I was worried, but subsequent day things looked "normal" again. It be day time and i be using no accesories. What does it mean??

Answers:    One of two things: Something shorted and be drawing power, or the alternator's regulator is going out and you dumped a ton of current into the battery.

My hunch is the extra workload on the engine increased your engine temp, and hence increased the temp of alternator's internal regulator. The extra warmness caused the ouput voltage to shoot up and you vitally started roasting the battery (had you pulled over while this be happening I bet you would hold heard the bitter inside the battery boiling).
