A "Fail" grade does not mean the battery fails, vents, or bursts at that point! A Fail grade only means that the battery has risen to a temperature that risks venting if continuously discharged. When vaping, we pulse the battery. You can set a power level, or use a coil, that exceeds the settings below. But if you do you might be risking battery damage or worse if you have a problem (a regulated mod autofires or a mechanical mod's button breaks or gets accidentally pressed in a pocket). This table is for those who want to know the actual battery rating and how hard they can push it while still retaining a safety margin against a mod malfunction. If you understand the risks, Ohm's Law, and battery safety, you can exceed the Fail grade settings. If you are new to vaping or want a good safety margin until you've learned more about battery safety, then let the settings below be your limits when vaping.

Mfg CDR = The continuous discharge rating (CDR) given by the manufacturer/reseller. My CDR = The continuous discharge rating (CDR) assigned by me based on my testing. Red = my rating is below the manufacturer's/reseller's. Green = my rating is above the manufacturer's/reseller's. Max Amps = The maximum continuous discharge current you can draw from this battery without exceeding my 100°C safety limit. Much higher than this and you risk cell venting or worse in case of a mod malfunction. This can be considered its "pulse" rating since it is the maximum you can draw from it while vaping but still have a bit of safety margin in case your regulated mod autofires or your mechanical mod's button gets stuck or gets accidentally pressed in your pocket. You can often significantly exceed this rating when vaping without overheating the battery but you increase the risk of battery venting in case of a problem. N/A = Not applicable. The cell shut down, stopping all current flow, when discharged at these levels. The cell reset after several seconds. Caution: You are responsible for your own safety! This table is only meant as a first step for you to use in narrowing down the best choices for the way you vape. Do not use it as the only source of information when picking a battery to use! This is especially true if you intend to use a battery at over 50% of its continuous current rating. The conclusions and recommendations I make here are only my personal opinion. Carefully research any battery you are considering using before purchasing. I am not responsible for any damage or injury sustained by anyone using this table to select a battery.
This table assigns a grade of Pass, Caution, or Fail based on the battery's maximum temperature and the damage sustained during a continuous discharge at different current levels, from 5A-40A. If chain vaping you can raise the battery temperature a lot, accelerating the aging of your battery. If there's a problem with your mod or the button gets accidentally pressed (for a mechanical mod) then continuous current is drawn from the battery. This can heat it up to a dangerous point depending on your coil resistance. This table does not take battery performance (capacity, voltage sag, etc.) into account, just safety. The grades are defined as follows: Safety Grade
Battery Temperature
Pass
45°C-75°C 113°F-167°F
Slightly reduced battery life possible if chain vaping, good safety margin.
Caution
76°C-85°C 169°F-185°F
Additional battery damage with each time it reaches this temperature, reduction in the safety margin in case of mod malfunction.
Caution
86°C-99°C 187°F-210°F
Significantly reduced battery life if it reaches this temperature from chain vaping or very high power/low ohm builds. Significant reduction in your safety margin in case of mod malfunction.
Fail
>=100°C >=212°F
Significantly increased chance of battery venting and possibly bursting if the mod malfunctions ("autofires") or a mechanical mod's button gets accidentally pressed. Use caution if chain vaping with a build, or a wattage setting, that results in temperatures this high.
Damage Fail
n/a
Significant damage to the battery occurs even though the temperature should not be high enough to worry about cell venting. Use caution though as the batteries are being used beyond their ratings.
