Li-Ion Mod Batteries

We have 3.7 volt lithium ion cells in either ICR or IMR chemistry. The ICR cells have protection circuits and the IMR cells are "safer" chemistry so no protection circuit is needed. The table at the bottom of the page shows the cells we currently stock along with their specifications. There are also very simple explanations of the different types of lithium ion cells..

Measurements for Lithium Ion Cells

Lithium Ion Battery Chemistry

ICR (LiCoO2)

Chemical composition is lithium cobalt oxide
4.2 volt max charge, 3.7V nominal voltage
Not a safe chemistry, so should only be purchased with a protection circuit that guards against overcharging and over-discharging
Higher energy density, but lower charge and discharge rate

IMR (LiMn204)

Chemical composition is lithium manganese oxide
4.2V max charge, 3.7V nominal charge
Safer chemistry, so is not available with a protection circuit. But that means you must guard against overcharge and overdischarge themselves.
Slightly lower energy density than ICR, but can sustain much higher discharge and charge rates. Use these cells when an application calls for "high-drain" cells.

IFR (LiFePO4)

Chemical composition is lithium iron phosphate
3.6V max charge, 3.2V nominal voltage
Safer chemistry, so is not available with a protection circuit. But that means the consumer must guard against overcharge and overdischarge themselves.
Lower energy density than ICR, but can sustain higher discharge and charge rates.

Safety Alert

Be sure that the batteries that you are using match the e-cigarette manufacturer's recommendations.

For additional information on the proper usage and maintenance procedures for these batteries, please visit the Battery University. Be advised that "stacking" multiple batteries to achieve higher voltages is neither recommended nor warranted and can be incredibly dangerous.
