By distraction I turned off my Hypermotard 1100 S with the key in position P, as a result the battery was discharged. The question is this: if you discharge the battery without having detached it from the bike, when it is recharged or when it is reassembled after detaching it, do you have to redo the CO and TPS controls?

Dear Maurizio, the adjustments to which you refer are not to be repeated with each discharge of the battery: however, to preserve its life it is advisable to submit it to a controlled charging cycle. The battery that reaches the full discharge must in fact be subjected to a preliminary low current charging cycle for at least 10-12 hours: the amperage in this delicate recovery phase should not exceed 0.5 A. After that, the battery can recharge normally with a current of 2.5-3 A for the necessary time (in your case about 12 hours beyond those of the preliminary phase).
It is obviously mandatory to use a state-of-the-art electronically designed charger and the classic “transformers” used for cars are banned. Full discharge is a very dangerous event and in some conditions can permanently affect the functionality of the battery.
