For Secondary (i.e., rechargeable CR123A batts)
For Primary (i.e., non-rechargeable CR123A batts)
Streamlight brand = 12 for $18.95
Surefire brand = 12 for $21.00
Surefire brand = 12 for $20.00
Titanium brand (recommended by the "guy" at Flashlight Reviews - he has test data comparing the "Ti" brand to some of the "big guys") Singles, or MATCHED PAIRS, and TRIPLETS = $1.00 each
NOTE that this $1 per batt is even if buying only ONE batt!
Test Data for Titanium brand vs. Surefire and BatteryStation-brand
be sure to look at the different graphs. Performance changes depending upon current draw. The Ti brand appears that it might have an "overactive", so to speak, PTC (positive temperature coefficient) protection that may account for its high current performance.
Note that for ~50 cents less per cell than most others, Titanium brand is a VALUE with, generally, just a bit less performance than the more expensive "big boys".
Battery Station (a bunch of brands)
Expensive KODAK and Sanyo brands
hope this helps. i'm still looking for another link i came across 2-3wks ago (96 cents each). i'll post back if i can find it.
Sorry 'bout the URLs. Hyperlinks no longer work for me after 2+ yrs of successful hyperlinking and posting to others to teach them how to mark up a HTML Anchor mark-up. The hyperlink doesn't display properly, nor work, and upon editing my Post containing the HTML, the HTML is mangled badly and is no longer what i typed, viz. the HREF portion is stripped out of it and is completely gone! Don't know why. Only started happening somewhat recently for me.
