Something does not add up here… Nickel Metal Hydride self discharges, unlike Lithium Ion, and thus is a poor choice for a long term storage flashlight… I think there is some truth in advertising missing here…
But they use “specially-designed nickel metal hydride batteries”. I wonder if they are similar to Eneloop NiMH, which are better than regular NiMH.
