Because of temperature extremes in the car Lithium is the only type of battery I'll use in my accessories. Other types end up leaking. I also like the long storage for seldom used applications. I want them ready when I need them. Energizer Advanced Lithium AA Battery 4 Pack
These Energizer Advanced Lithium AA batteries are a wonder for my portable compact disc player and Wii remote. I'll put it to you this way. I have listened to 20 cds all the way through plus cds that I skipped around on and they still have juice (with anti-skip on). I put a fresh pair in my Wii remote and played Super Mario Galaxy 2 for the first time. I put in many many hours on the game even with the remote speaker on a lower volume (the way I like it). I beat the main quest while collecting over 90 stars and they were literally 2 hours away from making it it all the way through. I am happy to know that there are batteries like this nowadays that I can just put in to these devices and just forget about swapping for a long while.
Other pros: Lighter than alkalines (another plus for the Wii remote and certain other portable devices)
Better and Safer for the environment.
Cons: Some would say price, but thinking about it. I think it's justified. You don't have to swap out as much, carry as many around, they last about 3 or 4 times longer than alkalines (depending on device). And they are better for the environment.
I am going to stock up on these sometime for sure.
I have had pretty good luck with the Energizer lithium batteries. I have used them in a Digital Wall Clock and it lasted about 2 years. I also have used it in an AA battery camera and it seems to do about 2-3x longer life than regular Energizer or Duracell batteries. What is amazing is the lower prices for the product as I think they were 2x as much.
I used two of these batteries in a weather station, probably a low draw application. Manual estimates battery life at 1.5-2 years with alkalines. These lasted two months. Don't know if I got bad batteries or I used them in the wrong application. I'm thinking bad batteries as lithium cells are supposed to maintain their voltage over long periods and when they do finally die, their voltage drop off curve is precipitous.
I bought eight of these batteries for a specific audio application which requires that the battery be attached via solder to eliminate noise. I discovered the hard way that six of the eight batteries have a plastic case, including the top plate where the terminals are located. Attempting to solder the terminals caused some sort of internal failure/short on the plastic-cased batteries. I looked at the packaging the batteries came in, and there is no easy way to tell which are metal-plate and which are plastic-plate without taking the battery out of the blister pack. I now have six expensive, useless batteries that can't be returned.
Most people who buy this battery will probably use it with a clip-on connector so they won't have an issue, but the battery is sold for "professional audio" applications among other things. If your application is similar to mine, or if the battery will be subjected to a harsh environment, I recommend not buying this one. No matter what, it seems to me that Energizer took a "cheap" approach by making the terminal plate out of plastic. - Battery - Energizer - Lithium'
