Energizer Lithium Batteries Review
Excellent product........even better than advertised.
One problem...I have total faith in Amazon best pricing, and since I
bought from you, found several local establishments, Ex. Walgreen's that are selling it for much less with no shipping and handling charges. I will be very careful to cost compare in the future.

Depends on the application.
I love these batteries!
Something to consider tho, is that a Warehouse Club 48-pack of regular 2800ma alkalines are about the same price. So for low-current applications where maximum life, cold weather performance, weight, etc. isn't critical, there are much more cost-effective choices.
AND speaking of critical, I had a little digital safe at the office (for postage stamps, the checkbook, spare car keys, and such) that ran on AA's. I used it for years on regular alkalines and replaced them every 3 months or so. When the alkalines got low, it would still weakly open 5 or 10 times to give me plenty of time to change them. When I switched to a set of these lithiums (to reduce how often I had to do the replacement procedure) they lasted just over twice as long, BUT when they died, they were totally gone-ola. I think they're way better at putting out full voltage to the end - which is ordinarily what you want out of a battery, unless you lock the manual-opening keys in the safe itself!
