The Good
BG Micro’s latest newsletter still lists the Panasonic CR123 Industrial batteries for 75 cents each in quantity 10 or more. No free shipping but their shipping is reasonable if you buy enough to lower the per battery cost.

Claimed 6000 mAh UltraFire 26650 Lithium Ion battery for $10.49 each. I emailed them warning that the capacity was likely to be a total lie and we pretty much know about UltraFire quality and counterfeits that are even worse than the genuine items.
