Hello My mbp is always being charged and I usually use it as a desktop rather than a mobile notebook. Even though it's always being charged, it started to stay at only 98% and didn't go up to 100%. Now it is staying at 97%. I'm a little fearful of that. Would not charging the battery connector straight into an electrical outlet on my wall be a problem? I use a 5-way connector thing that I plug my charger into and then that plugs into my electrical outlet. I don't know if that would be a problem, but that's more information to help you help me. Thanks if any suggestions. Happy Holidays.
