I own a mh20, great flashlight btw. I noticed that the running time was very short and after I measured the parasitic drain, I found out that it was from 10 to 40mA.
Have anyone else faced that?
edit. Today i received my mh20 after 45 days. I paid shipping cost once, for sending to nitecore and they paid for the returning.
My flashlight has a lot of dirt and some marks there weren’t there before.
On my MH20 it is 0.03 mA .
Initial reading will be high in 8+mA range, but it should reduce and stabilize in 20μmA range after 3-4 sec.
I have no way of measuring the drain. But I never have to physically lock it by loosing the tailcap. Never saw depleted cell in MH20 after long time sitting say three months. Selfbuilt’s review also says very low drain current.
“On the MH20, the final standby drain after the battery read-out was even lower, at 27uA. This would translate into over 13 years before a 3100mAh battery would be drained.”
Maybe your sample is defective? There used to be issues like this with their older model EC25.
Drain starts at 20 mamps while switch led is pulsing and stabilize at 0.03amps.
My 18650 2600mah is drained after some days, I am sure my sample is defective, I measured another one and showed 0 drain in standby.
I contacted bg cs and they told me they offer a 3 months guarantee for flashlights¿
Contact Nitecore .
They offer 5 years warranty .

The MH20 is very easy to lock out at the tail cap with about 6mm of a turn.
