Are These Batteries Safe To Use?

I bought my Sigelei 100w Plus a few days back and ordered 2 Sony VTC4's on my same order (I'm confident they're legitimate, I've bought some before) to be able to marry them together and use them with my Sigelei. Upon receiving the batteries, I labelled one A, and one B and put them into my charger at the same time (charger was off, put both in and turned it on), one battery is slightly more charged than the other (it's 2/3 bars, while the other is still 1/3). I'm a bit worried about using married batteries, I understand rotating A and B in my Sigelei and charger but will they be the same charge when they're done? They're new batteries and they both went on at the same time yet one of them is charging a little bit faster.

When both of the batteries are fully charged, will they be safe to use and cycle accordingly? I heard about if one battery has even a tiny bit less, the batteries will take an uneven load and it will make it risky. How do I ensure that these batteries remain married?  

Hi folks,

I recently purchases a Sigelei 100w box, and got the purple Efest batteries that the vendor recommended.
I'm using this with a KangerTech Subtank Mini.
It's currently set to 42W - 5.0V, and the resistance it shows me is 0.6 ohms.

I have some questions about my setup.

- I read some reports that these batteries have different specs than what is reported, and it could potentially be dangerous. What should I do to be safe? Is there a max W/V that I can set it to?
- I have a TrustFire TR-001 charger (output: 4.2V / 500Ma). Can I charge those batteries with that? I read the charger supports 18650 batteries, but I'd rather be sure...
- If the charger is no good, any recommendations of what I should be using?

Thanks a lot!  

I just bought 2 18650 Batteries today. I realized that on one of them, there is a small scratch. Is it still safe to use?  

Hi Guys,

So I originally had a nitecore i8 charger that I used to charge 8 x 18650 batteries. After using it for a few days I started noticing that it made a weird ticking noise and got VERY hot on the bottom. Needless to say this made me quite uncomfortable.

So I exchanged it for a Xtar VC8. So far it’s been amazing. No ticking or weird noises and it doesn’t get hot. It also comes with a nice screen that shows you some details about your batteries. This is what leads me to my question.

I noticed when charging my batteries most of them show as roughly 3.7v but others show as 4.1v. Also the longer they charge the higher the number goes. Is this normal? Sorry I’m a total idiot when it comes to batteries and voltages etc. If anyone could clue me in i would be very great full!

Thanks  

I am interested in setting up an Arduino charger for my vape batteries. But the charger I want to use, an Adafruit bq24074 solar charger, does not support nominal 3.6V batteries. And basically all the Mooch approved batteries are nominal 3.6V. So, which 3.7V batteries are considered fairly robust for high current, vaping purposes?  

Okay so I did look this up and it appears that other people have mentioned this specifically with sigelei mods but I didn't see any that were more recent. I look at my mod to see what my batteries charge looks like to see if I need to go ahead and change batteries and I swear to God the thing starts jumping around as though the batteries are charging themselves and then going back to the 40%. Apparently that's a problem that the mods have and isn't something to be concerned about but it freaked me the heck out. They're doing just fine now that they're in their external charger thingy but I just want to make sure that that's not a sign of something going wrong with the batteries that it's just my mod being weird I've checked the connections and everything to make sure it was clean and that the batteries were fine and not dented or unwrapped and everything looks good. I just need some assurance that the batteries were not like failing or that a regulated mod would shut itself off if batteries were jumping around like crazy in reality if that's even possible
For clarification it was doing this when I was not firing it  

Hey all,

I've been using the Intellicharger I2 for a while, and recently I've noticed it's taking a long time to charge batteries. Keep in mind I realize that the Amp output is distributed across two batteries, etc, but I feel as though its time for an upgrade.

I regularly use Samsung25R's and occasionally VTC5's, (18650) and I was wondering what your opinions are on the best charger I can buy. The criteria I'm looking for ideally a

External transformer
Fast charging time
LCD screen
Ample venting
Autostop cuttoff when batteries finished

Thank you in advance!  

Is it safe to use the vaporesso revenger (built in batteries) and the vaporesso revenger mini (lights up) after owing it for three years? It seems to have kept 3/4 battery charge and I have not used them in a year and a half. I ask because I’ve read older batteries can be dangerous to use if they have low voltage or something.

Also is it safe to use Sony lithium ion batteries after 2 1/2 years? Their volts was at 3.6 when I started charging them. I haven’t used them in a year and a half, but I did charge them once during the year. Using them in arrow sense mod.  

Herro!

So, I always used to use mech mods from about 6 months to a year and a half into vaping. For the last 6 months I've been on regulated (iStick 30W and 50W).

When I switched to regulated I retired my mech mods and 18650 batteries to the closet. I made sure they were all around 50% charged because I heard from someone on here that was the best condition to leave them.

Well recently I've had this curiosity to try them again, only for at home use, mainly for the novelty of it.

So, my question is, what will I have to do to revive these batteries? Are they safe to just throw back on the charger and use when fully charged? Or are they not safe to use?

Batteries: 4 Sony VTC 4's (all were acquired about a month before I stopped using mechs), 2 XTAR (Sony) VTC 4's (about a year old now) , 2 MXJO 2500mah (20A LG's) (about a year old now).

Let me know! Thank you!

Vape Happy,

LONG STORY:
Following a previous thread (Question about battery and coils (Swag II)) I have been using Molicel P26A with my two Swag II's for a couple of months.
I purchased four batteries but I have been using only two of them. I always keep them in the Swags, since I use the Swags to recharge them. Practically I keep one of the Swags under charge while I am vaping with the other one.
I find this routine very convenient however I am wondering if that is the best way to recharge them. While a the begining both batteries were working quite well until they reached a 20% level, now one of them seems to be very weak as soon as it reaches 50%, and for that reason I have decided that it was time to replace it.
The other one is still Ok.

SHORT STORY:
Is it ok to recharge the P26A's with the Swag II's or should I use an external charger? Would an external charger significantly improve the life of the batteries?
Also, can an external charger fix a battey that seems to have lost 50% of its capacity.
