New Lithium Ultimate batteries test 1.79 to 1.83 volt, this is why in most cases they will last longer.
They are designed for cold weather use. Normal alkaline batteries test 1.55 to 1.60 volt. Using the
Lithium Ultimate in Canada, camera set for 30 second video and operating a 32 GB SD card, the cameras
quit functioning when the Lithium voltage drops to around 1.6 volt. Now install alkaline 1.55 or 1.60 volts
using this card the camera will continue to work until the voltage drops to approximately 1.3 volt. It took
considerable testing to find out why the camera failed at 1.60 volt with the Lithium but worked with the
alkaline at the same 1.60 volt. It was the size of the SD card which was the maximum recommended for
that camera.
Switching to an 8 GB SD card has I did not have any 16 GB, the 1.60 Lithium Ultimate would carry on working.
I tested several brands in the 32 GB size with the same results. These larger cards take a lot more energy
to run them, especially on video (my interest). If you have not done so, set your camera to video, say 30 second
and take some random videos around home. Place the SD card in your computer and open, where you will see
a list of videos it has recorded. On the right hand side of each unopened video, you will see the amount of kilobytes
that video has. For comparison, if you have an older model camera (these will be limited to may be 4 or 8 GB SD
card) and do a similar test. Your video will show pretty much the same quality but checking the kilobytes, there will
be a way less.
Cameras set for pictures, require a lot less power as they are not recording like when taking a video. It is just an
instant shot. There are a lot of options on these new cameras, but one should have the option of turning off what is
not required to save battery power when taking videos.
All the best.
