, nasty pricing
