These cells allow higher drain (5C) than li-ion cells without some of the dangers. AW sells these as IMR. 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. | These cells allow higher drain (5C) than li-ion cells without some of the dangers.

While they are safer than lithium-ion cells, they can still be made to explode if provoked sufficiently, unlike the LiFePO4 cells which cannot. | ||

A classic rechargeable battery. Never much used for mobile application due to poor size / weight characteristics. However, very reliable if kept topped up, cheap, and as such, often still used in cars, if not torches. | A classic rechargeable battery.
