How Long Do E-Cig Batteries Last?

I remember choosing my first e-cig off of the general idea of vapor production. I wanted something that made clouds of vapor… and everything claims to do just that. One thing that isn’t quite as easy to find out is an idea of how long each model’s battery life between charges actually lasted. You can read review after review and see people claiming totally different time spans for how long their e-cig would last between charges.

This post is an effort to give people a ballpark idea of how long some of the popular (Non-mod) e-cigs will last between charges.

Does battery life matter? Of course!

The battery life is the most important thing to me personally. More Battery life = More Freedom. You don’t want to have to worry if you are going to run out of battery while you are away from your charger. Once that happens you start behaving pretty weird… You start cancelling nights out with friends because the dinner+movie+drinks will outlast your battery, and you will eventually succumb to bumming cigarettes off someone. You don’t want that! It is very important you know how much time you have with your e-cig.

Another aspect

Typically the batteries in e-cigs have a lifespan of around 300 charges give or take (seems like less by the way). If you have an e-cig that you only need to charge 1 time a day, then it will last you around 300 days. That’s a long time.

When I started out I had the 510.. I went through the batteries multiple times a day and they died within 2 months. This meant that I really needed something with more battery life.

I have never purchased an e-cig before, how do I know how long any will last me?

In short, you don’t. But, luckily we do have general averages.

In this little experiment I am going off a general average of the eGo model e-cig. It’s stock batteries are rated at 650 milliampere-hours (mAh). You can think of mAh as the capacity of electricity that a battery can hold.

(For those of you who don’t care about the details, skip ahead!)

After scouring the forums it looks like 1 eGo battery @ 650mAh generally lasts someone about 6 hours.

The math (nothing fancy)

If you take 6 hours (The average battery lifespan of the eGo between charges) and convert it to minutes you have 360 minutes. Divide  360 minutes by 650 (The mAh of the eGo) you get .55mAh per minute. This would mean someone who goes through an eGo battery in 6 hours is using an average of .55 mAh per minute. Once you know how many mAh you are using, you can apply it to any battery and figure out how long it should last you.

*Note- For all of you die hard tech guys, I know, atomizer resistance and other issues change this, but like I stated, this is a ballpark idea for people.

I made a simple spreadsheet to document some typical e-cig models out there and their batteries.

Here is a snapshot of the data:

E-cig model on left, mAh on far right, and hours it would last in the middle.

And here it is as a chart for a visual comparison: (Click to enlarge)

Pretty interesting stuff. I wish I would have seen something like this when I was first looking around. Just seeing all the models mAh in one place is helpful.

Hopefully this information will be useful to both first time buyers and current e-cig users looking to make another purchase.

    I don’t believe many people are satisfied with their first (few) purchases because this information is not available. The most common tier of products available seem to be inefficent and expensive, and I feel they are oportunistically taking advantage of people’s desire to quit or cut back their smoking. Instead, as in my case, bad purchases probably delayed my efforts to quit for several years. I was convinced nothing would work and gave up – as usual, many times. Then I discovered a REAL e-cig. HOLY SMOKES! I can do it with this! Freedom at last. I am still upset with the amount of money and the emotional distress caused by not having more knowledge from the beginning.

    It’s common to get a burnt taste with a fully charged battery, I am sure you’ll notice that most when your re-using a carto you were already vaping, seems as though this is because of the peak voltage and output is heating the filament to prevent complete wicking, I solved this by refilling my cartos right after I flat a battery.

    I wish i could know more about the battery life in terms of holding a charge. how many charges are they good for when does the charge decline etc but i know that a lot harder information to get as you would have to test each battery and just one will take a long time (normally this information is included with a device or battery information but the lower priced battery’s basically all the types you have posted (non mod Chinese battery’s) If you could find this information it would make a great post.

    The first e-cig I got was too mahch of a problem. No really, it was like .5 mah and died instantly. One of those “micros.” This information should be useful to anyone needing to know how long a typical battery will last. My eGo has been a solid choice as far as battery life is concerned. Although, I’m sure an upgrade is in order soon enough. What are some of your experiences with Provape?

      I own a ProVari and in my opinion, it is the best ecig on the market. The company (ProVape) is a good company to deal with, their customer service is top-notch, and their shipping is fast. I have nothing but good things to say about them!

    Yes, having this in the beginning would have been a BIG help. I have been vaping for a tad over 4 months and my original 510 bats are still going strong. I do not use them every day tho. I use my eGo most of the time when I go out and about. Plus I have 3 mods to use at home. So, I spread my usage between all of them. It is still nice to have the 510 for times I want stealth. I do have a PCC to use and I charge it fully if I am going to go out with my 510. I do have to say that my eGo tank is by far my fav. I bought 2 1000mah batteries and then bought 2 tank atomizers. I use cartomizers as well. I wanted large batteriesw so I bypassed getting a kit with the smaller batteries.

    I am happy camper now!

      Sounds like you’ve got some serious gear. That’s part of the fun of vaping, in my opinion, is all the cool new devices and gadgets there are to try out. Glad you like the post!

    I get about the same out of my 650 but what about first time charging, is it really important to charge for 8 hours? My first 2 I did this with and they are holding good. My new kit after doing this seemed to have a brunt smell and when I contacted vendor they told me I probably overcharged it????? Remove it as soon as the green lite comes on or what???

      @Steve – I have done it both ways and had pretty similar results. With about half my eGo batteries I’ve charged them overnight the first day I received them, and with the other ones I vaped them immediately until they were dead, then charged them. Obviously, I recommend charging them the 8 hours when you first get them simply due to the fact that the manufacturers typically recommend doing so, BUT I haven’t seen any bad side effects in my own personal experience with using them right out of the box without charging them up. Either way, any eGo battery SHOULD perform well whether you take that step or not.

      Now, on the subject of the burnt smell… If you are getting a burnt smell from your BATTERY (not the atomizer) and there is no burnt flavor, that to me sounds like a faulty battery. I would immediately contact the vendor and ask them to replace it (most will without even asking many questions). I would also stop using it immediately, as faulty batteries are no joke. I believe just about any ecig battery that is being released currently has overcharge protection mechanisms in place to prevent damage to the battery if left on the charger too long, so the vendor telling you that it probably got overcharged is a total cop-out.

      If the vendor you purchased it from doesn’t send you a replacement battery immediately, after hearing it has a burnt smell, there is a serious problem there. Contact them again and ask them to replace it. If they don’t, I would avoid purchasing any products from them in the future.

      Hope that helps! Let us know.

    I agree with what was written within the article; that the information given would have been very helpful to me when purchasing my 1st e-cig.
    Since April 2010, I have several versions of batteries but my Fave has to be, My Pink Riva!!!! Purchased July 4th 2010, and it lasts approx. 8 -10 hours before needing a charge. It is convienent and, Oh So Pretty!!!

    I think I’m going to enjoy this site, but I would enjoy the prize more heehee!!!!
