Discharge rate can also have a great affect on the batteries available capacity. The ratings listed on the label of a battery are calculated at a much lower rate than the batteries maximum discharge rate, quite often around 0.2C. This means a 2,600 mAh battery was tested at a current draw of 0.52 amperes. As you raise the rate of discharge, the available battery capacity becomes smaller and smaller.
IMR batteries have a safer basic chemistry than ICR batteries as they can sustain higher internal temperatures before becoming unstable. The manganese cathode has a much lower internal resistance as well, which is the driving force behind the higher drain ratings because resistance has a direct correlation to heat generation. It should be noted that an IMR battery which does not specifically have the “high drain” designation can not, and should not, handle high current draw. The design of the electrodes themselves has a Battery Types large effect on the maximum drain rating of a battery. IMR batteries can have maxiIMR mum discharge ratings as high as 78C but most on the market today have a safe IMR, or Manganese cathode batteries zone up until about 10 amps. This is likeare modders preferred battery type. ly due to the balance of higher IMR batteries originally used a simple capacity and high drain of todays batmanganese cathode which provided teries. It is critical never to assume the for much higher discharge rates than maximum discharge rating though. If in its ICR counterpart. This was not with- doubt, Google can be used to quickly and out a loss though. With the manganese easily find your batteries datasheet which will clearly state the safety zones.
high drain cathode, IMR batteries had a much smaller duty cycle and overall battery capacity was nearly half of the ICR. Over time, manufacturers started mixing manganese with nickel to improve the duty cycle and capacity of the battery with only a slight reduction to the maximum discharge rate
ICR
ICR, or Cobalt electrode batteries were the original form of lithium ion batteries. ICR batteries are known for their higher capacities and are perfectly suitable for the average vapors device. Typically capable of a maximum current draw of 23C,with some newer batteries capable of10 amps, these batteries can handle mostatomizers we buy over the counter today.
