Yes, that’s true, especially if you get good Fujitsu factory NiMH like Eneloops, Duraloops, and others. However, alkaline still has one advantage over NiMH, and that is voltage. Even in 2018, some devices still aren’t made to be able to use NiMH voltage range and will turn off or just not work right because “the battery is dead”. :person_facepalming:
