When energizer brought the lithium chemistry to a 1.5v (in reality 1.7v) AA battery they gave the consumer a choice. I purchased these for a specific application, allow me to explain.
Earlier I had purchased the honeywell weather station (wireless) which relies on AA batteries – I think I used 28 doing the install. Some locations were a royal pain to get to and I did not want to try and change 4 batteries with 8 tiny screws on my roof very often.
Enter the L91BP. Batteries have a price. There is the cost of acquisition here on amazon, disposal, and the time spent replacing them. Let’s say you estimate your time at $40/hr which is reasonable for any engineer.
Assuming a good grade alkaline is $1/cell and these are $2/cell to change 4 batteries I am spending an extra $4. If they last 7 times longer, I’ve avoided 6 trips up on the roof to change them. If it takes me 1 hour to remove and re-install the batteries, then clearly at $40/hr I have come out ahead buying the more expensive cells, since I saved 6 changes, or $240 worth of my time.
I also put a second temp meter in my deep freeze and set an alarm on it on the receiver. Because alkaline cells dont perform in sub-0 temps, I used the L91-BPs again for that application.
Now the products that are easy to change the battery in did not get the lithium cells, however they may if removing the 8 tiny screws without loss becomes a pain.
Cons:
Because of their 1.7V output, some flashlights may be overvoltaged with 4 of these in series and caution not to use lithium AA cells.
We read about using lithium batteries in a digital camera. We bought these for a cruise we just took. We took over 500 pictures and some video with our camera. We are still using the first two batteries! Worth the extra cost for the amount of life you get and we don’t have to pack and take the recharger!
Even so, they last a long long time and the extra price is offset by the fact that you would be paying more to buy a comparable quantity of the other shorter-lived batteries.
However, when they die, they DIE (I have found that they don’t temporarily refresh themselves like the shorter-lived batteries do, when I turn off my camera and then turn it back on after a few minutes) — so keep an extra pair (or however many you use in that specific device) on hand for the day the inevitable happens.
And I believe that Lithium is more earth friendly — and if I am not mistaken, these can be recycled????
I have used these before. This 8-pak is priced better than a 4-pak at W-Mart. These batteries are great for digital cameras, they go much longer than regular alkalines.
I used these batteries in a digital camera and I was disappointed with the battery life. I haven’t used this camera before, so this review might be premature.
