Manker T01 killed my Windyfire!
Well, either I take this as a “Lesson learned” or it’s a mildly defective light. Either way, looks like I need to pick up some more 14500s.

So, over the last week to week-and-a-half, I left a Windyfire 14500 in one of my Manker T01s. It was in the car this whole time, off. I pulled it out yesterday to use, and I got nothing. I thought it was just another case of a loosened tailcap, so I went to tighten it. Already tight. Hmm. That’s odd. I happened to have an EA11 handy, so I used it to check the 14500 from the T01. Dead. I measured it on the dmm, and it read 1.8v. Ugh.

I’ll have to see if there is anyway to bring it back, but researching is going to have to wait until tomorrow.

I do not know what killed your Windyfire but some of my XTAR chargers have a so-called 0V Activation function. Not all of my NiMH batteries are of the LSD type and I kinda forget them every now and then. These batteries are revived from literally 0 Volt. After that I give them a refresh cycle in my OPUS and they are as good as new.
BTW The light I carry in my coat-pocket when I walk my dog at night is more or less my only light with a tight tailcap. All my other lights are kept with a loosened tailcap. Certainly my shelf and back-up light(s).

You are a flashaholic if you are forced to come out of the closet, to make room for more flashlights.

I almost always store them with loosened tailcaps. That’s why I was surprised. But I’m more surprised to find that the cell was drained THAT far. The only power being drawn would have been from the e-switch. I’m tempted to put a freshly charged cell in there and measure it after every 24 hours.

Also cars are strange when it comes to temperature.
They cool faster and get colder at night and heat up faster and get hotter during the day.
I had a thermometer with hi/low memory in it for months.
The low was significant lower then an outside hanging thermometer.
And in early spring when it was not nice and warm it showed 65°C (~150°F) so I can only imagine hiw hot it gets in summer sun (ha will pop the thermometer back in to see) now that when opening the doors feels like opening an oven.
No wonder those GPS devices never have a good battery life for long.
