Where do they advise that? I’ve only seen warnings for alkaline batteries. There is a warning specific to alkalines on the website under the FAQ section.Shearwater advises to remove the battery from the Perdix, Predator, Petrel regardless of whether it's an alkaline, saft, lion, etc. for long-term storage.
There is also a Yellow warning box under alkaline batteries in the Perdix manual that advises not storing with alkaline batteries for longer than 2 months. I haven’t seen any similar warning for the other battery types.
