Copied from your link:
While charging, a lower temperature will increase battery voltage. Full-charge voltage on a 12-volt battery is 0.9 volts higher at 32°F than at 70°F.
While discharging, a higher temperature will increase battery voltage.
Emphasis is mine. As Ronbo says also, those are while charging and discharging.
But thanks to all for clarifying.
