Though there are other lithium ion chemistries (listed below), but usually when people talk about lithium ion batteries they are talking about lithium cobalt, '''LiCoO<sub>2</sub>''', after the chemistry of the battery anode (these batteries are also sometimes called LiCo, LCR, or ICR). They are available in a wide variety of sizes including CR123A, AA, and AAA. However, 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. | Though there are other lithium ion chemistries (listed below), but usually when people talk about lithium ion batteries they are talking about lithium cobalt, '''LiCoO<sub>2</sub>''', after the chemistry of the battery anode (these batteries are also sometimes called LiCo, LCR, or ICR).

Some brands of 10440, 14500, and 16340 cells are longer than their AAA, AA, and CR123 counterparts, so make sure you are getting cells that are not too long and that your light can deal with the size variance by reading the forums and reviews of the batteries and/or lights. Just because a cell is sold as an 18650 does not mean it is exactly 65 mm long: some are 68 mm long. | Some brands of 10440, 14500, and 16340 cells are longer than their AAA, AA, and CR123 counterparts, so make sure you are getting cells that are not too long and that your light can deal with the size variance by reading the forums and reviews of the batteries and/or lights.
