You are describing battery sizes, not chemistries. 18650 is a standard cell size which Tesla uses in their older vehicles, and is common in older laptops and powertools. The types of chemistry used in it may vary (just like you can get AA cells in alkaline, NiCd, NiMH, and other chemistries)
- makomk 9y agoNo I'm not. 18650 is the size, NCR1850B is a very specific model of off-the-shelf cell in that size manufactured by Panasonic with a specific chemistry and specification. As far as I can tell (it's not something the manufacturers release much information about publicly) the "NCR" part identifies the chemistry as Lithium Nickel Cobalt Aluminum Oxide.
