Battery Fuji

How long do Ni-MH batteries last if they are unused after being charged?

I love the simplicity of digital cameras, but I get dissappointed at how fast my rechargeable batteries get drained. I use FujiFilm 2300 Rechargeable Ni-MH batteries for my Fuji Digi cam. The problem I'm having is that when I go to an event such as a sporting event, the batteries get very low after about 20-30 pictures are taken. So what I am wondering is, if I buy an extra set of batteries and fully charge them, and bring them with me to the event as a backup, will they still hold that charge so that I can stick those in the camera, once the other pair drains?

2300mAh NiMH rechargeable batteries should give you a reasonable amount of power (much more than 20-30 photos).

NiMH rechargeable batteries are designed to self discharge at the rate of approx. 1/2-1% per day when not used...so you should ALWAYS make sure that your charge them at least one day before...or on the day of intended use.
And also, when rechargeable batteries are brand new, it will take several discharge & charging cycles before they reach their full capacity.

Using Lithium non-rechargeable batteries such as Energizer e2, are a good alternative because they retain their charge when not used. However, I wouldn't recommend them as your only power source because they are throwaways and are quite expensive...but perfect as an emergency backup.

So, as long as you charge your batteries before an important event...then I don't see any problems whatsoever.
But remember, that a digital camera does require a lot of power to run...and you can also help to extend the life of your batteries by...turning off the LCD screen and using the viewfinder instead, limiting the use of the flash & zoom and also the reviewing of your photos.
good luck...
