 '''Important:''' ''***These are not the same as [[Primaries#Lithium|disposable lithium batteries]] sold by Energizer (Energizer e2 or Ultimate Lithium), Saft (who make it more confusing by selling 3.6V lithium cells that are not rechargeable), and other companies since those can not be recharged and will explode if you try it ([http://www.candlepowerforums.com/vb/showthread.php?t=250219 example]).***''
-Lithium ion batteries are typical in mobile phones, where they offer higher density of charge storage. In other words, more amps can be stored in less size and weight. They can also be referred to by the chemistry of the anode (positive) which is lithium cobalt oxide (LiCoO<sub>2</sub>). They do not suffer from the "memory effect." However, they cost more, and are not as long established as the older AA, C, D, types typical in torches.
+Lithium polymer batteries are typical in mobile phones, where they offer higher density of charge storage. In other words, more amp hours can be stored in less size and weight. They can also be referred to by the chemistry of the anode (positive) which is lithium cobalt oxide (LiCoO<sub>2</sub>). They do not suffer from the "memory effect." However, they cost more, and are not as long established as the older AA, C, D, types typical in torches.
 Because of the higher voltage, Li-ion cells can only be swapped for NiMH or alkalines if the device manufacturer recommends it (Be careful! A fully charged li-ion battery has 3 times the voltage of a NiMH cell). Some flashlights that use two CR123A batteries can take a single 18650 battery (though this battery is wider than CR123A cells) which offers substantially more capacity than the two smaller cells together.
