I am wondering how much time it can run in mode high.
Hava any person tested it?

Great write up, I (my dad) have a MT2A. Very similar in most aspects, must say that it is a good simple UI but I think that hidden blinky and L-M-H (like phantom23 said) would make it a tad better. That is relly my only gripe with the light.

I know this is an old, old thread, (and a great review by the way!), but I was wondering if anyone who still owns one of these has had trouble with parasitic drain?

I pulled mine out a few weeks ago and installed fresh Energizer Ultimate Lithium AA’s, (expiration date of 2023), and used it for a job under the kitchen sink for about 5 minutes. I turned it off and set it on a table. I went to use it again yesterday and noticed the beam was very weak. I checked the freshly installed cells with a multi meter and they were over halfway depleted.

Anyone notice this with yours? I know you can lock out the switch by loosening the tail cap but I hate lights with parasitic drains.

I’m not sure about the MT22A but I have two of the MT2As (similar light) that I keep in the cars with eneloops. I charge the batteries every 6 months and they’re never dead when checked.

I remember a time, when I searched for lights to fit my needs. Now I search for needs to fit my lights.

Mine’s the MT21a as reviewed here. Maybe mine’s defective but other than the weird battery depletion it works fine.

My mistake, MT21a.

I suppose with a jumper wire and couple of extra hands you could put a DVOM in series with the tail cap and measure parasitic draw.

I’ve had an MT21a for about a year now and keep it around as a mostly unused emergency light. I put energizer nimh batteries in it and charge them once a month to keep them topped off. I don’t lock out the tailcap and they always have a good charge left in them at the end of the month, so if there is parasitic drain its minimal.

Thanks Itinifni but I don’t have the technical knowledge to do that.

Thanks jch10400 for the feedback.

Like the stated in his review, even on turbo this is not a barn burner or anything even remotely close. It was a nice light back in 2014 but oh, has light technology advanced since then.

It’s still a nice light but parasitic drain, at least in my example, makes it a not so nice light.

I swapped the LEDs in both of my MT2As and XP-G2 5A1 in one of them and XM-L2 U5 7A3 in the other. Within the limits of a 2AA light I think they’re great!

I had mine since it was available.

I’ve had put it in the car for emergencies (and stuff). Been there for a couple of months on average. Two times I had to use it and the Eneloop XX batteries dies in less than 15 minutes on high. Back then I just thought that the batteries are losing charge after time, but now when you mentioned it, maybe there IS parasitic drain.

I retired mine and I’m using some SolarForces with 18650 in the car now. Never had a problem like this since.

Thanks for that verification Ventsi. It looks like some of these DO have parasitic drain.

These were pretty nice just two short years ago but can’t hold a candle to what’s available today.

It’s truly amazing how flashlight technology has marched on especially in the last few years. Flashlight are like computers were a decade ago changing for the better almost monthly.
