As I understand things, this is indeed the case in the US, but not in other countries.
Thanks a lot for the review! Frontpage’d and Sticky’d.
One niche that these batteries can fill is emergency use in high current applications. If you can’t recharge your NiMH batteries, and alkaline batteries just don’t have the oomph, these are a good choice. This is especially true for digital cameras, which are notoriously bad with alkaline batteries (and for which L91 lithiums are actually MUCH more cost effective).
Of course, resistance to leakage is also a good use for L91 batteries as an alkaline replacement. Certain devices may not need the higher current capabilities of lithiums. But if the replacement cost of the device is very high, Energizer Lithiums can be a good choice. A good example here would be expensive multimeters and other electronic instruments. Current demand is low. But the last thing you want is leaking alkaline batteries in a Fluke.
I’ve noticed that the packaging of new Energizer Lithium’s says they have a shelf life of 20-years.
Did they change anything, or is the shelf life realistically better than the 15-years they’ve advertised in the past???
Has anyone tested the Tenergy primaries side by side with the Energizer?
I bought a few AAA’s to do a test vs alkaline, but its a non-scientific test.
However it proved to me that energizer AAA alkaline die quicker than Tenergy Lithium AAA in my GMRS radio.
One set had to be replaced every 1.5 - 2 hours. The other lasted over 4 hours, and still has juice.
Anyone wanna get some solid numbers for a vs like an old member did here for li-ions?
DuraCell Alkalines now advertise a life of 10 years. Not sure if the extra money is worth another decade...I just rotate my stock.
