 Get an extra battery to be sure you always have a charged battery ready to go. The key to extended battery life is to never charge them before they are completely dead, always keep the threads clean on the battery, atomizers, and cartomizers.
The RN4081 Electronic Cigarette Battery comes in multiple color options and has a very smooth drag for easy vaping!

eCig Batteries for Classic (RN4081) model fits several popular model ecigs (i.e. Smoking Everywhere, NJOY, etc...) If your not sure about your model feel free to give us a call or contact us from our contact page.

Battery Tips and Information
  • Clean your eCig battery threads every time you change/refill your cartomizer
  • Clean your eCig battery and charger threads before charging
  • Never refill your cartomizer while it is attached to your eCig battery
  • Take long, soft puffs to get the best vapor production and flavor - Don't take short hard puffs
  •  Never charge the battery before it is dead which is indicated by a blinking LED immediatly and every time you try to take a puff
  • If the LED blinks after you have taken a puff it is most likely not dead, it's blinking because you took too long of a puff
  • Never overtighten the battery in the charger or on the cartomizer - tighten until you feel resistance and that's tight enough
  • Atomizers and cartridges are older technology so unless you already have that technology and like it we recommend cartomizers for best performance

I am still using this original battery because I like the look and feel of it. And I am so happy that I can still purchase them here and I have never had an issue with them. They work great and last a long time.

I have been ordering from Aquavapor for 2 years now and I love their 4081 products. The size of the battery is perfect for me but do not let the size fool you it gives off a great draw.

Rating 4081 battery
Been using these for 4 years and like the classic shape and size. However, I find that the batteries I get now do not last as long as when I first began using them. The older ones would go all day on a charge, but the last ones I got lasted less than half a day before needing charging, and after a month one was completely dead, and the other lasts less than an hour on a charge.

I really like the look of the stainless steel battery. It's quite portable, not too heavy and produces just the right amount of "smoke" for me. Anyone wanting an e-cig and doesn't like the look of a storage tank, might light to try this model...

Not too happy with this. Build quality seems good, and it looks nice. It works well when it works, but the battery does not last nearly as long as others I have. Usually one charge will get you mostly through one carto, but I have to charge this several times to finish one carto. Also I have been having trouble with this not turning on when I inhale. I found that I either have to suck very hard, or if I blow through the opposite end it will start working normally again, but not for very long.

I consider these my old trustees! They are nice to have for a back up, especially since they are small and convenient. I have some that I bought somewhere else a longgg time ago and they are still going strong. I purchased one from AV and had a dud I guess, but they quickly made things right. Great customer service!!!

Rating The 4081 war horse
I started with a 4801 kit. I acquired about 10 batteries. My husband started, then stopped so I got his kit as well. I have been vaping for 2 years. I still have 4 of the original batteries I had - that must be a record. This battery is extremely dependable and lasts forever. If you are brand new to ecigs, 4081 is the way to go. It is automatic, no button to press and looks like a real cigarette. Easy to use.

Have been using the classic RN 40081 ecig for over a year, great ecig for the money. As with all re chargable batteries some last longer than others. I have had good usage periods with these batteries. Before you toss a battery be sure and try a new cartomizer as cartomizers get old they make a battery seem weak when it's really not.

After shopping around for months and being disappointed, I found the AquaVapor RN4081 almost 4 years ago, and have never looked back. The batteries are sleek looking, long lasting, have a very easy draw, and come fully charged. All that with prompt shipping, excellent customer service, and at a great price!

Through my many adventures in trying to find the best 4081 batteries I ended up finding the AV site. I can't tell you guys how happy I am that I did. These batteries last a SUPER long time! I've noticed with many other 4081 batteries (Not All) but sometimes after a full charge with other brands the first few puffs taste well grosse. Not with these! They are wonderful and I love the green indicator telling me "Hey slow down" or "Now I'm dead" This was a great buy and I'm glad I found this site! I will def. be recommending this site to everyone I know who is a Vapor Queen or King as much as I am :)

Rating Best mini option brand period
These batteries are superior to similar models of different brands. The puff count is higher which is what truly matters in a "good battery". Not to mention the size with a cartomizer is not much bigger than a standard cigarette. I would recommend this model for a light or medium smoker, as a heavy would need a couple extra to go a full day.

I have tried a LOT of electronic cigarettes in the past, and I was never thrilled, primarily with battery life. I was given an AV starter kit for a gift. One thing that impressed me was battery life. I can go all day without needing a charge on one of these batteries! The quality is so good, I started my own account to buy a second battery. Soon, I will be buying more eliquid and more cartomizers. AquaVapor converted me to a full time ecigarette "vaper", primarily because I know my battery will stand the test of a long hard day. Thanks, AquaVapor! You have a new lifetime customer.
