Energizer Ultimate Lithium L91 AA Batteries 20 pack for $9.99 at Costco! 50 cents per Battery!
$9.99
$21.98
Not sure if this is regional or YMMV, but my local Costco has 20 packs of Energizer AA Lithium batteries for $9.99! I have NEVER seen these cells for .50 each!
This was at the Ft. Myers, FL Store.

This is an instant savings deal for $5.00 off through Sunday May 10. I'm not sure when the price on these (regular price) went down to $14.99 (if it in fact has). I seem to remember these being normally priced at $18.99-$19.99? Maybe someone can confirm?
By way of comparison, an 18-pack of these is currently on special at Sam's Club for $18.98 after a $3.00 off promotion.

Time to stock up on these long shelf life, non-leaking batteries. You may never see a price like this again! I only wish they had the AAAs too! I

No Costco link because this deal is not available at Costco.com, only in the warehouse.
Maybe only in my warehouse by the look of things...
That's true, but standard (NiMH/eneloop) rechargeable batteries are just as good, and far more cost effective, for high-drain applications. Alkalines will lose 50-75% of their rated capacity when run at high currents (2A), whereas NiMH and the lithium AAs will both hold within ~10% of the rated low-current capacity. A good NiMH will have a 2200-2400mAh rating, while the lithium will have ~3000mAh. Certainly better, but Energizer sets a limit of 3A on them, while NiMH can pull as much as 5A (due to lower internal resistance).
The fact that they are great for trickle devices (and do not leak) means that you can use them in applications where you may only change them once every 5-6 years for micro-amp draw (backup clocks, volatile storage backup, lcd readouts) without worry. Likewise, for emergency power you can store them in the emergency flashlight/radio/etc. without worry of leak and expectation of good performance.
Using them for 50c-$1 a piece for a continuous high-drain vs a NiMH which may cost $1-2 means that the payback time is very, very short for the rechargeables (which also don't leak but don't have as long a storage life w/o charging).

I believe it is a nationwide coupon!
I use them for a smart lock that's outdoors because it handles the cold temp better and don't corrode when used for a long time.
