A salt, and battery

[unixronin]

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.

cost of batteries went WAY up lately.

which is why i love rechargeables a lot.

also got away from using cr123s mostly, but i know they have rechargeables for those too. probably worth it at the prices now.

it was actually cost beneficial to goto a flashlight that used AAs and was as bright or brighter than my then favorite EDC cr123 flashlight. i still have a few of those around, and they're worth as emergency lights, but not EDC.

I've seen CR123 lithium rechargables, but their charge density is rather poor compared to LiMnO₂ primary cells, and I understand that to maximize their life, you're never supposed to discharge them beyond 50%. Hard without a battery meter.
