Sorry for the off-topic question, but does anyone know how lithium-ion batteries(such as laptop batteries) like to be treated? Do they prefer to be kept charged, like lead-acid batteries, or do they prefer to be cycled deeply, like nickel cadmium or nickel metal hydride? I realize there's a sophisticated charge controller chip handling things, but if a change of my habits can effect the lifespan, I'm interested(I'm also superstitious when it comes to rechargeable batteries). Thanks, Bob
