We design our Demonfire IMR 18350 rechargeable around two key principles: safety and performance.  Our IMR batteries utilize LiMn2O4 in the battery cathodes (negative end of the battery) which drastically lower the possibility of overcharging. Because of this safe chemistry, you can feel secure charging our IMR batteries in compatible chargers.  In terms of performance, our IMR 18350 batteries are high drain and give your devices the boost they need to reach peak potential.  Additionally, the flat top design of the anode (positive end of the battery) allows you to fit these batteries into devices with tighter battery slots.

Convenient 18350 Battery Cases

Our IMR 18350 batteries comes shrink wrapped for safety and packaged inside a handy storage case.  Each case can hold up to two batteries side by side and designed to protect your batteries from damage.
