How long can I expect my UltraFire 18350s to last?

[icemanx3]

Hi all. Gotta a battery question here. My RoughStack from madvapes came with two UltraFire 18350 1200mAh 3.7v batteries (those blue ones). I've been banging on them non-stop all day since late October and I couldn't tell ya really if they are showing wear and tear. I was wondering, does anyone know the approximate lifespan of these? I'm sure there would be a certain amount of charges these could go through. I think if they are slowly aging, I could possibly also slowly lose the full vape experience (as far as battery power goes).

Thanks so much!

Are you noticing a difference in your vaping experience?

It has been my experience with rechargeable batts that you start noticing that they are not holding a charge for as long.

Their performance when freshly charged is initially the same as new and rapidly falls off OR they don't stay charged when not being used.

You could get a meter and take a reading off of them freshly charged and see what you get and then after you have used them for a few hours and after you have let them lay around unused for a few days. I am definitely not an expert in this matter except that my livelihood depends on dependable battery power.

Great advice. I will try looking at the voltages. You know, I think I do notice maybe really good power at first, for about 30 mins. After that, these do still last through the day but maybe not as powerful. I think initially I would use one of them ALL day, and the following morning swap. Now I've been kinda swapping mid day as routine.

You know when you've got a good charge when you first put the battery in and your atty is hissing and popping like mad!

Thank you!

The other variable in this is the condition of your attys. They do start to not perform as well eventually.
I have some I have used for months but when I start off with a new one, I sure notice the difference.

Then there is that phenomena of our tastes changing the longer we vape...hence the constant search for the next "favorite" e-juice...lol.

They are rated @ 500 charges, Your personal mileage my vary.

Thanks all! I do keep my attys super clean...but agree there's NOTHING like pulling a brand new one out and banging on it for the first time!

Java, awesome. So I've charged these at least 75 times, + - 10 charges I would estimate (I got them at the end of Oct). To me, even having them charge 75 times each seems like a good value if they were starting to head south. Like I mentioned I don't know if they are losing their umph, but if it's a gradual thing...well, you know I just couldn't have that getting in the way of my vaping

I think I am going to try testing out my third 18350 battery that I was keeping on hand as a back-up. I've never used it so I'll try some experiments.

They will lose total capacity over time. I believe the specs say no less then 80% of original.Those are China made batteries also they tend to be less then honest on there data sheets. Nothing like Japan made batteries where they have the truth on the data sheets. But if by umph you mean they dont last as long between charges thats normal wear for these. Shouldnt effect vaping other then having to recharge sooner.
