What does IMR mean? How do you know if your batteries are High Drain or not?

Hi

As you can tell....I'm a newbie! Your thoughts would be greatly appreciated

Thanks

IMR is just considered "safe" chemistry high drain batteries, but unsafe use of any battery can be dangerous. Safe use of any proper battery is...safe.

I = somehow stands for "lithium".
M = means that manganese (Mn) is a major component of the battery chemistry, making it safe chemistry.
R = indicates the battery cell is round.

I = lithium battery.
C = cobalt is the major component of battery chemistry.
R = indicates the battery cell is round.

ICR lithium Ion (Li Ion) requires a protection circuit for safety, whilst Lithium Iron Phosphate (LifePo4) and Lithium Manganese (LiMn or IMR) use safe chemistry. These batteries utilize safer chemistry so they do not require protective circuitry like ICR (lithium cobalt round) Li Ion batteries do. The safer chemistry will prevent venting with flames in the event of a catastrophic failure, while Li Ion batteries contain a volatile (flamable) chemistry.

Furthermore, the LiMn or IMR battery is capable of handling greater load demands than their cousins the Li Ion and LifePOs (in a much smaller package), and hence is commonly referred to as a "high drain" battery. Providing the battery has the appropriate C rating for the application, these are the recommended batteries intended for use with low and sub-ohm resistance atomizers.

The newer "hybrid" batteries combine chemistries of safe chemistry and ICR. They are also "high drain".
