The computer makes use of this to retrieve information about the power adapter and to change the color of the LEDs on the power adapter's connector. The Apple MagSafe power adapter's 1-Wire communication chip is located inside the MagSafe connector itself; the cable does not carry the data line to the power adapter enclosure.
A battery charger, recharger, or simply charger, [1] [2] is a device that stores energy in an electric battery by running current through it. The charging protocol—how much voltage and current, for how long and what to do when charging is complete—depends on the size and type of the battery being charged.
Float voltage is the voltage at which a battery is maintained after being fully charged to maintain that capacity by compensating for self-discharge of the battery. [1] The voltage could be held constant for the entire duration of the cell's operation (such as in an automotive battery) or could be held for a particular phase of charging by the charger. [2]
The MagSafe Duo Charger is a foldable charging mat with a MagSafe charger on one side and an Apple Watch charger on the other. The Apple Watch charger disc can be laid flat for face-up charging or can be vertical for nightstand use. The MagSafe Duo charger can be folded when not in use.

A bad battery will have short I-phase and Uo-phase, but there is a risk of gassing, further damaging the battery. If a battery is connected to a significant load during charging, the end of the Uo-phase may never be reached and the battery will gas and be damaged, depending on the charge current relative to the battery capacity.
