I've been experiencing issues with my Moon Pulsar rear light (COB LED, 2xAAA batteries) dying after around 3-4hrs of use.
I thought this was a fault with the unit but have since tested another, NOS item with similar results. I'm running the light with 950mAh rechargeables; which when fitted are around 1.44v each for a total across both cells in series or around 2.88v. When the lights die the cells are at 2.3-2.4v.
I appreciate that Alkaline batteries are typically higher voltage than NiMH (the former listed at 1.5v nominal, the latter 1.2v), however am still a bit surprised by these results since it seems that Alkalines typically run down to circa 1.2v before they really drop off, while at 950mAh the lower capacity of the rechargeables (versus 1.5Ah typically for Alkalines..?) don't scale with the 3-4hrs runtime I'm getting versus the 46hrs published with Alkalines..
Can anyone with the capacity to understand this stuff offer any thoughts please?
I love these lights as they don't have integral batteries, so really want to make them more viable if possible..
