Does anybody have any studies = with hard data to back up this conventional wisdom? I believe that Mac battery controllers severely limit the charge rate as = the battery approaches full charge. Hybrid vehicles typically limit their traction batteries within 20% - = 80%, but they are mostly NiMH. I don't know of any hard data for Li-ion. -- Bob Bishop rb@gid.co.uk
