The existing docs here are a bit vague. This reformats and rewords it, and is based upon the wording originally used by the dell-laptop driver battery documentation and also sysfs-class-power-wilco. The wording for "Long Life" and "Bypass" remain the same, because I'm unfamiliar with hardware that use them.
