CR123A lithium batteries, specifically. Anyone on my FL know a good place to buy them online that DOESN'T work out as expensive by the time you pay shipping as just going to a regular brick-and-mortar store? I just went to buy some replacement batteries for my Inova X0 LED flashlight (which takes two CR123As), and even if I bought four sets, by the time I paid the cheapest shipping offered (USPS priority mail), they're $4.50 a set shipped. At that price, I might as well buy them at Lowes and not have to wait for them to get here.
Oh, the salt? In a CR-123 lithium cell, it's most likely manganese dioxide.
