You had to jump the battery because it was pretty dead.

Looks like your charging system is working its darnedest to get it charged again. Sounds okay to me.

Don't jump to conclusions until things get back to "normal" (a fully charged battery). If you want to make the alternator work less, charge the battery with a plug-in charger. Judge things only when the battery is all the way back up. In the mean time, don't freak out.
