These cells allow higher drain ([[Terminology#C|5C]], up to 8C) than LiCo cells without some of the dangers. AW sells these as IMR (supposedly based on "LMR" for lithium manganese rechargeable, but the lower case "L" was mistaken for an "I" and never corrected), and Sony as Konion. They can be charged in most li-ion chargers, but some li-ion chargers will overcharge LiMn cells. LiMn cells should be charged at 1C to 2C. Due to lower overall capacity, these batteries fill a niche with flashlights demanding very high current where runtime isn't that important. While they are safer than lithium-ion cells | These cells allow higher drain ([[Terminology#C|5C]], up to 8C) than LiCo cells without some of the dangers.

While they are safer than lithium-ion cells, if they are shorted out in an enclosed space like a flashlight, they will discharge with a huge amount of energy potentially causing a fire even if the battery itself does not explode. | ||
