First mechanical. Spring question

[Kiolbassa]

Got my first mechanical in the mail today, sigelei #19. I've been holding off on the mechanicals because they just seem too simple and plain compared to VV/VW devices. Well, I was completely wrong. This thing kicks ... and is freakin beautiful. Used it with a Protank and an 18650 and WOW. I was really impressed. What really impressed me was the battery life. I vaped the hell out of this thing all day. I was about to get off work and decided to check the voltage and low and behold it was still at 4.1v. I was expecting at least 3.7 for using it all day and heavily. The only thing I'm unsure of is how tight to tighten the battery against the spring. Should it be compressed? or should it just barely make contact?

You want it to be good and tight, just not so tight that it is hard to get apart. The battery being snug is going to give you a good connection and not harm anything.

So it's ok if the spring is compressed all the way?

 

[AttyPops]

Is it a "hot spring"? Part of the "safety" features?

BTW...battery life can be a bit lower with all-mech. That's because it's running at max amps for the given coil ohms at all times. Regulation would reduce the amps... if A) Efficient and B) lower than average battery voltage...thus extending the battery life. Some eGo units do this, for example. So do super-minis to extend vaping time. The trade off is lower voltage.

Man, I wish I could tell you. It's gold and looks like my Vamo spring, if that helps.

Your question can't be answered properly then. Ask the vendor.

The spring most likely is a "hot spring", and as Atty Popps said is a safety feature. Should a battery develop a hard short and get hot, the spring will collapse to break further electrical connection and hopefully prevent a battery catastrophe.

If it is still gold or silver colored, it's fine and hasn't collapsed yet. If darkened or tinged to a darker color, it may have already collapsed and needs to be replaced. Carefully inspect your batteries to ensure they look normal, too. Its a good idea to measure battery voltage coming out of your mod and when they come off the charger for unusual voltage numbers.

If it appears ok, you can pull and stretch the spring out more to increase it's length for a better battery connection.

i think it's a hot spring too.....put a little bit of sandpaper to it, if it changes color, it probably isn't going to though, as most springs are made solid.

The #19 is a bottom button, so there is a 99% chance that it does not have a functional hot spring. Yes it would allow the battery to drop away from the positive connection ......... if you can get your finger off the button fast enough to prevent thermal runaway. (which I doubt) The spring is insulated and not part of the electrical ckt with most bottom buttons.

Personal choice of course, but I won't use that type of switch without a 2 cent fuse under the battery. OH, and a hot spring is never functional if it is fully compressed.

I figured the spring is useless when fully compressed, but it seems that's the only way I can get enough current to fire up the atty. I'll definitely look into the fuse since I've already shorted it and it got hot QUICK. I did do the roughen up the magnet button and the battery terminals which did help for more consistent firing. I was looking into the Nzonic head for it which doesn't have a spring at all so I guess some fuses seem like they'd be a wise investment. Thanks for all the advice!
