The battery chargers have been hit and miss. We sincerely apologize for the error. Were not 100% certain, but our current understanding of the problem is this. There is no auto shutoff once the battery drops below the Vdd=3.3V necessary to keep the chip running. Thus, various board voltage dividers and leakages will continue to drain the battery all the way down to...0. When this happens, the battery charger 'protects' the battery by charging VERY slowly. We have, however, seen different behavior on production maples that used a different charging chip (since the ones from the prototype were out of stock at the time). Thus, this may or may not be the root problem, were still working on it. The charging and done lights are flakey even on boards that effectively charge the battery. Once we verify exactly what the problem is on the production maples, or discover some user servicable fix (like a trace jump) well let everyone know.
Please let us know any results you have observed while experimenting!
