I don't have a La Crosse BC-700 so I can't answer that but a friend of mine has his degree in electrical engineering and he's a pro photographer as well. He just bought a Titanium Smart Fast 16 Bay Ni-MH charger after I told him about it. I like the fact that it holds 16 batteries at one time. Comes with a car charger too. Go for it!
It's a scrappy charger. I returned mine and bought two lacrosse 1000s. The batteries should be warm, at most, to the touch. Hot is not good. Look for evidence of off gassing at the top of your batteries.
