Rechargeable: Difference between revisions

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 (therefore they do not come with protection circuits), they can still be made to explode if provoked sufficiently, unlike the LiFePO₄ cells which cannot. As a budget alternative to AW or Sony cells, [http://www.bestinone.net/index.php?route=product/search&keyword=imr&category_id=0 Best In One] has generic LiMn cells in a number of sizes. These cells are also sold in the US by Shaotech at [http://www.shaotech.com/ his store] and on CPF Marketplace.
