Am new here, got a Lumintop SD mini in July last year and it worked fine until last week. Once I charged it to full capacity, it’s power drains off in 24 hours time. Tried it again yesterday and the same happened.
There was a SD mini that I gave to a friend, worked fine for months and then came back with a completely dead battery, 0 V (an LG). I gave him a new battery with the advise to lockout the light after use by twisting the tail off a bit. I never investigated what precisely happened but it could be the same thing.
Do you, or someone you know, have a DMM that can measure down to micro amps? Off current (parasitic drain) is pretty easy to measure if you have a meter and know how to use it. I suspect the results would be enlightening.
