18490 IMR 1100mAh 3.7V4.1wh Summary

IMR 18490 1100mAh 3.7V(4.1wh)

Safer Chemistry LiMN Battery

For High Powered rechargeable LIMN batteries, this is what you want.
These batteries provide the high power that is needed to power your personal vaporisers.
If you use Low Resistance / high amperage coils on mechanical mods, IMR is the only & safest way to go!
IMR Batteries use a safer chemistry construction this means that there is no risk of venting with a flame and or explosion. We highly recommend using these batteries.

About Li-Ion batteries
The specific energy of Li‑ion is twice that of NiCd, and the high nominal cell voltage of 3.60V as compared to 1.20V for nickel systems contributes to this gain.
Improvements in the active materials of the electrode have the potential of further increases in energy density.
The load characteristics are good, and the flat discharge curve offers effective utilization of the stored energy in a desirable voltage spectrum of 3.70 to 2.80V/cell.

Cost reduction, increase in specific energy and the absence of toxic material paved the road to make Li-ion the universally accepted battery for portable application, first in the consumer industry and now increasingly also in heavy industry, including electric power trains and for vehicles.

Li-ion is a low-maintenance battery, an advantage, many other chemistries can not claim.
The battery has no memory and does not need exercising (deliberate full discharge) to keep in shape.
Self-discharge is less than half that of nickel-based systems.
This makes Li‑ion well suited for fuel gauge applications.
The nominal cell voltage of 3.60V can directly power cell phones and digital cameras, offering simplifications and cost reductions over multi-cell designs.
The drawbacks are the need for protection circuits to prevent abuse.
