Menard's, a regional building supply chain has frequent RayOVac USA, and "Northtech", Chinese battery sales. I usually buy boxes of 48 AA & AAA RayOVac cells for about 14 cents each with rebate and packs of eight 9v batteries for about $10. I've yet to have any leak and they last well in storage. The RayO and other US made 9v batteries usually supply ~2.5 - 3 "flash" amps into a short. The $1 each, Chinese Northtech 9v sunk a whopping six amps. I've had good luck with the Northtech AA & AAA, so I'm interested to see how these will last.

Any thoughts about the very low internal resistance or difference with the Northtechs?

The store was also selling four packs of 600mAh, 18500, rechargeable lithium cells for $7. These were in the solar decorative outdoor lights, which all seemed to use AA NiMH cells, instead. I'm not familiar with that type of low capacity lithium cell.
