Are my batteries dead?

[CoughingBad]

Got these MF 78mm batteries maybe about 2 or 3 months ago (got 2 in jan and 2 in feb not sure which ones is which).

Anyways, yesterday two of them, fully charged, started having very hard draw and eventually just not vapable. Are they dead, any trick to revive them? Or is it just how long a battery will last?

 

[DeeLeeKay]

Sounds like they may need to be cleaned. Take a pin and clean the little holes on the battery threads.

 

[CoughingBad]

Thanks Dee, i tried that. And i think it worked a little, because its now vapable but still have a very hard draw... how long do your batteries last?

 

[DeeLeeKay]

You may need to just give them a good cleaning. They last about 300 recharges. Try a little alcohol on a tissue and go around the threads and clean the holes really well.

You can also pop the ash-cap off (carefully), and make sure nothing's clogging it.

Did you possibly get juice in the battery? There's a method out there for using silica gel to possibly revive them.

They should last longer than 2-3 months. I've had two of my batteries on rotation for over two months and they're going strong.

 

[DeeLeeKay]

The juice will build up and into the airway holes on the threaded part of the batts. My son in law complained about the same thing. We cleaned them really well and they worked good as new.

 

[CoughingBad]

hey it worked the rubbing alcohol trick, thanks dee!! But just one of them, the other one is still dead. Im charging it again and see if anything different.

frick yeah most likely i got juice in them its totally possible. what is the ash cap?

 

[DeeLeeKay]

The ash cap is the hard plastic cap at the end of the battery that lights up.

 

[CoughingBad]

Ahhh should have known.. but i never thought that part of the battery has anything to do with how the battery works. Isnt it just for led purpose?!? i learnt something new everyday......

Its an opening into the battery aswell. There a thread on model spec that states you can pour a drying element in, to soak up juice. He used the stuff in the little bags you get when you buy a new pair of shoes.. Soaked the juice up.

Nice tip, Michelle, but note that the poster only succeeded with one out of two tries.

 

[MichelleDen]

Ya i saw, worth a try if its comepletely dead. I got juice in my reddie, but was able to get it going again, by sticking a small piece of folded paper beside the connector and soak it up. Sat it on the table to next day.. little juice had run out.. Wiped it, and worked again..

 

[CoughingBad]

okay the other one is really dead

Thanks michelle for the link, it sounds so complicated i will have to read again to see if i can figure it out. still dont know where to get those silicone thing. well i just woke up, brain not functioning properly

well at least i revived one, better than nothing. THanks everyone!!

You could probably use plain old epsom salts from the drug store, bake a small amount in a 400*F oven for an hour to really dry them. Just to dork you out a little, Epsom salts are MgSO4 (magnessium sulphate) in the presence of water, they absorb it to become magnessium sulphate heptahydrate, meaning that each molecule of MgSO4 can absorb 7 molecules of water. They will likely leave behind lots of other stuff, but work on the same principle as silica gel.

Basically you just put the salt or silica in the battery as much as possible, seal it in an airtight container with more of the salt/silica, and leave it vertical so as much juice can drip out as possible, thats it, it absorbs the juice, or it doesn't....

Get a new pair of shoes..... Perfect excuse for women.... But honeeeeey i gotta gettem, otherwise i waisted all this money on batts... haha

 

[starsong]

LOL Michelle. I have a bad habit of keeping shoe boxes. Never know when you'll need a box. So I've probably got a few of those packets still in them. Gonna go fish them out to save just in case. Thanks for the tip.

Analog, that was more nerdy than dorky.

I've notice my BMF batteries aren't lasting quite as long as they had been. Although when I first got them they lasted longer than everyone SAID they should. I could vape all day long on one charge. Now they don't quite last all day. They still function properly though. I've had them about one month

 

[starsong]

Wow you got lucky, or don't chain vape. My use varies... one will last the whole work day because I'm only using it occasionally. But once I get home I rarely set it down except for meals, so that one will only last ~3 hrs. Still using the one I got mid-January and there hasn't been a noticeable difference in battery life yet. (knock on wood)

 

[Frick]

I think there's a slight 'break-in' period. My new white battery is definitely lasting longer than any of my other three 'broken-in' batteries. I remember getting close to 4 hours when they were new; now they're good for 2-1/2--3 hours.

 

[Gardner808]

I have noticed that as well. I am glad I have 3 batteries now. It has been a close thing a couple of times when I thought I would be without a battery to use. It is certainly making me consider adding one more battery as my failsafe.
