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.
