Battery Information

By: VaVaVape Staff  |  Revised: 2014

Batteries are a part of vaping, well there are some exceptions, but we wont get into those. Batteries for the electronic cigarette industry come in a variety of shapes and sizes. Regardless of their size, they all have similar characteristics and proper ways of handling them.


A battery is the source of power for the e-cig. There are several types of batteries on the market for e-cigs. Among others, some of the more common batteries are 510, eGo/pass-through and mods. Batteries life is measured in milliamp hours (mAh). The higher the mAh rating, the longer the battery life between charges.


510 Batteries (nano): 510 batteries are a style of battery that are very lightweight and small in size. They are typically referred to as cig-a-likes because they more closely resemble an analog cigarette in size. Since they are so small, their mAh rating is low, which means they have to be recharged more often than other battery styles. The mAh rating of 510 batteries range from around 200-300 mAh. FYI, the name, 510, refers to the threading on the battery that is used to secure the atomizer/tank.

There are two main styles of 510 batteries; automatic and manual. An automatic battery is activated by a sensor that is triggered by the air pulled into the device from a drag on the e-cig. A manual battery does not have a sensor, instead it is activated by pressing a button on the side of the battery.


eGo Batteries: An eGo battery is a slightly larger battery as compared to a 510, but with the increased size comes increased battery life and power. The mAh rating of eGo batteries ranges from 450-2000 mAh. The majority of eGo batteries are manual style batteries that are activated by pressing a button on the side of the battery.

eGo batteries come in three variations; fixed 3.7v, variable volt (vv) and pass-through. A fixed 3.7v eGo provides 3.7v to atomizer and cannot be adjusted by the user. A VV battery allows the user to adjust the battery output voltage provided by the battery to the atomizer. Generally speaking, a lower voltage setting (3.2v) provides a cooler hit and provides the greatest battery life before needing to recharge. A higher voltage setting (4.2v) provides a warmer hit and typically it will provide more vapor production. Higher voltages will decrease the battery life before needing to recharge. A pass-through battery can be either a fixed 3.7v or a variable volt. The key feature of a pass-through is that it can be used while it is plugged into a USB plug or a charger.

At VaVaVape, we offer two styles of VV eGo batteries; twist and a tri-mode. A twist eGo allows the user to adjust the voltage setting by turning a dial on the bottom of the battery. Typically, the voltage range is from 3.2v - 4.8v and it can be set to any point within that range. A tri-mode eGo battery allows the user to adjust the voltage between three different power settings by pressing the fire button three times. The three settings levels are 3.2v, 3.7v and 4.2v.


MOD Batteries: Okay, now we are getting serious. MOD batteries are batteries that are used in an Advanced Personal Vaporizer (APV), also referred to as a MOD. APVs allow users regulated power that can maintain its power setting through the battery's life between charges. See below for more information on APVs. MOD batteries are removable from the from the device (the APV) and placed on a charger. MOD batteries vary in both overall size and mAh ratings. Common MOD batteries are 18350, 18490, 18500 and 18650. These numbers represent the actual measurements of the batteries. The 18 represents the diameter and the last three numbers represent the length of the battery, both measured in millimeters. Depending on the brand and size of the battery, the mAh ratings will typically range between 800-3500 mAh.


So not all batteries are created equal. You must take special care of what you are using to generate the power you need. Batteries can be dangerous if not handled properly. There are batteries out there with built in protection (most do not), but sometimes even these fail. It is important to follow all safety precautions when handling and charging your batteries.

  • Keep your battery terminals clean - it can cause a short or a poor connection
  • Don't charge your batteries unattended - they can catch on fire if safety features fail
  • Don't over tighten your battery on the charger or tank - you can damage the threading
  • Clean out any juice in the battery terminal before charging your battery - it can cause it to short
  • Don't drop it - it can be damaged
  • Don't carry in pockets or a purse - It can snap in two or if not turned off or locked, accidentally fire
  • Don't carry loose mod batteries in your pocket - they can short and vent causing very serious bodily harm


Mechanical mods are intended for use by advanced users. You are using one at your own risk.

When using mod batteries in a mechanical mod there are a couple very important things to remember. Number one, safety. You have to know what resistance coil you are about to fire on your mod or you risk battery failure. Trust us when we say it, you don't want this to happen. Your coil could be something rediculiously low (.25 ohms), assuming you built it yourself. Yeah it may work, but you'll be hard pressed to find anyone 'in the know' to recommend running something this low. With that low of a resistance, you are demanding a lot of power drain from your battery, so be sure your battery can handle the power demands you are requiring.

In addition to safety, you need to remember that without a PCB board, you will not be warned that your remaining battery charge has dropped below 3.3v. It is up to you to know when to charge your battery. Now you're probably thinking to yourself, why does it matter, when the battery is dead it's just time to charge it. Well, that is not correct. If you drain a battery all the way down, that battery is done. Once a battery's charge drops below a certain point, it cannot be recharged and your battery is now a paper weight. Don't worry about this too much though, it will become obvious to you after you use your mechanical for a while.
