Guide to Batteries.


Today i am bringing you a guest post from Baditude over at 

http://www.e-cigarette-forum.com/forum/


A guide to all things batteries, this is a great guide, easy to 

understand and a must read for everyone. 




As mod users, we depend heavily upon batteries. To assist novices to choose which battery to use in their mod I have written this guide. Our choices are IMRprotected ICR Li-Ion, and a new class of Hybrid batteries.

High quality IMRs are currently recommended in place of Protected Li Ion for all applications. (reference -Rechargeable Batteries)

IMR (Li Mn) batteries are the safest batteries available to us for vaping. They use safer chemistry, so they don't require protective circuits like ICRs do. They have higher tolerence to stress, and although they may vent during failure it is less likely to be as dramatic as a ICR. Should protective circuits fail in ICRs they can vent violently in flames and possibly explode.


  • High Quality, Brand Name Batteries. Batteries are not created equal. Mod battery experts recommend the following brand name IMR and hybrid batteries:

  • Lower Quality Brand-Name Batteries. Trustfire, Ultrafire, and Surefire are a second-tier name brand battery in terms of quality and safety. Not recommended.



  • ​Generic Batteries. ​Not recommended. Seen at Amazon & EBay at cheap prices or thrown in for free in a kit when you purchase a mod made in China. These are unknown batteries of unknown quality by an unknown manufacturer, and not worth the risk using in your mod. Never assume because they were included with your mod that they are safe or the correct battery to use.


  • Be wary when shopping for batteries online. Unprotected ICR batteries should NEVER be used in a mod. I recommend buying only the batteries from the list above, paying attention to model numbers.


  • If uncertain about the quality or type of a battery, don't buy or use it. Do not use over-the-counter batteries like those from Radio Shack, etc. Buy only from trusted e-cig vendors. Many use RTD Vapor AW Batteries. Use the type of battery that your mod calls for. For example, Provape recommends using only AW IMR button top batteries in the Provari; using magnets on flat top batteries will void the warranty because this is an unsafe battery practice.


  • Battery Chargers. Get the best charger that you can reasonably afford. Statistically most battery incidents occur during the charging phase on a charger. PilaXtar, and Nitecore Intellicharger ​are the highest recommended brands.


  • Always use safe battery practices and common sense with all batteries. Even the safest battery available to us can fail. IMR battery failure Most battery failures are the result of rapid discharge, either from the fire button inadvertantly being pushed for too long, or the battery being shorted from metal objects (keys, change, etc) completing the circuit when carrying a battery in a pocket or purse. Use Battery Cases. Do not stack batteries.


  • If you are using sub-ohm coils in an RBA/RDA, it is extremely important to use the highest quality IMR battery. Coils < 0.8 ohm require an IMR battery that has a maximum continuous discharge rate over 10 amps​. This is extremely critical. Sub-Ohm Battery Chart

PROTECTED or IMR BATTERY: ​Which is best for your application?
IMR Li Mn. Lithium manganese batteries. Also called "high drain", "safe chemistry", "unprotected".


  • These are used in regulated mods that use buck boost circuitry to achieve variable voltage-wattagebut they are now also recommended for single voltage mechanical mods as a safer alternative to protected Li Ion batteries.


  • This class will have less capacity in mAh rating compared to protected batteries, but are superior when maximum load current is required, such as in regulated mods, mechanical mods using a Kick, or using an RBA. Why High Drain Batteries?

Hybrid batteries. 
  • New mixed chemistry batteries that are both safe chemistry/high drain and extended capacity in one.


  • A good choice for applications that demand both maximum load current and longer battery time. Can be used for either mechanical or regulated mods. Some of these have 20 or more amps continuous discharge rate which are ideal for sub-ohm.

Protected ICR Li Ion. Lithium ion class batteries, also called "protected batteries".

  • These batteries use a built-in protective circuit because they contain volatile chemistry that can become unstable quickly when they are severely stressed. Circuit failure can lead to battery failure, venting violently with flame in an event called thermal runaway. No longer recommended for use in a mod.
