No, it’s ten days then it starts to discharge down to 65, per the link I posted above, then at day 12 it goes into hibernation.
They call it “wintering mode”
“Wintering mode
Ideally, when not in use for a prolonged period, batteries should be stored half-charged. When not in use for 10 days, Anafi’s smart battery discharges itself, if required, to 65% charge, over a 48h period.
In other words, after a maximum of 12 days without use, this smart battery enters hibernation with a charge level which never exceeds 65%. If you leave your battery for 12 days, you will find out its power button does not activate the charge level LED indicators.
The battery needs to be charged to exit the wintering mode and start operating as per usual, this behavior preserves the battery over time. Parrot recommends you always run a full charge of your smart battery before flying.”
