Got a TN36-UT in the mail today. Using Keeppower 3500mAh (P1835J) batteries charged to ~4.2v. These were the recommended batteries from the supplier I bought it from.
Worked initially. Although sometimes the button seemed to not work unless I pressed it harder. It also seemed like it would skip modes every so often when I was cycling through low/med/high. After 10 minutes of use, the light just stopped working. It won’t turn on no matter how I press the button. The blue LED light on the button doesn’t work either (can’t remember if it ever did).
I checked various things:
- Batteries still had plenty of charge
- Batteries inserted correctly
- Spinning around the reversible battery holder
- Manually pressing the battery holder onto the plate of the light
- Tightening the thread that connects the two pieces
- Loosening the thread that connects the two pieces
Checking to see if I accidentally triggered an electronic lockout (there is none)
Seems like it’s just faulty and I should get it replaced. Anyone with any suggestions?
I can’t imagine why. Seems to be perfectly in tact. Batteries are also a fairly tight fit. It also doesn’t explain why it would suddenly stop working mid use.
What do you mean by pull the spring forward? I did have a look by removing the screws earlier. The piece of metal sitting on top of the spring seems to be making contact, as it springs back up after I depress it.
The spring is already making contact. You can’t screw the back plate on without it depressing the spring. I push the center piece of metal and it bounces back, because the spring is there.
Update: I have returned the light to the store. Hopefully they will send out a new one that works.
