Battery charger with LCD screens makes perfect sense
Rechargable batteries are great. You save money by not needing
to buy batteries every time they die, and you save the
environment by not throwing out acid-filled batteries every few
weeks. And this La Cross battery charger makes charging up
batteries a much more pleasant task, eliminating all of the
guesswork.  It does this using a LCD display to let you know
exactly how charged your batteries are. That way, you always
pull out the batteries with complete charges and leave the rest
to finish up. I also stops charging when they're full, so your
batteries won't get overcharged and have their lifespans
shortened. It's a great way to take care of rechargeable
batteries any way you look at it.  Via ThinkGeek
